  • Clicking the options button in any component will take you to the unified configuration page. Clicking the “Save & Close” button will take you back to the component.\n

  • Joomla 3 is not just about Bootstrap as a cool framework in which to work (which it is), it’s about changing the way developers do components and modules so they can have good looking output that is easily styled in a standard way.\nLESS is an extended framework for CSS allowing for variables, mixins, nested rules, functions and operators. The idea is, among other things, to maximise re-use so that changes global changes can be made in fewer places which are later compiled into regular CSS.\n
  • Google “less compilers” to find a list of apps and/or tools for your operating system.\n

  • Developing and testing with maximum error reporting (set in Global Configuration) cannot be overstressed, including testing installation of your extension.\nTurning on “Log deprecated API” will generate a log file in the normal location listing all the deprecated API that you need to take care of (note, it will be punctuated with calls to JError and JRequest that may not be your fault).\n

  • When upgrading from 2.5, you must change the “Update server” setting in the options for the Joomla! Update component. By default it will keep you on an upgrade path for the Long Term Supported versions only.\n

  • A proposed revision of the current development release cycle in shown. Under the current cycle, 3.5 would be released in September 2013, but this would allow for 6 months of regular bug fixing and possible new, minor feature inclusions (as we saw in 2.5.4 and 2.5.5). The revised cycle allows for a “3.2” to be released in September 2013 and parallel releases of 3.5 and 4.0 in March 2014. This new “3.5” is feature fixed (essentially, whatever the last 3.2.x was) and only receives security and major bugs fixes. This revised approach provides for a more stable platform for users wanting to jump from one long-term-release to the next.\n

    1. 1. Joomla! 3Brisbane Joomla User Group - 19 September 2012Andrew Eddie
    2. 2. Executive summary 3.0.0 due on or about 26 September 2012 Expect some change ‣ an increment in the first number of the version allows for breaking changes ‣ major changes are in the template markup Upgrading the site from 2.5 will be [relatively] easy ‣ but migrating from 1.5 will still be hard Stability comparable to 2.5 ‣ but bugs will still be thrown in for free
    3. 3. New feature highlights
    4. 4. Bootstrap templates (protostar frontend template shown)
    5. 5. Some visual changes but minimal training difference for administratorsbetween 2.5 and 3.0
    6. 6. Refactored UIDrag and drop ordering
    7. 7. Install accredited language packs from within the administrator
    8. 8. Unified global configuration and component options
    9. 9. More feature highlights jQuery in the core sitting beside Mootools Multiple sample data options New Joomla Platform under the hood ‣ Version 12.2
    10. 10. Installation3 simplified stepsPHP 5.3.1+MySQL 5.1+ (InnoDB support required)

    18. 18. Bootstrap Grand vision ‣ A means to an end, but not the end itself ‣ Rich palette of standard UI elements - the visual DNA of a Joomla site ‣ Unifies the frontend and backend experience Why Bootstrap ‣ Popular and widely adopted standard ‣ LESS is more ‣ Responsive grid ‣ Looks great of all the good browsers, oh, and makes IE behave too ‣ Looks and performs great on multiple devices ‣ Templates available outside the regular Joomla marketplaces
    19. 19. For designers Possible to opt out ‣ All the jdoc: tags and PHP are still available ‣ Just need to skin all the styles yourself Icomoon font based icons ‣ 715 possible vector icons that scale and colour easily LESS CSS ‣ Core found in /media/jui ‣ Most customisation in *.less files ‣ Compile and compress your responsibility
    20. 20. For developers Lots to Bootstrap cheat sheets around No need to mess around with custom template styles ‣ For those that can’t help themselves, follow the conventions ‣ Push back changes to the core for others to use
    21. 21. jQuery and Mootools are not the same, but ... Bootstrap runs natively with jQuery ‣ Version 1.8.1 included with Joomla 3 Mootools provided for backward compatibility ‣ Long term goal is to retire Mootools support
    22. 22. Shipped templates Frontend ‣ Protostar (pure Bootstrap) ‣ Beez3 Backend ‣ Isis ‣ Hathor (revised) ‣ Bluestork “maybe” but not out of the gate

    25. 25. And a few more JModel, JView, JController are now interfaces ‣ Use JModelLegacy, etc, instead ‣ Also supported in 2.5.6 to make dual-version components easier to build Legacy and transitional issues ‣ *.toolbar.php (Joomla 1.0 style) no longer supported ‣ Module name must start with “mod_” ‣ Old plugin folder layout will no longer work Session cookie not accessible via JavaScript anymore

    29. 29. Upgrade paths From Joomla 1.5 ‣ No direct path to 3.0 ‣ Must migrate through 2.5 using jUpgrade ‣ http://docs.joomla.org/Migrating_from_Joomla_1.5_to_Joomla_2.5
