egoist/mygo v0.6.4 on GitHub

Highlights

Images in the terminal through Kitty's Unicode placeholders. Tools that place images this way, like yazi's previews, now show the images instead of boxes of tofu. (#696)
A terminal scroll bar you can drag. It works like macOS's overlay scroll bars: it shows while you scroll or hover, you can drag the thumb or click to jump, and it fades out afterwards. (#679)
Back and forward with swipes on macOS. Touchpad swipes, and mouse side buttons that send swipes (like Logi Options+), now go back and forward in a Router and in apps that read those keys. (#685)
Japanese. MyGo's own controls, editor, dialogs and menus are now translated to Japanese. (#692)

The code editor folds a run of imports, for Go, JS/TS, Python, Rust, C/C++, Java, Kotlin, Swift, C#, Ruby, Lua, PHP, CSS, Protobuf and Zig. (#711, thanks @hyoban)
The code editor now draws bold and italic syntax tokens in bold and italic, as the theme asks. (#707)
MYGO_LDFLAGS adds your own linker flags to mygo build, for example -X values like a crash reporter's DSN. (#642, @HeroSizy)
On Linux, file associations can name a custom x- MIME type, and the package now defines it so file managers recognize those files. (#634, @firede)

Very long lines (minified or generated files) no longer freeze the app when you move the caret. (#584, @Garfielk)
Python code with single-quoted f-strings (f'…') no longer crashes the editor. (#684)
In Chinese and Japanese text, each character now counts as its own word. Word-by-word deleting, moving and double-click selection no longer swallow a whole clause. (#671)

Holding Command while a touchpad scroll is still coasting no longer zooms the font. (#709, @iamvicliu)
Command-click and the hover underline now work on bare filenames like notes.md. (#646, @xierenyuan)
Powerline's rounded caps now fill the whole cell at line heights above 1, matching the prompt background. (#694)
Mouse selection works again in crossterm TUIs (like herdr) over a mirrored session. (#688)
Backspace, keypad and Alt keys now follow the modes the running program sets in a mirrored session. (#689)

Dragging files or data from other apps now scrolls a list when you hold it near the edge. (#607, @zzstar101)
A button that comes back after a route change shows its own colors right away, instead of fading in from another button's. (#697, @zzstar101)
An atomic save (a temp file renamed over a watched file) is now reported as one write, not a delete then a create. If your app watches a directory and treated the delete as "the file is gone", this stops that. (#686)
mygo dev and mygo build no longer generate a TypeScript client for a native UI project just because it has a package.json. They now only do it when the project depends on mygo-runtime. (#700)

Apps no longer start the "AutoFill" helper process. It used CPU and could stall scrolling. Fixed for macOS 26 and macOS 27. (#699, #701)

Popups opened with window.open keep window.opener and postMessage to their opener. (#710)
A navigation replaced by another one is no longer reported as a load failure, and a host name that doesn't resolve is now reported instead of dropped. (#712)
Short labels no longer get cut off with an ellipsis (for example, a four-character CJK button showing "停止翻…"). (#661, @ACAne0320)
Windows drawn without the GPU (MYGO_GPU=0) no longer stay white or freeze on their first frame. (#691)
On Windows 10, flyouts no longer show up empty when their content relies on a material that the system can't draw. (#678)

Fixed a crash when a window is closed from its own native UI, for example by its close button. (#674, @ak4duy)
The first click on a tray icon with an OnClick handler now runs the handler instead of being dropped. (#706, thanks @YangtseSu)
A click that's released while the app is still handling the press no longer leaves the pointer stuck pressed. This happened most with quick touchpad taps. (#633, @firede)
Web views now show through the content around them when frames are drawn without the GPU on X11. (#695)
Fewer cases of GPU windows going blank after their GL context changed. This is a partial fix for #680. (#681)
Two apps starting at the same time no longer corrupt the shared font cache. (#683)

Go toolchain raised to 1.27.3 for a crypto/x509 security fix (GO-2026-6809). (#616, @zzstar101)
The terminal example waits for its window before OnTitle/OnExit run. (#669)
gofmt cleanup. (#672)
