- Fix Blender 5.0 API: active_sequence_strip → active_strip, bracket property access on AddonPreferences, _RestrictContext during register() - Fix new_effect() frame_end → length for Blender 5.0 - Fix OTIO adapter kwargs (rate/ignore_timecode_mismatch only for cmx_3600) - Fix OTIO global_start_time RationalTime → int conversion - Add Import STB XML operator with movie strip import and XML patching for Storyboard Pro transitions missing <alignment> - Add Create Sequence Strip operator (select shots → create sequence) - Improve Set Stamps: channel at top, no conflict with existing strips, use raw strip names in templates - TVSHOW episode fixes: sequence loading, episode creation - Kitsu: new_asset, new_episode, admin_connect fix, gazu version pin - Fix escape warnings in file_utils regex patterns - Guard handler registration against duplicates Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
