# Changelog

## Better MCP Auth + Quality of Life

v0.7.0\
Jan 20, 2026

**Improvements & Fixes**

* MCP server auth is now regularly refreshed instead of sometimes becoming stale.
* Improvements to logging in case of long-running agent tasks.
* Copy-pasting code diffs from the browser now preserves newlines.
* Fixed an issue in the build system which caused a broken build on 0.6.0.

## Faster Shutdown + Pairing Mode Stashing Improvement

v0.5.0.0\
Jan 4, 2026

**Featured Changes**

* Pairing Mode now warns you before stashing when your repo has local changes, so you don't lose track of what's about to happen.
* Quitting Sculptor is now much faster, even if your environment is still building or a background task is running.
* Faster shutdowns in some cases when a scheduled cleanup task was running.

**New**

* You can now run tasks with GPT-5.2 for a stronger default option on complex coding work.
* Pairing Mode can now surface progress during startup steps, so you’re less stuck wondering what’s happening.
* Made the key (Enter vs Cmd-Enter) to send messages configurable.

**Improvements & Fixes**

* More reliable devcontainer lifecycle steps, so setup is less likely to hang or behave unpredictably.
* MCP server auth now works on macOS, so connecting tools is smoother on Apple machines.
* Snapshotting no longer bloats your `.git/objects`, so Pairing Mode stays stable even with large untracked files.
* Clearer warnings when diffs can’t be shown for nested git repos, so you don’t get confusing “null” diff errors.
* Fewer noisy logs during common app workflows, so troubleshooting is less cluttered.
* Better error handling around diff artifact creation, so git-related failures are easier to debug instead of failing mysteriously.
* Fewer unnecessary control plane downloads in common scenarios, so startup can feel snappier.

## Pairing Mode Stashing

v0.4.0\
December 15, 2025

**New**

* Pairing Mode now exposes stashing via a dedicated header button with clearer states, so you can pair more quickly without having to get your git state at parity.
* Now Claude's responses stream in smoothly, word by word, so you can follow changes without jumpy text.
* You can now pick between multiple Codex models to better match your workflow or experiments.

![pairing-mode-stashing](https://3805321663-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjFN3RamrZpFlLcWLQKea%2Fuploads%2Fgit-blob-0e4a14b0089a97f2e76989d0f6db84440526f449%2Fpairing-mode-stashing.gif?alt=media)

**Improvements & Fixes**

* Deleted tasks now stay deleted and no longer pop back into your sidebar after their environments finish building.
* MCP server authentication now works properly on macOS, unblocking MCP-based tools on OSX.
* Nested git repositories now show a clear warning when diffs aren't supported, instead of failing with a confusing could not access ?/null error.
* When your saved default or last-used model name is no longer valid, Sculptor now falls back to a supported Claude model instead of failing.
* Pairing Mode and other long-running operations benefit from reduced memory leaks.
* Docker containers and volumes are cleaned up more appropriately.
* Snapshots are smaller by skipping unnecessary git packfile updates, which helps reduce local disk usage and keeps backups lighter.
* Shutdown and environment cleanup now better coordinate container removal with task deletion, reducing leftover containers after you clean up tasks.

## Suggestions On By Default + Smarter Branches

v0.2.35\
December 01, 2025

**Featured Changes**

* Suggestions are now on by default. Suggestions surface potential issues across agent-generated changes so you can review in parallel without getting overwhelmed. If you prefer a quieter workspace or want tighter cost control, you can turn Suggestions off anytime in Settings.

![suggestions-demo](https://3805321663-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjFN3RamrZpFlLcWLQKea%2Fuploads%2Fgit-blob-f507326617c55d5413eba8ea355eeb8db8ce319a%2Fsuggestions-demo.gif?alt=media)

**New**

* Branch dropdowns now show all branches in your repo with search and infinite scroll, instead of only the most recent branches.
* Pairing Mode now displays each step of the on/off process, making it clear what the agent is doing and why.
* You can now run the `/compact` Claude Code slash command directly in Sculptor chats to shrink long or noisy context.
* Devcontainer `forwardPorts` are now respected, so web apps running inside your devcontainer are reachable from your host without extra manual wiring.

**Improvements & Fixes**

* In Pairing Mode, buttons stay in sync across the app, and a live progress popover appears while pairing or unpairing.
* Huge task logs no longer consume excessive memory; errored and overnight tasks stay responsive, and environment startup avoids failures caused by missing or disappearing files during agent creation.
* Branch selection now shows all of your branches (instead of the 5 most recent) and includes a search field to help you find the right branch.
* Slash commands correctly support arguments like `/compact` and sort commands in a clearer order with explicit project/user labels.
* Sculptor remembers your last-used model when you haven’t set a default, and Codex usage reports token consumption more accurately.
* Linux users get the File menu restored, `Ctrl+Enter` sends chat messages, and general UI interactions across the app are more intuitive.

## Smaller Snapshots + More Reliable Tasks

v0.2.32\
November 24, 2025

**Featured Changes**

* Cleanup scripts run in background to garbage collect unused sculptor docker volumes.
* Task containers snapshotting is no longer bloated by git garbage collection for long-running agent environments.

**New**

* Imbue's suggestions agent can now flag "abstraction violation" issues, catching code that reaches into private internals across modules instead of using proper public interfaces.

**Improvements & Fixes**

* Disabled Git's background garbage collection inside containers to avoid surprise slowdowns during long tasks.
* Improved the interactability of the autoupdate notification in future updates.
* Fixed crashes when rsync hits Git's Unix socket files.
* Made Sculptor resilient to bad or empty `docker stats` output caused by old docker versions, avoiding rare frontend startup failures.
* Force certain to run under bash so scripts using `source` and bash-specific syntax behave consistently in cases where the default shell is sh.
* Automatically prune old control plane Docker volumes to free disk space while keeping recent versions.
