Changelog

Latest

v3.0.63 October 20, 2026

Added

• Compact chat: AI replies stay in the main chat, while its thoughts, commands, searches and edits fold into one line you can click to expand. Settings → Appearance → Chat activity restores the detailed view.
• MCP servers for everyone: no subscription needed.
• Accessibility themes: High Contrast and Distinct Colors, each in dark and light.
• “Allow always” per project: remembered per project, even after a restart, with a status bar button to turn it off.
• Editor settings that apply: tab size, word wrap, minimap and a right-side sidebar now take effect right away.

Improved

• A task that reaches its step limit ends with a summary of what it did and what is left.
• Long MCP browser tasks keep running on their own and keep only the newest page snapshot in memory.

Fixed

• Spell-check in the chat input works again on Linux.
• A reply’s final answer is no longer joined onto its first sentence.
• Cortex no longer crashes while closing on Linux.
• Saving a long chat no longer drops its older replies.
• Signing in no longer freezes the window.
• A stopped task no longer repeats its progress lines at the end.

Removed

• The UI Scale setting; use your system’s display scaling instead.

v3.0.61 October 17, 2026

Added

• Bundled fonts: Inter and JetBrains Mono ship inside the app, so no font install is needed. The editor lists only the fonts that are present, and the terminal gains font family and size settings.
• Twelve colour themes plus Cortex: one setting styles the editor, the menus, the status bar, the terminal palette and the chat surface, and it is applied at startup.
• Prompt queue: up to two prompts can wait while the agent works. Edit or remove a queued prompt at any time, and the draft is kept.
• Boot screen: an animated Cortex mark with a progress sweep while the app starts.

Fixed

• A refused video no longer disappears without a message.
• The personalization block is appended at the end of the prompt.
• DeepSeek stall detection uses a monotonic clock, so a system clock change cannot freeze the stream.

v3.0.60 October 13, 2026

Fixed

• The stray Cortex AI IDE window no longer appears at startup.

v3.0.59 October 13, 2026

Added

• Voice input in 60 languages — Malayalam, Tamil, Telugu, Hindi, Arabic, Chinese and more. Choose yours under Account → Voice input; they appear next to the mic.
• Auto-detect for mixed speech, such as Malayalam with English words.
• Send automatically switch: turn it off to check spoken text before it’s sent.
• History lists every chat by date, with search.

Fixed

• Resume continues a long task instead of doing nothing.
• Long tasks keep their context, and chat history survives a crash.
• A long, silent command no longer logs you out of the Linux desktop.
• Light mode: tooltips, Copy Path and the mic icon follow the theme.

v3.0.52 September 28, 2026

Added

• Use any OpenAI-compatible provider — NVIDIA NIM, Groq, or your own Ollama or vLLM server. Add one under AI → Custom Providers…, paste your key, and its models appear in the dropdown straight away.
• Custom Providers dialog for adding, testing and removing a provider in one place.

Fixed

• Provider toggles save cleanly: switching one provider on or off leaves every other provider exactly as it was.
• The enable switch beside a custom provider saves, and stays set across restarts.
• The model dropdown matches the provider switches — a provider you turn off no longer lists its models.
• Streaming runs to the end with providers that send an empty usage field, such as NVIDIA NIM.

v3.0.47 September 22, 2026

Fixed

• Long conversations keep their whole history. Reopening a chat restores every message and writes it back intact, however far you scroll.
• Everything after a code block renders. Tables, headings and paragraphs that follow a fenced block are all kept.
• Large PDFs open smoothly. Rendering yields between pages, and opening a second PDF takes over from the first.
• Messages recovered after an unexpected shutdown come back fully formatted.

v3.0.45 September 19, 2026

New

• Project Health Map. A Health icon in the sidebar opens your codebase as a wiring diagram: every file a node, every import a wire. Click a file and its wiring lights up — green for what it imports, yellow for what imports it, red for anything touching a broken file.
• Dead-code census. The same window lists the symbols and files nothing references any more, with the scan log that found them.

Improved

• Long agent tasks run to completion: the watchdog looks for real work (tool calls, output, edits) instead of the clock.
• The dead-code census reads every text file, not just Python, and knows which methods frameworks call by name.
• Every font stack in the Linux UI now comes from one Linux-native token list.

Fixed

• The Skill tool reads the same skill library as the Skills browser and the "/" menu.
• The dead-code list scrolls properly on big projects, and off-screen rows skip layout so thousands of findings stay smooth.
• The wiring legend stays docked in the canvas corner while a node is selected.

Performance

• Health Map rebuilds its lists once per typing pause and handles row clicks with a single listener, so search and filtering stay instant on large graphs.

v3.0.35 September 13, 2026

New

• One terminal, shared with the AI. Cortex and the agent work in the same live shell, so a cd it makes is still there for your next command and you can watch what it runs.
• AI access to a server you are signed in to. Open an SSH session in a terminal tab and Cortex offers the agent that session — granted per session, revocable at any time.
• Run button on shell code blocks. Shell snippets in chat get a ▶ Run that types the command into a terminal, so you can read it first.

Improved

• Screenshots and pasted images are resized before sending, and only the newest image goes when several are attached.
• Thought cards render reasoning as clean text: escape sequences decoded, long code blocks folded, markdown formatted.
• Question cards show each option's description, not just its label.
• Terminal tabs size themselves to their real width when you switch back, and the file explorer refreshes only the folders that changed.

Fixed

• Closing a terminal tab is instant.
• Provider errors are reported in the chat, and an empty reply is retried once.
• The .git folder is listed in the file explorer, like every other dotfile.

v3.0.25 September 7, 2026

New

• Live model list. Cortex now fetches the available models from the server, so newly added models appear in the model dropdown without waiting for an app update.

Improved

• OpenRouter Auto reports which model it routed each request to, so you can see what actually ran your turn.
• Crash reporting is now enabled properly at startup; if Cortex crashes, a report is written to the crash directory.

Fixed

• Chat restore no longer hangs on messages containing tables; the infinite loop in table splitting is gone.
• Collapsed tables in chat keep their header row when re-expanded.
• Disabling an inherited MCP server now actually disables it; its shadow was written at the wrong scope.
• MCP servers whose command is npx or uvx now launch on Windows; the command is resolved before launch.
• Switching tabs with a large file open no longer stalls the editor; the file is passed by URI.

Performance

• Chat restore rebuilds fewer widgets per message and normalizes tables inline, so long histories open noticeably faster.
• Tool-result cache cleanup now actually runs, keeping memory flat during long sessions.

v3.0.23 September 5, 2026

New

• OpenRouter Auto. Pick openrouter/auto in the model dropdown and OpenRouter routes each request to the model that fits it, with a 1M context window and up to 32K of output.

Improved

• MCP servers honour the standard per-server timeout field, and each call now gets one clear time budget instead of competing deadlines.
• Long MCP calls are supervised on server health rather than a fixed stopwatch, so slow-but-alive servers are no longer cut off mid-call.

Fixed

• OpenRouter Auto failing agent turns with a "no models match" error.

v3.0.22 September 1, 2026

New

• MCP servers work out of the box. Cortex reads your existing Cursor and Claude MCP configuration, so servers you have already set up are available with no extra work.
• Plan mode. Let the agent lay out its approach before it starts changing files.
• Skills from every agent tool. Cortex discovers skills from any agent tool's skills directory, not a fixed vendor list.

Improved

• The @ menu lists MCP servers instead of every individual tool, so a handful of servers no longer floods the menu.
• Linux ships as .deb and .rpm packages.
• Cortex is now released under the Apache-2.0 license.
• Project search uses the ripgrep binary already bundled with the app, instead of falling back to a slower search.

v3.0.21 August 29, 2026

New

• New DeepSeek V4 Flash Vision Exp model added. Fast vision-capable tier for screenshots, UI checks, and on-screen reasoning.

Improved

• Optimized agent loop for faster plan, edit, run, and verify.
• More responsive editing, file tree, and model switching.

Fixed

• Bug fixes across editing, file trees, and model switching.

v3.0.12 August 19, 2026

New

• Spreadsheets open natively. .xlsx, .xls, and .csv open in a Sheets-style viewer with tabs, sticky headers, and colors.
• Built-in formula engine. SUM, IF, ROUND, and ranges compute instantly, no Excel required.
• Qwen Token Plan support. sk-sp- keys route correctly; latest Qwen 1M-context models with vision.

Improved

• 5× faster live streaming on long responses.
• Single clean startup splash.
• Office files parse off the GUI thread, large Excel files no longer freeze the app.

Fixed

• Invisible text on light-filled spreadsheet cells.
• Yellow crosshair cursor in spreadsheet preview.
• Spreadsheet preview no longer splits the editor 50/50.
• Tool cards duplicating into a wall of text.
• Ripgrep always falling back to Python.
• Repeated tool calls losing their result cards.
