2025-12-10T22:08:45Z

This release is brought to you with almost 700 commits by the following individuals:

Besides some bug fixes and library improvements, I want to highlight the following changes:

allows easier theming.

Windows, although it currently doesn't update the window settings when
switching between screens with different scaling factors.

Plugin support for the Neovim editor.

Some possible backwards compatibility issues:

The argument order to ltake was swapped to be more consistent with words like head.
The environment vocabulary on Windows now supports disambiguating f and "" (empty) values
The misc/atom folder was removed in favor of the factor/atom-language-factor repo.
The misc/Factor.tmbundle folder was removed in favor of the factor/factor.tmbundle repo.
The misc/vim folder was removed in favor of the factor/factor.vim repo.
The http vocabulary request tuple had a slot rename from post-data to data.
The furnace.asides vocabulary had a slot rename from post-data to data, and might require running ALTER TABLE asides RENAME COLUMN "post-data" TO data;.
The html.streams vocabulary was renamed to io.streams.html
The pdf.streams vocabulary was renamed to io.streams.pdf
