  • 5. Too Long Between ReleasesS  Contributors don’t see code usedS  We can’t keep up with current releases for third-party programs like PHP, MySQL, editors, MooTools, etc.S  The Project is perceived as stagnant 5 Andrea Tarr Joomla!dagen 2012
  • 6. Development Strategy6 Andrea Tarr Joomla!dagen 2012
  • 7. ObjectivesS  To continue to offer a stable and reliable platform for our current and future user base.S  To make innovation available to users and developers on a more timely basis.S  To make it easy for developers to contribute code to the project at any time. 7 Andrea Tarr Joomla!dagen 2012
  • 8. Major PrinciplesS  Maintain a stable trunkS  Predictable, incremental software releases;S  Strong backward compatibility support;S  A sound security policy;S  An open development process. 8 Andrea Tarr Joomla!dagen 2012

  • 10. Predictable, Incremental Software ReleasesS  Move to Timed Releases: Release on specific dates rather than when certain features are all readyS  Contributors can see code released quicklyS  Easier to keep up with other software (PHP, libraries, editors, etc.) 10 Andrea Tarr Joomla!dagen 2012
  • 11. Timed ReleasesS  January 2011: Joomla 1.6.0 (should have been 2.0.0)S  July 2011: Joomla 1.7.0 (should have been 2.1.0)S  January 2012: Joomla 2.5S  Minor releases are released about every 6-8 weeks depending on security issues or major bugs. 11 Andrea Tarr Joomla!dagen 2012
  • 12. Version StrategyS  Major.Minor[.Maintenance]S  This numbering scheme starts completely with series 3S  If we had started with this instead of 1.6, for example:S  1.6.0 = 2.0.0S  1.7.0 = 2.1.0S  2.5.0 = 2.5.0 12 Andrea Tarr Joomla!dagen 2012
  • 13. Major ReleaseS  2.x.x -> 3.0.0S  High degree of changeS  Massive Architectural and/or user interface changesS  Substantial changes to underlying data model 13 Andrea Tarr Joomla!dagen 2012

  • 15. Maintenance ReleaseS  3.0.0 -> 3.0.1S  Fixes to bugs, security vulnerabilities and usability issues onlyS  New functionality is not introduced unless specifically addressing a problem with the previous release that must be handled before the next minor release* 15 Andrea Tarr Joomla!dagen 2012
  • 16. Release Life CycleS  Alpha: Not feature complete, not suitable for production environments, intended for testingS  Beta: Feature complete, not suitable for production environments, intended for testing and bug fixing. New features generally not introduced once we get to betaS  Release Candidate: A beta that will go GA unless critical problems emergeS  General Availability: Stable, ready for mass distribution 16 Andrea Tarr Joomla!dagen 2012
  • 17. Release PhasesS  Maintenance (6 weeks) S  After a release reaches General Availability, it is still the main focusS  Feature Merge (3 months) S  Focus moves to merging new features for the next Minor or Major release.S  Release Testing (2 months) S  Beta period S  Online help documentation and translation strings are finalized S  Third party extension developers should start testing for backward compatibility issues 17 Andrea Tarr Joomla!dagen 2012
