Is There a New version of Logitech Media Server?

Here's the info from mheger, a long-time Logitech Squeezebox employee. (forums.slimdevices.com)

Logitech Media Server 7.7.3 released

Who would have thought?... We just released version 7.7.3 of the Logitech Media Server software. This is a minor update with most important changes for OSX users:

Improved OSX support: new signed installer, 64-bit preference pane, improved power management handling, support for the upcoming OSX 10.9
Support for Linux versions running Perl 5.16
Improved radio station artwork handling
Fixed several issues with caches
Fixed a memory leak
Several minor bug fixes

See the full changelog for more details.

The latest LMS 7.7.3 files can be grabbed from mysqueezebox.com (or downloads.slimdevices.com)

In fairness, I think it should be pointed out that it was a single person who reported problems at AA. Another person there updated without any problems. I don't think there has ever been a software program created that didn't have an issue for someone, somewhere. Note all of the prior versions are still available and it is easy to revert back to an earlier version if you don't get the results you expect.

Are the older versions still downloadable?

Yes. All prior versions of the software (going back years to the SliMP3 server) are available at downloads.slimdevices.com.
