esengine/deepseek-reasonix is a coding agent for complex software engineering tasks. According to the GitHub release record, the repository shipped studio-v2.55.0 on October 29, 2026. This update is a release that adds the chat width adjustment feature and fixes the problem of Git Bash not working in the Windows sandbox.
Chat width can now be set within a 30~100% range in 1% increments. The published change notes state the adjustable range and the increment, but they do not explain what the percentage is calculated against, nor which part of the screen the adjustment applies to. The verifiable change, therefore, is that the setting range has become finer-grained, and the release summary does not allow any assertion about the finer details of actual usage.
The second change fixes the problem of Git Bash not working in the Windows sandbox. This can be read as a change targeting the problem that occurred with that combination, but neither the way the fix was implemented nor the scope of its support is present in the provided release information. There is also no basis for concluding that the same fix was applied to other shells or operating systems. The changes the release summary specifically points out are these two items. What can be confirmed is the chat width adjustment and the fix for the Git Bash problem in the Windows sandbox; the scope and effects beyond that are difficult to judge from this information alone.
