Construct Animate r420.2

Notes

The new sprite sheet import dialog in r420 worked in development, but we were caught out by a crash bug that was caused by the build system and only happened after the release. We've now corrected this issue and this patch release should fix the problem so the new dialog works correctly. We also had time to add in extra toolbar options to set the number of rows and columns, which act as shortcuts to set the image size to extract.

In case you missed it, see the r420 release notes here.

Please note: this is our last planned beta release of the year. The team will be taking a well-earned break over the next couple of weeks, during which time there will not be any beta releases and support may be limited. We'll be back to normal in early January.
