Hashimoto: We rewrote the Ghostty GTK application

Mitchell Hashimoto has written a blog
post about 'fully embracing the GObject type system' with a
rewrite of the GTK version of Ghostty:

In addition to memory management [improvements], we can now more
easily create custom GTK widgets. This let us fully embrace modern GTK
UI technologies such as Blueprint. For example, here is our terminal
window Blueprint file. This has already led to more easily introducing
GUI features like a new GTK titlebar tabs option, an animated border
on bell, etc.

The rewrite is now the default if one builds Ghostty from source,
and will be included in the 1.2 release that is expected in the next
few weeks. LWN covered
Ghostty in January.
