Lyrion Music Server

Lyrion Music Server is the server software that powers audio players from Logitech (formerly known as Slim Devices), including Squeezebox 3rd Generation, Squeezebox Boom, Squeezebox Receiver, Transporter, Squeezebox2, Squeezebox and SLIMP3. The LMS server also powers various open-source clients using the same protocols.

Before version 9.0 LMS was known as Logitech Media Server, and before 7.7 LMS was known as Squeezebox Server (version 7.4 to 7.6) and SlimServer (before 7.4). Version 7.7 was the last version released by Logitech, from version 7.8 and onwards LMS had been released by the LMS Community.

Lyrion Music Server is Open Source Software and written in Perl. Lyrion Music Server runs on pretty much any platform that Perl runs on, including Linux, Mac OSX, Solaris and Windows.

Sourcecode can be found on Github:

Version history

LMS 9.0

Currently in development. This version will be the first release using the new name Lyrion Music Server! This version is undergoing major refactoring because of the name change and is thus not suitable for usage unless you are prepared to deal with occasional breakage.

  • Massive upgrade for Classical music lovers; this version adds support for works!

LMS 8.5

Current stable. Initially released on March 14, 2024.

This is the last Logitech branded release. It's main change compared to the previous version is the removal of all integration.

Release notes, Announcement

LMS 8.3

Initially released on Nov 4, 2022.

Logitech Media Server v8.3.0 is mostly a maintenance release without any major new features. Oh, hold on... unless you're a Mac user! Apple provided a good reason to get LMS v8.3.0 out: macOS 13 Ventura removed the Perl version we've relied on for about a decade. So, the new feature is:

  • Support for macOS 13 (native Apple Silicon as well as Intel)

But there are a ton of changes, smaller or bigger. A few noteworthy changes:

  • Updated French, British English, Czech, and Dutch translations.
  • Improved indexing performance for the Fulltext Search of large playlists (thousands of tracks).
  • Improved security for the integration.
  • Improved JavaScript support for the Settings pages in the Classic/Light skin (and thus Material).
  • More robust https streaming for some very long (but finite) streams and larger files (hires).
  • Removal of video/picture support.

Other important changes are the removal of PowerPC, Sparc, i386 (Mac), and really old Perl versions are no longer part of the builds.

Release notes

LMS 8.2

Initially released on Aug 3, 2021. This release comes with a lot of improvements, not big new features. But many of them address long standing pain points. Some of the highlights are:

  • Improved podcast support (search, more robust playback)
  • Improved online music integration (smarter matching of artists, track stats support)
  • Improved shuffling method to give more "balanced" results
  • Add Balance setting for players which support it
  • Improved robustness for online streams
  • Add resampling for Ogg/Flac streams

Release notes

LMS 8.1

Initially released on Dec 23, 2020, LMS 8.1 brings the following changes:

  • Support for Deezer lossless (FLAC) streaming
  • Improvements to the transcoding framework to allow protocol handlers to enforce transcoding (eg. TIDAL lossless)
  • Support for macOS 11 Big Sur and Apple Silicon (M1 CPU - using Rosetta)
  • Optionally allow installation of plugins which were targeted at Logitech Media Server 7.*

Other important changes are the removal of the ReadyNAS NV/Duo/Pro devices, and Perl 5.8 in general. We actually broke Perl 5.8 compatibility somewhere around LMS 7.9.3. These platforms haven't been working correctly since then. Removing them thus doesn't really change anything. ReadyNAS users please note: this is really only about the old, legacy, generation 1/2 Raidiator v4 based devices. Any recent ReadyNAS unit, which was based on Debian, should still continue to work as before. Good or bad.

Release notes

LMS 8.0

Initially released on Nov 22, 2020, LMS 8 adds a lot of improvements for users of online music. But there's more:

  • Import your online music library to your music library. No matter whether your favorite album or artist is stored on your disk, or on some music service - it shows up right where you expect "your music" to be.
  • https is the new http: most web sites nowadays are delivered over the secure https protocol. And so are more and more online music streams. Logitech Media Server 8 allows you to continue to listen to your favorite stations, as well as music services like TIDAL.
  • Allow to paste TIDAL and Deezer web links to the Tune In field (or use the corresponding CLI command) to play those items.
  • Plugins now can use SOCKS to access online sources.
  • Helper applications (faad, flac) have been updated, as well as some of the Perl libraries, like Audio::Scan (not all supported platforms).
  • Docker is everywhere. A Logitech Media Server image is now available on Docker Hub.
  • Updated translations for Swedish and Dutch.

Release notes

LMS 7.9

Initially released on Mar 8, 2017. LMS 7.9 comes with lots of improvements, both under the hood as well as in your preferred user interface:

  • Fulltext search
  • Native support of DSD
  • Customizable browse modes
  • Direct access to other source (LMS or UPnP)
  • Playback of local tunes without adding them to the library
  • Filtered views

Release notes
