Aegisub 3.5.0 adds video panning and zooming, much better High-DPI support, prompts to keep a script's resolution and color matrix in sync with its video, a reworked video position marker in the audio display, and native Apple Silicon builds, along with many fixes. Windows and macOS builds are now signed.
The changelog can be found here.
Security: This release fixes CVE-2026-92705: opening a crafted subtitle file could run arbitrary code through Automation scripts it references. All users should upgrade. Thanks to shavitush for reporting it. This release also hardens Aegisub against other maliciously crafted files.

It’s been a while!
This release, the first stable in a decade, was designed to have minimal feature changes from 3.2.2. The goal was to just cut a release that builds on modern systems, which was itself more than enough work. Further releases will include actual features and more normal changelogs. The version is 3.4.0 to avoid conflicts with forks that tagged things under 3.3.x.
Moving forward, development will continue out of TypesettingTools/Aegisub. arch1t3cht has done a great job of running the primary fork used over the past few years, and now has commit access in TypesettingTools so that he can work out of a more centralized repository. We’d love to get all the work done across various forks back into the mainline repository, so please send PRs!
32-bit has been dropped, and while this release runs on Windows 7 that requirement will probably be bumped to Windows 10 for following ones.
By default, the installer does not install DependencyControl, but it is available under the dropdown by selecting “Full installation”. For anyone unfamiliar, DependencyControl offers a simplified way to install automation scripts from a variety of repositories in Github. Many users may not want or need that functionality, especially considering it slows down startup, but it is available for advanced users.
MacOS
Notably missing from this release are signed and notarized MacOS binaries. This is because Apple refuses to let me into the Developer Program and will not explain why. I’m not going to spend any more time fighting their bureaucracy, so if you like MacOS binaries that work on Sequoia please consider:
- Very politely emailing tcook@apple.com and asking that they figure this out
- If you know an Apple employee, very politely asking them to open an issue internally
For any Apple employees reading this, if you’d like to help and need more personal information, please shoot me an email (which can be found on my Github profile).
I am not interested in making an LLC to apply with, or signing binaries under anyone else’s name. If Apple wants to block a random US citizen from producing builds that run on their operating system and not even tell them why, I will not be working around their decision; they can fix their process.

Extra notes for distros
The build has been swapped to Meson. There are fewer vendored dependencies than before, which should hopefully make life easier, but a couple still exist. If you encounter problems with the Meson build, please open an issue or email me. It’s been used for builds out of the AUR, but otherwise it’s more battle-tested on Windows and MacOS.
Aegisub can’t be built with LTO.
Remember that you must build against LuaJIT in 5.2 compatibility mode. Failing to do so will cause many issu

- Update Spanish, Ukrainian, Hungarian and Finnish translations
- Skip writing the Aegisub project stuff when exporting to ASS
- Fix some ugliness in the OS X icon
- Update the selection and scroll position after opening subtitles from video
- Fix crash on a certain kind of malformed shift times history file
- Don't set the YCbCr header field to "None" when resampling resolution without changing colors
