إصدار كِدِنلايف 26.08.0

الاثنين، 31 أغسطس 2026  |  فريد عبد النور

#Release  

We are happy to announce the summer release of Kdenlive 26.08. Continuing the efforts from the last version, the core team has been focusing mostly on stability - fixing bugs and crashes while also doing lot's under the hood improvements.

This release comes with 11 crash fixes as well as improvements to the undo/redo stack for compositions and sequence creation. Work has also been done to modernize the codebase in the Qml loader for Clips and Compositions.

The majority of the new, nifty and shiny additions and enhancements in this release were made by new contributors! This seems to have become a tradition in 2026, and we couldn’t be happier about it.
