Observatory 2.1.4 has been released to the Mac App Store.
Observatory 2.1.3 has been released to the Mac App Store.
Observatory 2.1.2 has been released today. Its documentation and release notes once again are searchable from the Help menu.

Observatory 2.1.1 is now available on the Mac App Store.
It contains a workaround for a regression Apple introduces in upcoming macOS Sequoia 15.2 that affects the thumbnail generation by Observatory’s Quick Look extension. Also fixed is an issue with the Quick Look preview image scale overlay.
We are excited to announce that Observatory 2.1 is fully compatible with macOS 15 Sequoia, which Apple is releasing today. Apple always introduces regressions in new major macOS releases, and this one is no different, but after testing Observatory 2.1 with the release candidate we found no more issues with it or its Quick Look and Spotlight extensions.
Observatory 2 requires an Observatory 2 license in order for it to run on macOS Sequoia. Observatory 1 is not supported.
