This is the first post to the libopenmpt-announce mailing list. From now on, we will post release and security announcements here in addition to the website.


The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt-0.2.8461-beta26 (2017-07-07)

  • [Bug] Possible crashes with malformed PLM and PSM files.
  • [Bug] mktime() and localtime() were used for song date parsing. These functions are not guaranteed to be thread-safe by the standard. Furthermore, some standard library implementations are buggy and may cause the program to abort in out-of-memory situations. These functions are now no longer used.

  • Loops shorter than four sample points at the end of a sample could cause the sample data before the loop to become corrupted.

The changelog for older versions can be found at https://lib.openmpt.org/doc/changelog.html .
