Athas v0.4.5

What's new

Language servers, fully heard: Type hints drift in beside your variables, parameter help appears the moment you open a paren, and if the server crashes, Athas quietly picks it back up.

Hit the mic: Talk to the agent instead of typing.

Introducing Worktrees: A new panel in the Git sidebar, right beside changes and stashes.

Remote, without the detour: Connect to a remote host and it opens as a project tab — browse, edit, and switch the same way you do locally.

Extended CLI commands: athas web, athas terminal, athas remote. Three small doors into the editor.

What we fixed

Git feels calmer

fetch, push, and pull no longer freeze the editor while they run. The git actions menu always stays on screen, the gutter updates smoothly on Linux, and the pull request viewer works on older gh CLIs.

The editor stays out of your way

Inline edit has a proper toolbar and a rebindable Cmd+I. Shortcut chips everywhere in the app update the moment you change a keybinding. Pane fullscreen stops killing the terminal inside it, and the tab bar is there even when you've closed everything.

Terminal, less fussy

Profiles and shell selection, proper paste, ANSI codes out of tab titles, and Cmd+W focusing the right thing.

Small good things

Svelte highlighting. A rebuilt SQLite viewer. A warmer first-run onboarding and an in-app What's New tab after updates. Telemetry off by default. Signed Windows builds with SHA256 checksums alongside every release.

Thanks

@Finesssee, @Lyapsus, and @ChristmasSun— thank you for this cycle.

Athas v0.4.4

Syntax highlighting hotfix

Syntax highlighting was silently broken in all production builds since v0.4.0. A security hardening change removed the CSP permission needed for WebAssembly, which prevented tree-sitter parsers from loading. This release restores it.

Athas v0.4.3

Problems pane, CLI opening, and model selector redesign

Highlights

• New Problems pane that surfaces diagnostics with quick actions — click a warning or error to jump to the source, or apply a code action right from the pane
• Open files and folders straight from the terminal with athas foo.txt or athas ., and deep links via athas://open
• The AI model selector has been completely redesigned into a single unified dropdown with inline API key and Ollama URL editors, provider icons, and full-width search across all providers
• Adjustable UI font size in Settings > Appearance — scales text and icons across the entire interface
• You can now create new files with Ctrl+N even when no folder is open

Improvements

• Default AI provider is now Anthropic Claude Sonnet 4.5
• Language extension installs use bundled parser assets instead of fetching from CDN
• "Go to File" has been renamed to "Quick Open" everywhere
• XML-family files (xml, xsl, xslt, svg, plist) now get syntax highlighting
• Sticky line numbers in file preview so they stay visible while scrolling

Bug Fixes

• Language servers now properly activate after installation on Linux
• Switching between files no longer causes stale highlighting, wrong cursor positions, or scroll jumps
• Syntax highlighting works correctly after updating from older versions (stale cache issue)
• File drops work reliably on Windows, and file tree lag on large repos is reduced
• Terminal fonts render correctly on Windows with platform-aware fallbacks
• GitHub PR menu correctly detects expired tokens instead of showing a cryptic error
• Menus close properly when clicking outside on Windows
• macOS text replacements now work in the terminal
• Diff viewer hunk accordions actually toggle when clicked

Athas v0.4.2

What's Changed

Syntax Highlighting — Rebuilt from the Ground Up

Every tree-sitter parser (all 35 languages) has been rebuilt from source using the latest tree-sitter-cli, resolving a long-standing WASM ABI version mismatch that silently broke syntax highlighting across most languages. Highlighting for YAML, JSX/TSX, and SQL now works correctly, and all grammars use the modern dylink.0 format expected by the runtime.

New: SQL Syntax Highlighting

SQL files are now fully supported with syntax highlighting powered by a dedicated tree-sitter grammar — previously, SQL had no highlighting at all.

Editor Polish

• The inline edit model selector now uses a cleaner sparkle icon
• GitHub PRs panel layout has been tightened for better readability

Under the Hood

• Removed the pre-built tree-sitter-wasms package entirely — all 35 parsers are now compiled from individual grammar sources during setup
• Switched YAML, Markdown, and Vue grammars to the @tree-sitter-grammars maintained forks (C-compatible scanners for reliable WASM builds)
• Updated YAML highlights query to match the new grammar structure
