This is a release of stable v0.9.x branch. As time goes one v0.10.x will introduce breaking changes that require work from users to adjust.
Bugfixes will be merged back in subsequent v0.9.x releases until v0.10 will be out.
Non-breaking features may be merged back if feasible.
Note:
This release contain fix for broken clipping present when editor is combined with Dear ImGui 1.89+
