This month was the starting point for the 1.4 release, which is Inkscape last Gtk3 based release before moving onto Gtk4. Many of the fixes in this list have been worked on in a backwards way as we fixed them in 1.4.x first and will forward port them to the main inkscape development later.
The issues we have been working to can be found here: https://gitlab.com/groups/inkscape/-/milestones/13
