Nightly Builds are created automatically whenever the Pencil2D source code is updated and are therefore the most up-to-date versions of Pencil2D. They usually contain new fixes and features that have not made it into a stable release yet, however they can also contain new bugs.
We provide Nightly Builds for Windows (32-bit and 64-bit), macOS and Linux (64-bit). However, because these downloads are created in an automated process, it is possible for the build to temporarily fail on some operating systems. In case a certain build is not available for your operating system, please check the preceding builds.
