Release Policy

Releases

The MOSEK version numbering consists of four numbers major.minor.build.revision (until major version 8) or three numbers major.minor.revision (from major version 9). For example version 9.0.73 has the major version number 9, the minor version number 0 and revision 73.

  • Major version: A new major version contains new features, major enhancements and performance improvements. Moreover, supported platforms and tools, e.g. Java version, can change in a major release. Some incompatibilities with previous versions can be expected.
  • Minor version: A new minor release contains new features and efficiency improvements. Compatibility with the previous releases of the same major version has high priority.
  • Build number: Existed until major version 8 but was mostly unused.
  • Revision: A new revision includes bug fixes and in some cases new functionality. Fully backwards compatible with existing releases of the same minor version. New revisions are released frequently.

This implies that all versions with the same major version number behave almost identically. In general it is safe and easy to upgrade to a newer version with same major version number. Some work can be expected when upgrading to a new major version but performance improvements can be expected. See release notes on the documentation page.

MOSEK supports a major version at least 2 years after the next major version is released. For instance MOSEK version 8 is supported at least 2 years after the initial release of MOSEK version 9. For versions without active support no new releases of the software are issued.
