@FBnil the official release on the repo
https://repo.openpandora.org/?page=detail&app=scummvm.djwillis.0001 and the latest version on
https://www.scummvm.org/downloads/ are both the same bar one being the extracted PND and one being a Zip with the README also outside the PND.
The SHA sum for ScummVM.org is based on the ZIP so you can verify the download, not the PND inside of it, but I may include the SHA sum for the PND in the ZIP in future to avoid confusion. It's a good shout.
This release exactly matches the ScummVM 2.2.0 source release as all my changes are in GIT. I have been a member of the ScummVM team for many years now working on other stuff as well as my backend, and also tend to make my release builds available elsewhere like the repo along with odd test builds when I have a change that needs testing, not that I have done much major work on my backends for a few years prior to the last month or so

.
The 2.2.1 release seems to have been taken from the automated buildbot releases from
https://buildbot.scummvm.org/builds.html and I have had nothing to do with its release or sharing elsewhere - those builds are NOT release or optimised builds are are built with an older OpenPandora toolchain of mine (I have not yet updated the old buildbot with the newer toolchain). My view on the buildbot releases is that I have always encouraged the use of them for people that understand they have a lot more debug info and are slower. Ideal if you want to test a fix or an in development engine for instance.
For general users, always take the latest official release from ScummVM.org or the repo.
@levi thanks for the confirmation.
