Changelog

What's new

Every release, newest first. The launcher checks for these itself, so you only need this page for the details.

What's new#

This beta collects everything added since 0.5.0 (the previous beta was never published), mostly in the Arctic Client. The version ranges say where each feature works.

Arctic Client: new#

Lock Slots: Alt + click locks a slot (a padlock shows on it; clicks and the drop key are blocked there). Modern versions and 1.8.9 to 1.12.2.
Inventory Search: Ctrl + F in a chest or your inventory finds items by name. Modern versions and 1.8.9 to 1.12.2.
Shulker Peek: hold Shift over a shulker box for what is inside, Shift + Alt for every slot. The window takes the box's colour, and chests, barrels, hoppers and other containers that carry items work too. Minecraft 1.11 and newer.
Command Palette (Ctrl + K): search mods, servers and friends, and jump into Quick Join game modes.
Combat Feedback: a hit marker, hit and kill sounds and a low-health warning.
Saturation Bar now works like AppleSkin: a golden overlay on the hunger icons your saturation covers (a whole icon for 2 points, half for 1).
No Hurt Shake: the view stops tilting and shaking when you take damage. 1.14 to 1.21.11 and 1.8.9 to 1.12.2.
Dynamic FPS: a lower frame rate limit while the game is in another window, idle or in a menu. 1.14 to 1.21.11 and 1.8.9 to 1.12.2.
Particle Control, Held Item (where your hand and its item sit in first person) and Portal Screens (the inventory, chat and menus stay open in a Nether portal).
New HUD widgets: CPU, PC CPU, PC RAM, allocation rate, GPU, VRAM, frame time and 1% low; Block, Fall and Pearl; a floating TNT timer. Every widget can hide while Tab (the player list) is held.
Tab Ping shows the number where the game's ping bars are (1.16 to 1.21.11 and 1.8.9 to 1.12.2). An Arctic badge shows above heads of Arctic players (1.16 and newer).
OptiFine capes without OptiFine: players who have an OptiFine cape and no Arctic one show theirs (Mods, OptiFine Capes).
One Arctic button opens a hub: Configure HUD, Mods, Replays, Friends, Presets, Accounts and Menu Style, with a badge for unread chat and new features. The Mods menu has categories (Combat, Inventory, Movement, Tools, Players), HUD widget groups, NEW marks, presets and distinct icons.
Server list in game: hover a row and its icon becomes a play arrow, and clicking the icon joins at once. Disconnect screens stay the game's own when you chose the game's server list.
Debug Screen can hide groups of F3 lines (version, FPS, coordinates, light, entities, system, targeted block and more), has its own text size, and its colours work on 1.21.9 and newer.
Emoji button in the chat, and pop-ups on the connecting and loading screens.
Fonts: the smooth font is pixel-sharp by default (Menu Style, "Smooth edges" brings the soft edges back), with softer shadows under it. Fancy works with Patcher's font renderer on 1.8.9.
Shoulder pets blink.
Motion blur, redone: it smears along the picture's movement from the camera's turn (and a stretch when you move forward), with no ghost copies. Pick a mode (turning and moving, turning only, moving only) and a strength slider. Hand and item blur too.
1.7 Animations (1.8.9): the sword swings while you block, swing while eating, drinking and drawing a bow, the 1.7 bow stretch, smooth sneaking, and the 1.7 item position in first and third person.
Chat: click a line in the history to copy it; Chat Mute (players and words, also gone from history and search); timestamp options (12-hour, AM/PM, seconds, brackets, bold, italic); keep the chat when you leave a server; stacking options (time frame, ignore blank lines and dividers, also on 1.8.9 to 1.12.2); a Hide chat toggle; Auto Text answers a chat line by itself (when it says X, send Y).
Quickplay: join Bed Wars, SkyWars, Duels and other minigames with a click, and play the last one again.
Particle Control per kind (smoke, flames, explosions, crits, portal, water, potion, redstone, lava, block breaking).
Visual and view: Damage Tint (the screen flushes in a colour you pick when you are hit), Snaplook (hold a key to see yourself from the front), Hide Titles, Fog (push it away or remove it; Fabric 1.14 to 1.21.4 and 1.8.9 to 1.12.2), Glint Colorizer (held and menu items, 1.8.9 to 1.12.2), Mob Size (every creature but players bigger or smaller; 1.13 to 26.3 and 1.8.9 to 1.12.2), Chunk Borders (1.14 to 26.3 and 1.10.2 to 1.12.2), and a Sound Changer that quiets or silences single sounds by a piece of their name.
Widgets: Cooldowns (pearl, chorus, wind charge, shield; 1.14 to 26.3), Horse Stats (speed and jump of the horse you ride or aim at; 1.16 to 26.3 and 1.8.9 to 1.10.2), a Looking at widget (the block or creature under your crosshair), and the Items widget counts the items you choose.
Scrollable Tooltips (1.8.9 to 1.12.2): a tooltip taller than the screen moves with the mouse wheel.
Any colour on every swatch row (a picker with hex entry), and a Rescan button for controllers on 1.8.9 to 1.12.2.
Hitboxes and Chunk Borders switch on and off at once on 1.21.11 to 26.3 (they used to need a rejoin).

Launcher: new#

Change an instance's mod loader: another build of the same loader, or Fabric, Quilt, NeoForge or Forge on the same Minecraft version. Its mods are looked up first, and the ones without a version there are turned off, not deleted.
Duplicate instance: a copy with its own folder, the same mods, packs, settings and configs (worlds when you ask).
Send logs to staff: a button in the Logs tab sends the log you are looking at (user name, folders, e-mail and IP addresses and tokens taken out) and gives you a short code to paste in your ticket.
A global "Play with Arctic Client" switch in Settings, set in setup too.
Setup can add a desktop shortcut (on by default) and asks, once and optionally, how you heard about Arctic. Only your answer is sent.
Crash reports can carry a contact (a Discord name or e-mail) and read the game's latest.log and Java's crash file when the game dies quietly. Java's crash file is trimmed first: no command line, VM arguments or environment variables.
Import HUD layouts from Fast Client and Silent Client.
Settings in groups and a sidebar in sections. The instance page says when the client is off for everything. Play times over a day read as days. The mod download bar sits above the search field with a percentage.
Mac: the app is signed and notarized by Apple, so it opens without a warning. Homebrew works: brew install brksfrb/arctic/arctic-launcher.
OptiFine capes of your accounts in Cosmetics, Capes: one click wears one as an Arctic cape, so Arctic players see it with or without OptiFine.
Pick the modpack version: every modpack in the browser has a Versions button listing its versions with their Minecraft version and loader.
Names the system can't find: when Windows can't look up a website (error "No such host is known"), the launcher asks Cloudflare over HTTPS instead. It is not used behind a proxy; set ARCTIC_NO_DOH=1 to turn it off.
Link your Discord to your Arctic profile, which also restores an offline account on a new PC.

Fixed#

The 1.8.9 to 1.12.2 mouse pointer comes back on open screens (a grabbed mouse or an empty cursor, seen in fullscreen).
Glow-ink sign text no longer flickers with the smooth font (1.21.9 to 1.21.11).
The Mods menu's category chips wrap instead of running past the panel.
In the Logs tab the mouse wheel and dragging past the edge scroll while you select. Friends' screenshots and chat pictures are decoded with size limits, and chat pictures no longer show empty.
The page's scroll bar sits on the window's edge.
The game no longer fails to start with a damaged arctic-mod.jar: it is checked before every start and written again when it is broken.
Arctic's HUD widgets no longer disappear while hitboxes are on (1.21.11 to 26.3).
A controller stick that kept the player walking after it was let go is released.

Fixed#

The launcher reaches its servers on more PCs where Windows can't look up website names. When Windows can't find a site, the launcher now asks Cloudflare, Google and Quad9 over HTTPS at the same time (whichever isn't blocked answers first), and if all of them fail it uses the address the site had the last time it was found. The error message now says when those lookups were blocked too. Not used behind a proxy; set ARCTIC_NO_DOH=1 to turn it off.

What's new#

Fixed#

The launcher works on PCs where Windows can't look up website names. Some PCs showed "No such host is known" for Mojang, Fabric or GitHub, so creating an instance and the update check failed even though the browser worked. When Windows can't find a site, the launcher now asks Cloudflare over HTTPS instead (not used behind a proxy; set ARCTIC_NO_DOH=1 to turn it off).
The game no longer fails to start with a damaged arctic-mod.jar. The file is checked before every start and written again when it is broken.
Entity hitboxes from Arctic switch on and off at once on Minecraft 1.21.11 to 26.3 (they used to need a rejoin), and Arctic's HUD widgets no longer disappear while hitboxes are on.

New#

Pick the modpack version. Every modpack in the browser has a Versions button that lists its versions with their Minecraft version and loader; Install still takes the newest release.

A friend with an offline account can join your world through Play Together. The world checked every joiner's Microsoft sign-in, so a friend without one was turned away with "Invalid session, try restarting your game". When you play with an offline account yourself, your world no longer asks for it. This works on Minecraft 1.14 and newer; 1.8.9 to 1.13.2 will follow.

The game no longer crashes a minute after starting on PCs that were short of memory ("Failed to commit memory"). Windows can run out of memory it is able to hand out while other programs are open, and the launcher didn't look at how much was left. It now gives the game less when little is left, and keeps some free for your other programs.

Joining some servers no longer ends in "Network Protocol Error" (SyroMC's shulkers, for one). The Performance switch's Polarium mod (now 0.31.3) asked a mob for its size before the mob was fully made, which the game turned into a lost connection. It now answers as the game does.

An offline name is never lost. Every offline key is now also kept in two backup copies, restored from them if the main file ever lacks it, and a file that can't be read is set aside instead of overwritten. Before a key counts as lost, every key saved on this PC is tried (older ones, other profiles, backups). This fixes "this name is used by another Arctic player" after an update.

Fullbright now takes effect when you switch it. With a mod that caches the game's light map (BadOptimizations, which the Performance switch adds), the switch could seem to do nothing and the world stayed as bright, or as dark, as it was.
The Join button in the server list takes clicks again (the row's drag layer lay over it, so it showed the grab hand and ignored the click).

What's new#

Bedrock Edition (Windows)#

Play Minecraft for Windows from Arctic: start it, switch its version, and manage its worlds, packs and servers (a new Bedrock tab). Worlds import and export as .mcworld.
Any version, older or newer: switch between every release and Preview build, including the older ones before 1.21.120. Windows installs them with the Store licence of the account that owns the game. Older packages you download are kept, so going back needs no second download.
Our own Bedrock client is on its way. Third-party clients (Latite, Flarial) are switched off for now; the Bedrock tab says so.

Arctic Client#

Forge 1.8.9 now has the Arctic Client (installed by the launcher into Forge 1.8.9 instances): HUD, menus, notices and cosmetics, with the same settings as the other versions.
Forge 1.8.9 Performance switch: adds Patcher and Entity Culling from Modrinth (ones you already have are left alone). Patcher's own font renderer and its OneConfig menu key (Right Shift, also Arctic's) are moved aside after its first start.
Minecraft 1.13.2 is supported.
Hitboxes shows every entity's hitbox with one click (like F3+B), on all versions.
Saturation Bar draws your hidden saturation as a gold line on the hunger bar, on all versions.
Ping Tags show other players' ping in front of their name tag, My name tag shows your own ping, tier and name as others see them, and Find Me in Tab makes your own row pulse.
Fullbright can skip light calculations. The Performance switch also adds Particle Core and BadOptimizations.
Shoulder pets and new cosmetics, free for everyone.
Disconnect screens explain what happened: a timeout, a refused connection or an unknown address each get a plain sentence, and Escape goes back to the server list.

Launcher#

HTTP proxies (CONNECT) alongside SOCKS5, in the launcher, the CLI and in game.
Play time per server, world and instance, with a Stats tab, and per instance on the Play page.
Look for updates on an instance's Mods page, with Update all; optional extra mods per instance, starting with Wavey Capes.
Recent worlds are backed up before the game moves to a newer version.
Crash help: explanations name the mod to update when the loader suggests it, mods left over from another Minecraft version, a Fabric Loader that is too old, and a game that stops without writing anything. "Fix it" buttons switch off leftover mods or update Fabric Loader. Crash reports include the launcher log and the exit code.
Discover: only servers that let any name in are tagged "cracked" (a Microsoft account is the normal case, so "premium" is gone). A few servers got their proper names.
Skin gallery: a Minecraft collection with the nine default skins.
Friends: Add a friend is its own card; the privacy settings are a labelled Privacy & profile button.
Launcher logs: the last five are kept (launcher.1.log is the run before), and a log starts with the date and time.
Discord: the About page, the suggest dialog and the last onboarding step now invite you to join the Discord (help, updates, promotions and giveaways).
Tray: the first time you close the window it asks whether to keep Arctic in the tray, with a plain explanation (also asked in onboarding). A launcher waiting in the tray no longer restarts itself for an update unless you allow it.
Animations and the glass blur stay off when the graphics driver draws in software (ChromeOS, virtual machines); nothing animates while the window is hidden.

Fixed#

Moving an instance's mods to another Minecraft version no longer shows "These mods won't start together" for the Arctic Client, Polarium and the Performance mods: the launcher puts the right versions in when the game starts, so those leftovers are not a problem.
Friends' screenshots in chat show as pictures again (they were empty bubbles), and are decoded with size and memory limits.
On 1.8.9 to 1.12.2 the mouse pointer is given back to an open menu (it could be missing in fullscreen).
The instance page's Extras are a card of their own, and a mod's download progress is a full-width bar with a percentage above the search field.
Offline names can't be lost on the same PC: the key is stored readably, the recovery code is made and kept automatically, and settings, accounts and keys survive a power cut. Concurrent saves of one file no longer overwrite each other.
A refused Arctic sign-in is not retried every few seconds.
Bold text with the smooth font on 1.8.9 to 1.12.2 is thickened, not drawn twice a pixel apart (titles looked doubled).
On 1.8.9 to 1.12.2 the game follows its window after the launcher maximizes it (it could draw a small picture in a big black window).
Zoom's smooth camera no longer stays on after zooming when OptiFine's zoom had switched it on first.
Disconnect screens keep the server's colours, and the launcher no longer warns that Entity Culling is for another Minecraft version on Forge 1.8.9.
Leftover copies of an interrupted launcher update are removed at start.
The pointer is given back to an open screen (it was hidden after the loading screen in fullscreen, and after Alt+Tab).
Reconnect goes to the server being joined, not the last one that worked.
Servers behind Cloudflare no longer hang when joining through a proxy.
Motion blur on 26.1 and newer shows again and no longer leaves stale frames.
The cosmetics catalog is requested once when it gets old, not once per frame.
Forge 1.8.9 starts again (its Mixin service files were missing, and one hook targeted a class Forge loads first).
"My name tag" has its icon, and the "Send to…" button lines up with the buttons beside it.

Known issues#

Bedrock support has had little testing on real installs: tell us if installing or switching versions fails.
Minecraft 1.13.2 and Forge 1.8.9 are new; report anything odd.
Waypoints can step instead of gliding while you move.

What's new#

Bedrock Edition (Windows)#

Play Minecraft for Windows from Arctic: start it, switch its version, and manage its worlds, packs and servers (a new Bedrock tab). Worlds import and export as .mcworld.
Any version, older or newer: switch between every release and Preview build, including the older ones before 1.21.120. Windows installs them with the Store licence of the account that owns the game. Older packages you download are kept, so going back needs no second download.
Clients: pick Latite or Flarial under Bedrock and it is loaded into the game when you press Play. They are made by other people and downloaded from their own releases; some servers ban modified clients.

Arctic Client#

Forge 1.8.9 now has the Arctic Client (installed by the launcher into Forge 1.8.9 instances): HUD, menus, notices and cosmetics, with the same settings as the other versions.
Forge 1.8.9 Performance switch: adds Patcher and Entity Culling from Modrinth (ones you already have are left alone). Patcher's own font renderer and its OneConfig menu key (Right Shift, also Arctic's) are moved aside after its first start.
Minecraft 1.13.2 is supported.
Hitboxes shows every entity's hitbox with one click (like F3+B), on all versions.
Saturation Bar draws your hidden saturation as a gold line on the hunger bar, on all versions.
Ping Tags show other players' ping in front of their name tag, My name tag shows your own ping, tier and name as others see them, and Find Me in Tab makes your own row pulse.

What's new#

Chat#

Chat History (Arctic menu): every line since the game started, across servers, searched as you type, with saved keyword filters (diamond, trade, -spam) and a copy button.
A second chat on screen: the new Filtered chat HUD widget shows the newest lines that match one of your filters.
Longer scrollback on every version (1.8.9 to 26.3): the game's 100-line limit is now a setting, up to 100,000 lines.
Emoji and symbols: type :heart: or :star: and it sends the symbol, or pick one from the Emoji and Symbols page.

Packs#

Groups for resource packs and shaders, in the launcher and in the game (the same groups in both). Files never move.

Launcher#

Gentle launch (Settings → Launching): a few downloads at a time and the game starting at low priority, for computers that freeze under load.
Optional desktop shortcut, a background picture of your own, and an instance settings button on the Play tab.
Gameplay videos show on the instance's Replays page, with Play, Show in folder and Trash.
Offline accounts show the face of the skin they wear; the Microsoft sign-in page looks like Arctic.
Screenshots grow out of their cell when opened and shrink back when closed.
Importing a world can take it from your other profiles' instances too.
Forge and NeoForge instances say why the Arctic Client isn't available there.
Cosmetics Check (Arctic menu): shows whether the game is signed in to Arctic, the UUID it plays as, and what lookups found, for "why can't they see my cosmetics?".
Emotes card in the Arctic menu to rebind the emote wheel key.
A text box cursor everywhere in game: arrows, Home/End, selection with Shift or the mouse, Ctrl+C/X/V.

Fixed#

Offline accounts with "invalid name or key": an unreadable saved key is replaced instead of being sent empty. If the name was claimed with the lost key, use your recovery code. Sign-in attempts and failures are now written to the launcher log.
Auto reconnect goes back to the server you were joining (also when you were kicked while joining), supports delays from 0.1 s and a tries limit, and works on 1.21.11.
Leaving a server, or cancelling a join, lands on the server list; the game's own multiplayer and disconnect screens no longer flash before Arctic's.
1.8.9 zoom sensitivity now matches newer versions; the zoom sensitivity is a stepper.
Minecraft settings that an older game doesn't know (entity distance, for one) are no longer reset when you play that older version.
Mods built for Legacy Fabric (Legacy OptiFabric and others) are found in the Modrinth browser on 1.8.9 to 1.13.
Screenshots pop up right away; copying no longer holds the pop-up back.
A death waypoint and "Last death" no longer carry over between worlds with the same name.
A HUD widget dropped on the bar comes back where you can grab it.
Starting another Vanilla version while one runs says why, instead of an "in use by another process" error.
The replay on/off switch, and the videos folder opens in your file manager.
The logs page keeps scrolling while you drag-select text.
Copying a server address in the server editor works.

Known issues#

Waypoints can step instead of gliding while you move (under investigation).
Some players report HUD widgets missing until they open the emote wheel (under investigation).

Arctic Launcher v0.4.8

October 14, 2026 · 49 downloads

What's new#

Replays#

Two independent recording controls. F9 saves the last 30 seconds; F10 starts or stops a recording. Change either key and the instant-clip length in Arctic's replay settings. Saving an instant clip leaves an ongoing recording running.
Game audio in new recordings and videos. Replay playback and MP4 exports include recorded game sounds. Older recordings remain playable without an audio track.
Smaller clips and faster saves. Compression and removal of obsolete entity history reduce storage and processing, especially in crowded worlds. Saving a clip now acknowledges the key immediately and finishes in the background. Size still depends on activity and duration.
Explicit video rendering. MP4 rendering is off by default and can be started with Render queued videos. It uses the Minecraft window, so you cannot play during rendering. Queues from an earlier launch wait for you to resume them; Escape pauses rendering.

Instances and menus#

Installed mods have a search field. Large mod lists scan in the background and draw only visible rows so the instance page stays responsive.
Arctic keeps native menu controls, including controls added by other mods, while applying its styling and title branding.
Arctic's server browser opens by default and stays selected after closing settings; the native server screen remains available.

Fixed#

Dragging the scrollbar in Arctic's mods menu now scrolls the list.
Replay camera controls and paths refresh correctly after editing keyframes.
Rewinding keeps the replay editor, camera direction and pause state without replacing the view with a loading screen. Large seeks can still pause while the world is reconstructed.
Replay respawns clear the previous death pose.
Crowded-world replay buffering handles bursts more efficiently and keeps cleanup work off the packet writer.
Video exports wait for terrain and apply the camera before capturing their first frame; audio seeking works on older Minecraft versions too.
A queued video opening cannot interrupt a newly joined live game.

Known issue#

Some players report Arctic HUD widgets missing after joining until they open the emote wheel. This intermittent issue is still under investigation and is not claimed fixed in this release.

What's new#

Packs and shaders#

Browse shaders in game. Open Packs & Shaders in Arctic's menu to find shaders on Modrinth, install them, and turn them on or off with Iris. Downloads also work before shader support is enabled; the page explains how to enable it in the launcher.
Filter your search. Choose a category, resource-pack resolution or shader performance impact, and sort by downloads, relevance, newest or recently updated. Browse this Minecraft version or all versions; installation still checks compatibility with your game.

Linux#

Flatpak distribution with signed updates. Install Arctic from our Flatpak repository (opens in a new tab). Your Linux software manager handles updates. The repository is published from Arctic's existing GitHub project.

Fixed#

Fabric's internal mod resources no longer fill the in-game resource-pack list. Applying your choices keeps those internal resources available to the game.
Resource packs added to the launcher's folder appear automatically while its pack list is open.
Pack searches no longer silently fall back to a different Minecraft version when no compatible results are found.

Arctic Launcher v0.4.6

October 13, 2026 · 20 downloads

What's new#

Fixed#

Fabric file repair now reaches the mod loader. After a missing-library crash, the repair could finish after checking only vanilla files, leaving a damaged Fabric or Mixin library in place. It now checks both stages and keeps the repair pending if preparation fails.
Play checks Fabric's key libraries automatically. Damaged copies with a published checksum are replaced even when an older launcher did not request a repair.
Missing-library crashes keep their actual explanation. A large modpack on a computer with little memory no longer causes this error to be relabeled as insufficient memory or disables its automatic repair. Memory warnings remain available before launch.

Arctic Launcher v0.4.5

What's new#

Fixed#

Big modpacks on computers with little memory: a computer with 4 GB could give the game only 1.9 GB, too little for a large pack that opened fine in other launchers. It can now give up to all of its memory when Windows' page file can back it (slower, but it starts), and the launcher warns when a big pack gets too little.
A crash from too little memory is explained as that ("Not enough memory for this many mods"), not as a damaged game file.
Server list ping times are right: they showed about 100 ms too much.

What's new#

Fixed#

Server list pings finish: servers no longer sit at "PingingΓÇª" after you come back from a server or open Discover, and Multiplayer no longer crashes while the pings come in.
Smooth text without dark edges on 1.17 to 1.21.11 (it was already fixed on 26.1 and newer).
Boss bar has its icon in the mods menu, and the Scoreboard and Boss bar settings show a preview even while the real ones are on screen.
Continuity and Sodium: a mod that only needs a newer version of another now offers Update first, instead of saying they can't run together.
Play together: the invite code wraps inside its card in a narrow window.
Theme and client style tiles stay inside their rounded borders.
Discover servers: Sort has its own row, so Surprise me no longer covers it.
A game that fails before any mod loads (a part of the mod loader that can't be read) starts next time with its files checked and without Arctic's start-up speed-ups, and its crash report says how Java was started.

New#

Big modpacks get more memory by themselves when their instance has no memory setting of its own (80+ mods 5 GB, 150+ 6 GB, 250+ 8 GB, never more than your PC can spare).
Trash on the Instances page: removed instances are listed there, and you can bring one back in one click or delete it for good.
Modpack and mod search keep loading as you scroll down (they stopped at the first 20).
Share looks up mods you put in by hand on Modrinth, so mods copied from another folder are shared too.
Menu Style is a button next to Edit HUD in the Arctic Client's mods menu.

Arctic Launcher v0.4.3

October 13, 2026 · 23 downloads

What's new#

Fixed#

The launcher no longer keeps resizing itself on screens with display scaling (125%, for example): Auto interface size measured the screen again right after changing size, and flipped between two sizes. This update installs by itself.
Cosmetics previews: items sit in the middle of their cards, faces seen at a slant (a brim's underside as you tilt) no longer vanish early, and cubes inside each other stop flickering.
The character preview keeps its size while it turns.

Cosmetics#

Skin gallery is easy to find: Skins, Skin gallery and Capes sit together under Looks, and the gallery opens first when you have no skins yet.
Your own capes stay: every cape you add keeps its card on the Capes page, so you can switch between them in one click (right-click one to remove it).
Adding a skin or a cape is a card at the front of its list.
Zoom further in the character preview (0.4├ù to 4├ù); zooming in moves toward your face.
Shadow Brim: a new black wide-brim hat (Head).

Arctic Launcher v0.4.2

October 13, 2026 · 17 downloads

What's new#

Fixed#

Minecraft settings no longer reset after playing 1.8.9 and then a newer version in the same instance (Vanilla plays both in one folder): the newer game failed to read the settings 1.8.9 had saved, started on its defaults, and those spread to every instance.
Skins and capes on 1.8.9 to 1.12.2: with an Arctic cape, your skin came out invisible or scrambled and the cape showed your skin. Both are back where they belong (emotes that bend arms and legs used the wrong one too).
Text on 1.8.9 to 1.12.2: obfuscated text (&k) no longer shakes from side to side, and big text like titles is smooth instead of grey-edged.
Item physics: dropped items lie on top of snow instead of disappearing into it, and items a server holds in the air (shop displays, holograms) no longer spin and tumble forever.
Disconnect screen: a long or multi-line reason no longer runs under the server address or into the buttons.
Replays: a long recording on a busy server keeps compacting instead of stopping at the size limit.

Arctic Client#

Sort Discover servers by most or fewest players, or by name, in the launcher and in game. Random stays the default.
Direct Connection remembers the last address you joined, as in vanilla.
Sliders on 1.8.9 to 1.12.2 (Music & Sounds and the others) get the Arctic look too.

Performance#

Polarium on Minecraft 26.3: with a thousand players in view, about 145 FPS instead of 33 (26.2 and 26.1.2 get the same Polarium version).
The launcher uses less memory: fonts for other scripts load only when they're shown, the capes page keeps still images until you hover one, and memory goes back to Windows when the launcher is hidden, minimized or behind the game.

Launcher#

Interface size (Settings → Appearance, and the first start): Auto makes the launcher a little smaller on small or highly scaled screens, like a 1080p laptop at 150%, so everything fits; or pick 80% to 150% yourself.
Cosmetics without an account: look around the Cosmetics tab and the skin gallery before signing in; the gallery has collections now.
Glass theme: dialogs, menus, dropdowns and pickers are nearly solid, so their text reads over the aurora.

What's new#

Fixed#

Big Fabric modpacks start again with the Arctic Client (COBBLEVERSE and others on Fabric Loader 0.18 or older): the game no longer crashes at start with "Mixin transformation … failed" / "ArrayList cannot be cast to AnnotationNode".
Modpack downloads no longer hang: one stalled connection used to hold a big download (a 239 MB modpack, say) for over an hour. Big files now arrive in small pieces, and a piece that stops is fetched again on a fresh connection.

Launcher#

Choose where Arctic keeps its files: Settings → Storage moves everything (game files, Java, worlds, accounts, settings) to another folder or drive, and the first start asks too. Each instance can also keep its worlds, mods and packs in a folder of its own, or use an existing .minecraft folder as it is.
Quick tips in the sidebar: one of Arctic's features at a time, a new one every few minutes; click to open it. Settings → Show quick tips turns them off.

October 12, 2026 · 23 downloads

What's new#

Arctic Client#

Play with a controller on every version (1.8.9 to 26.3): Xbox, PlayStation and other gamepads walk, look, fight, use the hotbar and inventory, and move a pointer through menus. Arctic → Controller sets look speed, pointer speed and inverted looking.
Tier Tags: players' PvP tiers by their names, in name tags and the tab list ("HT3 Sword | Steve"), from PvPTiers or SubTiers.
A new server list on every version: drag servers to reorder them, see icons, MOTDs, the ping, players (hover for who's on) and the version each server runs, find LAN worlds, and discover public servers. Lost connection? Reconnect in one click, or turn on Auto Reconnect.
A new minimap: smooth instead of jumping, square or round, north-up or turning with you, with players and waypoints on it.
The scoreboard and the boss bar move, resize and hide in the HUD editor like any widget.
Cosmetic fit: move glasses and other face items up, down, closer or farther to sit on your skin's eyes, or wear a shoulder pet on the other shoulder. Every Arctic player sees it.
The emote wheel shows how many pages of emotes there are (29 emotes, 3 pages).

Launcher#

Glass theme: the aurora night through frosted cards and sidebar.
Mod clash check: before a modded instance starts, Arctic looks for what would stop the game (the same mod twice, a mod that breaks another, a missing or too old requirement, a mod for another Minecraft version) and fixes it in one click.
Required updates install and restart by themselves; this "What's new" shows after each update (you can turn it off in Settings).
Portable mode also starts from a file named portable.txt.txt (what Windows makes of "portable.txt" when it hides file extensions).
Server rows on the Play tab can be dragged anywhere, glide aside and scroll the page, like the game's own list.

Fixed#

Crashes explained right: a damaged game file now says so (and the next start checks and fetches fresh copies), as do a memory setting the computer can't give, a full thread stack, and VulkanMod or graphics driver failures (including picking the wrong one of two graphics cards).
Fewer crashes: Vulkan no longer runs out of LWJGL stack space at start; 1.21.9 to 26.3 no longer crash when someone joins or leaves while player heads load; 1.8.9 no longer crashes accepting a server's resource pack; the memory setting is kept within what the computer has.
Essential and other big modpacks work again on Fabric: Arctic's faster start no longer loads game files before other mods have set up, which broke Essential ("Could not initialize class gg.essential.api.EssentialAPI") and crashed some packs at start ("Mixin transformation … failed", e.g. Cobbleverse).
Held items follow your hand in emotes that bend the arm.
Elytras painted from Arctic capes are no longer see-through from the side or from above.
The Cosmetics tab's capes open without a pause.
Button text sits in the middle of its button.
Replays no longer fill the drive on busy servers.
Videos aren't attempted while VulkanMod draws the game (it doesn't use OpenGL); a message says so instead of a crash.

Motion blur no longer makes the game dark on 1.15.2 to 1.21.11. The blur mixed every frame with black, so turning it on dimmed everything.
Motion blur works with VulkanMod (1.21.6 to 1.21.11), and Arctic Client with VulkanMod no longer crashes when you join a world.
Elytras no longer disappear with an Arctic cape. Every Arctic cape now comes with its own matching elytra wings.
The Arctic title screen buttons now follow the game's language.

Arctic Launcher v0.3.3

October 10, 2026 · 49 downloads

What's new#

A required update: on slower connections, downloading a new Minecraft version could fail with "timeout: receive body".

Fixed#

Downloads no longer fail on ordinary home connections. The launcher downloads many files at once and gave up on any that weren't fast enough on their own; now a file only fails if its connection really stops, and each one gets more tries.
New versions are ready sooner: about 260 MB is downloaded before the game starts instead of about 640 MB. Music, music discs and other languages arrive in the background while you play.
The Arctic snowflake now shows on players who just joined (it could stay hidden for 10 minutes).
Settings sharing no longer brings back notices you already dismissed (the "Third-Party Online Play" warning kept returning).
1.8.9 to 1.12.2: the scoreboard is no longer faded with the smooth font, and "Invalid session" is fixed by renewing your session and joining again, without restarting the game.
Minecraft 1.16.5 and older can reach today's websites again (skins, OptiFine capes: "Cannot contact authentication server").

Smoother games#

Fewer FPS drops. Games now use a better garbage collector: on 1.21+ (with 8+ CPU threads and 3 GB+ for the game) far fewer frame-dropping pauses, at no FPS cost; on 1.8.9 to 1.20 about a third of the hitches. Collectors you set in your own JVM flags are kept.
1.8.9 to 1.12.2 run faster.

Emotes#

17 new emotes: Hello Wave, Respect Bow, Triple Clap, No Way, Over There, Quick Salute, Hmm, Side Shuffle, Wake-up Stretch, Heartfelt Thanks, Showboat Spin, Take a Seat, Achoo!, Zen Hover, Twerk, Facepalm Act and Victory Hop. They move the whole body: bending elbows and knees, sitting down, spinning, hopping.
Emotes now work on every version, 1.8.9 to 26.3, and the emote wheel has pages (scroll for more).

Instances#

Move an instance to another Minecraft version with its mods. In an instance's settings, pick a version and "Check mods": you see which mods have a version there (they're updated) and which don't yet (they're turned off, not deleted).
Drop a mod file on any tab of an instance to add it.
Start the game maximized (Settings, next to fullscreen), on Windows, macOS and Linux.
"Use the gaming graphics card" now works on Linux laptops too.

Arctic Client on more versions#

Zoom, Freelook, Fullbright, chat options, crosshair, weather and time, scoreboard options, hit color, minimap, in-game account switching, duels, motion blur, item physics, block outline color and Arctic-style buttons now work on 1.15.2 to 1.19.4 too.
Replays on 1.15.2; the Arctic backdrop in menus before 1.20.6; the smooth font reads better on 1.20.5 to 1.21.11.

Arctic Launcher v0.3.2

October 9, 2026 · 54 downloads

What's new#

A required update: 1.8.9 to 1.12.2 couldn't start with Arctic Client in 0.3.0 and 0.3.1.

Arctic Client (in game)#

The smooth font works on every version now, 1.8.9 to 26.3. Turn on Fancy (Arctic → Style, or the launcher's Settings) to use it. Text stays sharp at any GUI scale. Characters the font doesn't cover keep Minecraft's own font.

Fixed#

1.8.9 to 1.12.2 start again with Arctic Client (a cosmetics change in 0.3.0 stopped them at launch).
1.15.2 starts again with Arctic Client.
1.16.5 with Performance on no longer stops at "EntityCulling requires fabric".
Text lines up with the buttons beside it across the launcher, and all buttons are the same height.
"Restart now" after an update can no longer leave a frozen launcher window behind.

Arctic Launcher v0.3.1

October 8, 2026 · 22 downloads

What's new#

Updates install themselves. The launcher now downloads and installs new versions on its own and uses them the next time you open it. If it's waiting in the tray with no game running, it switches over right away and stays in the tray. A launcher left open checks again every few hours. After an update you'll see a short "Updated to …" note with a link to what's new. You can turn this off in Settings → Updates → "Install updates automatically".

Fixed

The in-game Mods menu now opens with an empty search. A search left over from earlier could hide mods such as Motion Blur and Item Physics.

What's new#

Arctic Client (in game)#

Motion blur and item physics (dropped items lie flat and tumble as they fall), on 26.1–26.3 and 1.8.9–1.12.2. Both are in Mods → Visual.
1.8.9–1.12.2 catch up: the minimap, duels and switching accounts in game.
3D cosmetics on every version (1.8.9 to 26.3), with a soft shine on sculpted pieces. New: 20 sculpted cosmetics, 2 HD animated capes, 50 skins and an arms slot.
HUD: new widgets take your HUD style; Arrows and Held show just the item; the Compass pointer color can be changed; World time and Entities have proper icons.
Servers that ask whether you use Arctic or Polarium (like BotPvP) now get an answer.
Offline accounts can be added from the in-game Account page.
Looks (skins, capes, cosmetics, emotes) are now chosen in the launcher only; the emote wheel stays in game.

Launcher#

Windows search finds the launcher: it adds itself to the Start menu.
Feedback: suggest a feature or report a bug from the launcher, with cleaned-up logs if you like.
Instances can keep their own settings instead of sharing them with your other instances.
Modpacks: a Modpacks banner on the Instances page, drag-and-drop .mrpack install, and .zip packs with a Modrinth index install too.
Discover → Partners: servers hosted with Flash Hosting.
Import lets you pick exactly what to bring in from another launcher.
Styles: Classic is a black theme now, and the new Vanilla style keeps Minecraft's own menus.

Faster starts#

The game reaches the title screen several seconds sooner: only the Fabric API parts in use are loaded, classes are loaded ahead on other cores, the game's own classes aren't re-verified, files aren't re-checked on every start, and the loading screen fades out faster.

Fixed#

Copying screenshots to the clipboard works again.
26.3 no longer crashes at startup, and joining servers no longer fails with a "Network Protocol Error".
Each launcher page keeps its own scroll position.
Polarium copied for the wrong Minecraft generation no longer stops the game from starting.

September 26, 2026
Test build for Windows (pre-release). Things may still change.

New since v0.1.0:
- Friends: add by friend code or Microsoft name, see who's online and where, join or invite, chat and send screenshots, in the launcher and in game (Right Shift → Friends)
- Discover servers: a public server list shown in a new random order every time, plus pings for your own servers with who's online
- Screenshots tab, and a pop-up with the picture when you take one in game
- Resource pack and shader browser (Modrinth) per instance
- Default game settings for every new instance (FOV, render distance, volumes, keys…), shareable as a code
- Import from other launchers and clients: official launcher, TLauncher, Prism, Modrinth App, CurseForge, ATLauncher, GDLauncher, LabyMod, Lunar, Feather and Badlion (including HUD layouts)
- Share codes for HUD layouts, crosshairs, instances and whole profiles
- Arctic Client works on Minecraft 1.20.1 to 26.3, with sharper text and many fixes
Some online features (friends, chat, server list) come online with the next server update.
