Introduction

Almost every month we release a new version of Launchpad with the latest features and bug fixes.

We use Launchpad milestones to target work for these releases. You can see what we have planned for each release by visiting the milestones page for the Launchpad project group and viewing one of the upcoming milestones.

Finding the current release and build numbers

Depending on which Launchpad environment you're using, there are two ways to find out which version number and build is running.

On production Launchpad, you need to view the source code of the page. At the very end, you'll find the version and build numbers.

Finding the release number on production

If you're using edge or staging, the version and build numbers are show in the footer of each page.

Finding the release number on Edge

In the screen shot, you can see that release 10.01, build 8939 is running on Edge.

The difference between build and release numbers

Each release represents a certain set of features and fixes that the Launchpad community have worked on and made available in Launchpad production. In effect, a release number is a collective reference for all the features and fixes that the community hope to release at that time.

The build number is taken from the number of the most recent commit to the Launchpad code base running in that environment (e.g. production or edge). This number is more tied to the implementation of the features and fixes. So, while the release number may stay the same, if there's an urgent bug fix or similar, the build number could feasibly change between releases.

If you discover a bug in the Edge version of Launchpad, providing the build number in your bug report may help the Launchpad team.

Release numbering

Our release numbers are easy to understand and follow a similar format to Ubuntu release numbers. The first part of the number is the year in which the release was made and the second part of the number is the number of releases so far that year.

Let's take a look at an example:

Understanding Launchpad release numbers

The older style of release numbering

Previously, Launchpad releases were numbered using a different scheme.

Understanding Launchpad release numbers

Major release: this is the first integer in the old-style release number. This number increased at each major new version of Launchpad, particularly when there was a significant change in functionality or the underlying structure.
Minor release: the second integer. This represents an incremental change in functionality or structure. For example: we moved from 1.1.x to 1.2.x with our January 2008 release.
Individual release: the third integer. This changed with each roll-out of new Launchpad code.

Release announcements

With every release, we tell you what's new in a release announcement posted to the launchpad-users mailing list and the Launchpad News blog.

Our release numbers are easy to understand and follow a ''similar'' format to Ubuntu release numbers. The first part of the number is the year in which the release was made and the second part of the number is the number of releases so far that year.

- * '''Major release:''' this is the first integer in the release number. We increase this number when there's a significant change in functionality or the underlying structure.

-Line 47:
+Line 56:
- * '''Individual release:''' the third integer. This changes with each roll-out of new Launchpad code. Right now, we release a new version once a month, although this number doesn't necessarily tie up with number of the month.

We don't use release candidate numbers.

== Build numbering ==

If you need to know which version of Launchpad you're using, you can take a look at the release number.

However, if you're using our [[BetaTesting|Edge environment]], it may be helpful to know the exact build you're using. On Edge, the build number changes almost every day. On standard Launchpad, it rarely changes more than once per release.

If you discover a bug in the Edge version of Launchpad, providing the build number in your bug report may help the Launchpad team.
