Kdenlive 25.04.1 has been released, featuring a range of fixes and enhancements. The updates encompass resolving the effect stack layout issue that occasionally hindered access to certain parameters, addressing a crash that occurred when loading multiple clips and switching project profiles, enhancing the speed of audio thumbnail generation, and optimizing memory usage for the automask feature.
The comprehensive changelog outlines several enhancements, including resolutions for audio thumbnail generation, addressing crashes when deleting multiple bin clips, modifications to profiles during clip loading, transitioning from unique_ptr to standard pointers, confirming the python virtual environment is located prior to initiating mask tasks, managing high memory usage of SAM2, AMF checksum adjustments, improvements to the audio mixer volume spinbox, rectifying the release script that was capturing an incorrect version for Kdenlive, enabling the pasting of multi-line text in the notes widget, resolving crashes when moving a single clip from a group or as a standalone clip, and addressing ghost widget and layout concerns within the effect stack.
