After four months of intense work and more than 200 commits, Jean-Baptiste Mardelle and the Kdenlive team are happy to announce the release of Kdenlive 19.12.0. This release comes with many changes under the hood, new features and nifty eye candy additions. The highlights include huge performance improvements resulting in a faster and smoother timeline, a new audio mixer, master effects (audio/video), and better audio waveform display to name a few. Not to mention the usual round of stability and usability fixes.
