-Take these with a huge grain of salt,

<h2>Release Planning</h2>
-<h3>Why has 1.0 still not been released?</h3>
-
-<p>
-As seems so common these days,
-SCons has had an extremely lengthy "beta" period.
-The primary goal has been to arrive at something by 1.0
-that we feel is absolutely rock-solid-stable
-and which people can download and use without fear of
-broken builds or unnecessary rebuilds.
-To get some idea of how we do this, see our
-<a href="testing.html">testing philosophy</a> page.
-</p>
-
<h3>Release numbering</h3>
<p>
-Our release numbers are of the form <i>major</i>.<i>minor</i>.<i>sub</i>.
+Our release numbers are of the form <i>major</i>.<i>minor</i>.<i>revision</i>.
</p>
<ul>
<strong>Major release (1.0, 2.0, 3.0, etc.)</strong>
<p>
The major number increments when one of two things happens:
+</p>
<ul>
<li>The release knowingly breaks backwards compatibility in some way.
<li>The release knowingly causes a rebuild when you upgrade.
</ul>
+<p>
Our goal is that as a user of SCons,
you should always be able to upgrade to a later
-revision of the same major number
+release of the same major version
with complete confidence that your build will not break.
+We expect that our major releases will be long-lived platforms
+with many minor releases to add functionality and fix bugs.
</p>
</li>
<li>
<strong>Minor release (1.1, 1.2, 1.3, etc.)</strong>
<p>
-Minor releases will add new functionality to an
-existing major release branch.
-All new functionality will be added so as to never
-knowingly break backwards compatibility with any
-previous minor releases from the same branch.
-We expect that our major release branches will be long-lived
-platforms for delivering many minor releases to
-add functionality.
+Minor numbers increment for releases
+that add new functionality and/or bug fixes
+to an existing major release.
+Any new functionality will never knowingly break backwards compatibility
+with any previous minor releases from the same major release.
</p>
</li>
<li>
-<strong>Bug-fix sub-release (1.1.1, 1.1.2, 1.1.3, etc.)</strong>
+<strong>Bug-fix revisions (1.0.1, 1.1.1, 1.2.1, etc.)</strong>
<p>
-Released whenever a critical bug fix is necessary
+Revision numbers are appended and/or incremented
+whenever a critical bug fix is necessary
for a major or minor release.
+Because most new functionality and bug fixes
+will be delivered in minor releases,
+we expect that there will be few of these—at most
+one per minor release.
</p>
</li>
<li>
-<strong>Testing pre-release (1.1.90, 1.1.91, 1.1.93, etc.)</strong>
+<strong>Release candidates (x.y.z.dyyyymmdd)</strong>
<p>
-A sub-release number of 90 or greater
-indicates the release is intended for
-testing a set of new features intended for
-wider distribution in the next major or minor release.
+A release candidates is a special form of checkpoint
+(see below)
+that is expected to be the next major or minor release.
+If blocking issues show up in the candidate,
+another candidate will normally be issued
+(potentially delaying the release date),
+otherwise the candidate will be repackaged as the major or minor release.
</p>
</li>
-</ul>
+<li>
+<strong>Checkpoints (x.y.z.dyyyymmdd)</strong>
<p>
-Our release numbers are of the form <i>major</i>.<i>minor</i>.<i>sub</i>.
+A checkpoint has a 'd<i>yyymmdd</i>' suffix
+and is made every couple of weeks between major or minor releases.
+It is intended for beta testing new features
+and for ensuring that bug fixes work as intended.
+Although existing features from the previous release will not change,
+compatibility of features under test is not guaranteed between checkpoints
+(<i>i.e.</i>, the implementation of the feature may change).
+Checkpoints are intended not only to allow for wider testing,
+but also to make new features available to users
+(who may urgently need one of them)
+in advance of them being published in the next major or minor release.
