Mozilla.org: Mozilla 1.0 Manifesto

“People often ask “Why should Mozilla have a 1.0? Why
not just keep going and let vendors pick good milestones
retrospectively?” There are several reasons to do a 1.0, enumerated
below. But let’s agree on what a “Mozilla 1.0” would be:

• The first major-revision-number milestone release (mozilla1.0)
  of the Mozilla browser application suite and platform from
  mozilla.org. A release of higher quality than any delivered so far,
  on whose quality our reputation is at stake precisely because 1.0
  is such a coveted and feared version number.
• A set of promises to keep compatibility with various APIs,
  broadly construed (XUL 1.0 is an API), until a 2.0 or
  higher-numbered major release. All milestone releases and trunk
  development between 1.0 and 2.0 will preserve frozen interface
  compatibility. Mozilla 1.0 is a greenlight to hackers,
  corporations, and book authors to get busy building atop this
  stable base set of APIs.
• A stable, long-lived branch off of the cvs.mozilla.org trunk
  (MOZILLA_1_0_BRANCH). Interested parties should collaborate, with
  support from staff@mozilla.org, in developing conservative fixes
  for critical bugs in this branch. Anyone who wants a baseline for
  development that will work with the public APIs of Mozilla 1.0 is
  free to develop against the 1.0 branch.
