Lançamento do Kdenlive 26.08.0

Segunda-feira, 31 Agosto 2026  |  Farid Abdelnour

#Release  

Temos o prazer de anunciar o lançamento de verão do Kdenlive 26.08. Dando continuidade aos esforços da versão anterior, a equipe principal concentrou-se principalmente na estabilidade — corrigindo bugs e falhas, ao mesmo tempo em que realizava diversas melhorias internas.

Esta versão traz 11 correções de falhas, bem como melhorias na pilha de desfazer/refazer para composições e criação de sequências. Também foi realizado um trabalho de modernização da base de código no carregador QML para Clipes e Composições.

A maioria das novas adições e melhorias desta versão — todas muito bacanas e atraentes — foi realizada por novos colaboradores! Isso parece ter se tornado uma tradição em 2026, e não poderíamos estar mais felizes com isso.
