gtksourceview3 was superseded in 2018 by gtksourceview4 (a new major
upstream release, but still using GTK 3). There's a porting guide here,
which is mostly "stop using deprecated APIs" plus a few function renames:
https://gnome.pages.gitlab.gnome.org/gtksourceview/gtksourceview5/porting-guide-3-to-4.html

That porting guide is for C code, but the function renames required to move
from gir1.2-gtksource-3.0 to gir1.2-gtksource-4.0 are probably very similar.

gtksourceview3 is unmaintained and hasn't had an upstream release for more
than 5 years, so it would be great if the remaining gtksourceview3
applications can move to gtksourceview4 before trixie.

gtksourceview4 has itself been superseded by gtksourceview5, which is
for GTK 4 applications. Ideally GTK 3 applications should move to GTK 4,
but that's a larger and more intrusive change. Porting guide:
https://docs.gtk.org/gtk4/migrating-3to4.html,
https://gnome.pages.gitlab.gnome.org/gtksourceview/gtksourceview5/porting-guide-4-to-5.html

Changes:
 formiko (2.0.0-1) unstable; urgency=medium
 .
   * New upstream release (2.0.0), a major rewrite ported to GTK4,
     libadwaita and GtkSourceView 5 (Closes: #1079410):
     - Replace WebKit2GTK 4.1 with WebKit 6.0 (GTK4)
     - Replace gtkspell3 spell checking with libspelling
     - Drop recommonmark in favour of built-in Markdown handling
     - Add jsonpath-ng runtime dependency
     - Add optional neovim (vte), spelling and extra-writers integration
   * debian/control:
     - Bump debhelper-compat to 14, Standards-Version to 4.7.4
     - Add Rules-Requires-Root: no
     - Add dh-sequence-python3, dh-sequence-single-binary and
       python3-pytest to Build-Depends, required with compat 14
     - Add python3-gi, gir1.2-adw-1, gir1.2-gtksource-5 and
       gir1.2-webkit-6.0 to Build-Depends: the upstream pytest suite
       imports them at collection time, which a clean sbuild chroot
       caught but an already-populated dev machine did not
     - Refresh Build-Depends/Depends/Recommends/Suggests for the GTK4
       rewrite (gir1.2-gtk-4.0, gir1.2-adw-1, gir1.2-gtksource-5,
       gir1.2-webkit-6.0, python3-jsonpath-ng, gir1.2-spelling-1,
       gir1.2-vte-3.91, python3-m2r2, python3-pygments, python3-pynvim)
     - Drop the X-Python3-Version field (lintian
       drop-python-version-declaration)
   * debian/rules: simplify to compat 14 style (execute_after_dh_install),
     run the upstream pytest suite during build (dh_auto_test)
   * debian/copyright: refresh copyright years, add Upstream-Contact
   * debian/patches:
     - Drop webkit4.1.patch, obsoleted by the upstream rewrite of
       formiko/renderer.py
     - Add appstream-id-consistency.patch to align the desktop entry
       and metainfo file basenames with the AppStream component id
       (cz.zeropage.Formiko), fixing appstream-metadata-validation-failed
