- Update to version 5.4.2:
+ Updated languages: c.lang, perl.lang.
+ Updated style-schemes: Adwaita-dark, solarized-light,
solarized-dark.
+ Gutter renderers are now provided a prelight quark for lines
when the pointer is over the gutter.
+ Hover assistants now avoid synthesized motion which is used
much more often in GTK 4 when dealing with crossing-events.
+ Hover assistants will now dismiss themselves when the cursor
moves.
+ GtkSourceMap has reduced how often it needs to do allocation by
ignoring spurious notify::upper and value-changed signals from
GtkTextView's vertical GtkAdjustment.
+ The testsuite has gained some correctness improvements.
+ The Vim emulation's register implementation is now shared
between buffers as it would be expected in Vim.
+ Snippets have gained some robustness improvements including the
ability to simplify results from the snippet parser, more
defensive behavior, and being lazier when possible.
+ Tabbing through focus-positions in snippets will now
immediately jump to the new position if scrolling is required
instead of animating as it results in better placement of
tooltip assistants.
+ Assistants including completion, hover, and interactive
tooltips now reduce how often they request presentation and
position calculation from GDK and ultimately display servers
such as Wayland.
+ Completion windows now take the size of the gutter into account
when calculating their position relative to the parent
GtkWindow so that the typed-text column remains aligned with
typed text in the source view.
+ Completion has gained robustness improvements to do less work
when possible and avoid spinning the frame-clock which could
happen in certain scenarios.
+ Updated translations. (forwarded request 983489 from iznogood)
