  • Service phase and discontinuation. After release a product is sold and actively maintained; when the vendor discontinues a product or part of it, a service phase begins in which it is no longer sold for new projects or maintained on the vendor's own initiative, and a discontinuation date may follow.

  • Annual service packs. Service packs for CODESYS V3 are released at annual intervals and include improvements and bug fixes, with patch releases in between. [1]
