Sublime Text 4, build 4200 is out now with some exciting new features, improvements and fixes. We're also announcing some changes to the way plugins will be handled in the future:
Phasing out Python 3.3
Python 3.3 will be phased out over the course of a year, being removed entirely some time after Q1 2026. This will be done in stages, starting with this update adding the "disable_plugin_host_3.3" setting. With the setting enabled all plugins will run under python 3.8.
Upgrading Python 3.8 to 3.13
We will be replacing Python 3.8 with 3.13 in the next development cycle. Plugins targeting 3.8 will instead run on 3.13. This will roll out slowly, initially through a beta program, to ensure a smooth transition.
Supported Platform Changes
Moving to newer versions of Python means we need to drop support for older operating systems. Future versions of Sublime Text will increase the minimum macOS version from 10.9 to 10.13. We will also be ending support for Windows 7, 8 and 8.1; the minimum will be Windows 10.
Python Upgrade Policy
Going forward we will be following an approximately 5 year lifecycle for python versions, aligning with Python's own policy.
Sidebar on the Right
You can now put the sidebar on the right hand side using the "sidebar_on_right" setting.
Toml and Zsh syntaxes
We now ship with built-in support for both TOML and Zsh
Build System Input
Adding "interactive": true to your build systems allows you to provide input to your programs.
Multi-cursor Performance Improvement
While previously having many cursors would grind the editor to a halt, we now stay usable at over 100 thousand.
