I have just released XEphem 4.2.0.

The change log:

• Elwood himself has contributed a new option that lets you switch XEphem from giving your telescope J2000 coordinates to giving it equinox-of-date coordinates.
• Sky View: the mouse wheel now zooms the view in and out.
• Sky View: DSS image download has been fixed by upgrading to HTTPS, and the window should no longer awkwardly resize once the image arrives.
• Data ? Download: added the URL of the Celestrak “visual.txt” file.
• Data ? Download: replaced “” with modern HTTPS.
• Data ? Field Stars: Fran?ois Meyer added support for the ucac5 catalog.
• The precession formula has been updated to the one from the 2000 Astronomical Almanac.
• A couple of compilation problems on modern Mac machines have been fixed.
• XEphem now uses more modern SSL setup routines if the code detects it’s being compiled against OpenSSL ≥1.1.
• Closing the INDI window with your window manager’s “Close” button no longer crashes XEphem.
• All references to “” have been changed to their new hostname “”.
• A few other small fixes.

I apologize for allowing so much time to pass since the previous release! Over 2022 there were several email threads that were gradually working on the problem of how to compile XEphem successfully on macOS. Unfortunately, I decided to wait to see if they would reach a perfect answer for all versions of macOS, and wound up waiting far too long — they all petered out without my understanding which versions of macOS needed what. From now on I will instead focus on making more frequent XEphem releases, and as macOS folks report on their various troubles, we can hopefully iterate towards a Makefile that works for everyone.

Now that we have a fresh release to work from, I’ll plan to go back through the open issues and pull requests and make comments and updates where it’s warranted. Enjoy!
