libopenmpt is a cross-platform C++ and C library to decode tracked music files (modules) [wikipedia] into a raw PCM audio stream.
openmpt123 is a cross-platform command-line or terminal based module file player.
libopenmpt is based on the player code of the OpenMPT project (Open ModPlug Tracker, https://openmpt.org/). In order to avoid code base fragmentation, libopenmpt is developed in the same source code repository as OpenMPT.
Language bindings are available for a variety of other programming languages.

In the mid-90s, Olivier Lapicque wrote the ModPlugin for web browsers, based on his previous Mod95 player. While GeoCities sites were still threatening their visitors with MIDI music and MP3 was not very common yet, this plugin brought the small module files into the world of websites.
Soon, Olivier began working on ModPlug Player. His goal was to spread out tracked music, taking it out of the DOS world, and trying to keep it free. This all-in-one module player quickly superseded the then popular Mod4Win player. It supported a wealth of module formats as well as sound enhancing effects like a graphic equalizer, reverb, bass expansion and automatic gain control. Although its development has been halted (the last version being from 2001), ModPlug Player is still one of the most remarkable (but not necessarily recommended) module players with unique and unmatched features like mixing two modules at the same time, adjusting their pitch and tempo independently, etc...
Shortly after, ModPlug Tracker development started. Together with Buzz, it was the first real tracker software for Windows. The first alpha and beta versions were released in late 1997. While it might have looked a bit different back then, it is still the base of OpenMPT and this is where it all started. ModPlug Tracker evolved over the years, until Olivier decided to release the source code to the public in 2004, so that other people could continue working on it. Previously developed under the name MPT Wild!, OpenMPT is today's most actively developed spin-off of ModPlug Tracker. There are other, mostly personal branches by individuals, for example modplug23, which is the origin of some of the earlier features added to OpenMPT.
But parts of the code have been opened before that. In December 1999, Olivier sent the module-playing parts of ModPlug Trackers's source code to Kenton Varda, licensed under the GPL, to write a plugin for XMMS based on the code. The source code was later released to the public domain, and the mod-playing code was split off into a separate library, libmodplug, maintained as part of the ModPlug XMMS Plugin project. Today, libmodplug comes pre-installed on many Linux distributions and serves as a base for many other players and trackers such as Schism Tracker.
In the following years, both Schism Tracker and OpenMPT progressed further regarding format support and playback accuracy compared to libmodplug. In 2013, the OpenMPT code base was refactored to support building a separate module playback library from the same source code base again. This library is called libopenmpt. In order to avoid possible future source code fragmentation, libopenmpt is, and will continue to be, developed together with OpenMPT itself in the same source code repository.
libmodplug features missing in libopenmpt:
Yes. libopenmpt API and ABI for both, C and C++, are stable since version 0.2-beta1. They will both be supported and provided by future libopenmpt versions.
Programs will continue to build against later versions of the API and programs linked will continue to work with the ABI of later dynamic libraries. In case we add new API and/or ABI functionality, we will increase the minor version number. Libtool and .so versioning is also provided conciously.
The API and ABI of libopenmpt_ext is not stable and subject to change. However, the API and ABI provided by any particular interface ID will stay unchanged. Support for any interface ID may disappear. If changes to an interface are made, a new unique ID will be used.
For editing purposes, OpenMPT converts all formats into one of its five native formats (MOD, XM, S3M, IT, MPTM). libopenmpt does not need to do this, so some inaccuracies that are present in other formats might play just fine.
Furthermore, libopenmpt does currently not support VST plugins. Apart from this, libopenmpt and OpenMPT playback is practically identical.
