New in this release is that Observatory now always reopens libraries upon launching. Previously this behavior was determined by the “Close windows when quitting an app” setting of the General System Preferences, but since this setting is turned on by default, many users were not aware of this feature in Observatory.
Another improvement is related to the decrease in contrast of successive macOS releases. These changes affected the legibility of inspector, browser and editor labels in Observatory. This has been fixed.
The largest change however is one that becomes relevant only later this year. Observatory is now compatible with Apple silicon! Right now Apple doesn‘t allow us to release a universal binary that runs natively on Apple silicon and natively on Intel-based Mac computers, but Observatory is now compatible with Rosetta 2 translation on Big Sur.
