Subject [Cordova Wiki] Update of "CuttingReleases" by AndrewGrieve
Date Fri, 30 Aug 2013 20:50:18 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cordova Wiki" for change notification.

The "CuttingReleases" page has been changed by AndrewGrieve:

  = Apache Cordova Releases =
  
- An official source release contains the source code for the repositories of the Apache Cordova
platform, the signing keys and various checks to prove the validity of the release. 
+ This page describes the technical steps for releasing. For the versioning & frequency
of releases, see: VersioningAndReleaseStrategy.

- == Release Philosophy ==
- 
- The Apache Cordova community aims to prepare releases monthly. Discussion for a release
always happens on the mailing list. 
- 
- We follow a rolling releases (sometimes called the Train Model) philosophy, which is to
say, we value consistent release cadence as a priority over aiming to cram a particular issue,
bug or feature to a particular date. Each minor release tends to be loosely themed on a generally
agreed upon goal for the project. Bugs always take priority over new shiny. 
- 
- Early in the project we stalled on 0.8.0 for almost a year, and as a result our community
worked off the edge, making issue tracking very difficult, cascading into a host of predicability
and reliability issues, jeopardizing the community. In 2009, when IBM joined the effort with
Nitobi, we started releasing once a month, rolling issues over to the next minor.
- 
- We have recently, in the past year or so, started tagging Release Candidates about a week
before the expected ship for minor release (such as 1.5.0rc1) which tends to tease out more
bugs and avoid the embarrassing patch release. (1.4.1 comes to mind.)

-  1. See if there are any changes people are waiting to get in for the release.

-    * Any issues that don't need fixes, bump to the next release.

-  * Make sure the CLI tools (cordova-cli) work with the release. If a platform has modified
structure or contents of platform-specific files, especially the config.xml file, cordova-cli
will probably not work. Take a look at cordova-cli's project parser source files (src/metadata/<platform>_parser.js)
for details on how it manipulates platform projects.
