It took a very long time for me to get around to this release. In part because my spare time has gotten very limited, but it's also because there were constantly many new features to be added. Either from contributors via pull requests or for sponsors needing particular functionality. Both are very good and very welcome, but I will do my best not to let the next release become as big!

In the UI the most visible change may be the new Properties dock, which should be a lot more pleasant to work with than the previous solution. A less obvious one bit still very useful is the support for writing import/export plugins in Python. I've written about both of these features in a previous post.

Apart from that there are just too many new features to talk about, so here's the full list of changes:

As with the last new feature release, the above list mentions many people who have contributed new features and fixes to this release. Thanks to everybody for putting in that extra effort!

Finally, if you want to help out by giving me more time to maintain and develop Tiled, consider donating or becoming a sponsor. Your money will count 100% towards my motivation and eventually to reducing my work hours so that I can dedicate significant amount of time to Tiled and maybe even a successor. A big thanks to all who have already donated or are sponsoring Tiled, since you are making this possible!
