Synfig Studio full changelog

Feature Enhancements: Several new capabilities have been introduced, such as an angle converter that supports integers, hotkeys for locking/unlocking past and future keyframes, a new 'Alpha Intersection' blending mode, and enhanced palette clipboard functionality. Additionally, initial support for SVG Text elements and Lottie Text Layers has been added.
Stability and Quality Improvements: Numerous bug fixes address critical issues including rendering artifacts in outlines, undefined behavior during undo/redo operations after value conversion, crashes related to malformed PNG imports or null devices, and various UI/UX inconsistencies. Specific fixes include improved SVG importer behavior, corrected bline tool interactions, and resolution of font rendering issues.
Performance and Code Refinements: Significant refactoring efforts have been undertaken, including the porting of several layers (Bevel, Noise gradient, HalfTone2 & 3) to the more efficient Cobra rendering engine. Other improvements include optimizing code for image sequence import, enhancing parameter passing by reference, and general code style cleanups.
