Software release policy

• Core Software
  The software release development process includes extensive QA testing. This is necessary to guarantee the stability of the release, which is of a paramount importance. The date for the next software release is thus fixed in advance, and the scope of the release is adjusted according to the development stage.
   
  The upgrade scheme is simple: A major release (release number ending with 0, e.g. 1.10, 1.20) includes everything needed for the vanilla Libera installation. Minor releases (e.g. 1.21, 1.22) include only the things that have changed from the previous release, regardless of whether it was a major or minor. Even digits (1.0x, 1.2x, 1.4x...) designate stable releases, while odd digits (1.1x, 1.3x, 1.5x...) are reserved for test releases or internal development snapshots. Therefore, to install the latest release, the user has to install the major release and all the minors in chronological order. By using ssh/rsh it is possible to automate the process of updating Libera SW. This can be done by the user.
  
• Generic Server
  Generic Server software is released after each major release and covers the functionality of the CSPI. It is released no more than two months after the major release. It is under GPL license. In relation to the Libera Brilliance - Libera Electron Software Release and Libera Bunch-by-Bunch Software Release, there is one Generic Server release each year. The deliverables: CD with the recent Generic Server release plus sources, an updated manual and other documents, and technical support.

Fee

• The latest software release (actually Release 2.00) is the first release for which every Libera user has to pay a fee. The fee is meant to cover the expenses of a dedicated software team, which is obliged to promptly respond to the Libera Wish List requests.
• The fee is not institute-dependent, as it gives every user an equal possibility of active participation in further Libera development and thus in shaping its future. 
• The fee is, however, number-dependent (for Libera Electron and Libera Brilliance the break point is 15 units, but for Libera Bunch-by-Bunch there is no difference). 
• Discounts are foreseen for multi-member subscriptions. Please share your wishes with us, and we’ll tailor the offer to suit your needs. 
• Annual subscription fees for Core Software and Generic Server are valid for 12 consecutive months (not the calendar year).
