Notes
We did a mid-week release last week, so there's only a small number of changes in this release.
The main improvement is to image recompression on export. You can enable this when exporting to losslessly compress your image files as much as possible to save on the download size. Previously this used an asm.js version of PNGCrush. We've replaced it with a WebAssembly build of OptiPNG instead. The main advantage of OptiPNG is it can do palette reduction. This means it automatically identifies images with 256 colors or less, and recompresses them as 8-bit PNGs instead of 32-bit PNGs, which can be significantly smaller. This is especially effective for pixel art games, since they tend to use a low number of colors. For example we found Demonoire's images are about 33% smaller after recompressing with OptiPNG compared with the old PNGCrush. Also, as with anything upgraded from asm.js to WebAssembly, it's smaller and faster to run too.
As ever there's a few bug fixes too, including a notable fix for using local folder saves in Chrome, which could potentially corrupt the project if it used bundled addons. Thanks to @Rilem for helping us find and fix this!
