Guidelines on API Changes

• Always try to maintain API compatibility.
• If an interface must be changed, try to maintain the old interface for at least one minor version (e.g. 0.10 → 0.11) change and log deprecation warnings when it's used. Document the API change in TracDev/ApiChanges/<version>.
• If the old interface can't be maintained, document it as such in the appropriate TracDev/ApiChanges/<version> Wiki page.

Development Milestones

Milestone 0.13

• [10189]: db API refactoring, using the with keyword (DatabaseApi#Trac0.13API)

Milestone 0.12

• [9595]: 0.12b1
• [9260]: templates/macros.html deprecated
• [9224]: zero-padding of revision numbers in the repository cache (upgrade needed)
• [9210]: timestamps stored as bigints (microsecond resolution) in the db (upgrade needed)
• [9175]: MultiRepos merge, (repository resync needed)
• … (well, tons of changes)
• r7705: i18n support for plugins - you'll need Genshi's ​advanced-i18n for getting translated templates.
• r6986: Internationalization support

Milestone 0.11

• r6805: functional tests available in trunk (see TESTING-README)
• r6572: enabled the "noConflict" mode for jQuery, so that other Javascript libraries using '$' in a special way can be used. As a result, plugins using jQuery should be updated (follow the advice in ​http://trac.edgewall.org/changeset/6572#file11). Whether this change will stay or be reverted is under discussion. update: well, the change has actually been reverted without much discussion in r6715.
• r6352 removed the req.warning("...") call. Replace it with add_warning(req, "...").
• r6139 integrated the API changes developed in the context-refactoring branch. The early 0.11dev plugins most probably need to be adapted. See the TracDev/ApiChanges/0.11 page.
• r5514: Flexible permission system
• r5378: Flexible/extensible ticket workflow
• r4819: Setuptools integration
• r4095: WebAdmin integration
• r4561: versioncontrol "blame" support
• r3947: ​jQuery integration
• r3935: Timezone support and internal use of datetime
