<h1>Releasing a new version of ggplot2</h1>

<h2>Release candidate phase</h2>

<p>After issues resolved for a given release:</p>

<ol>
<li><p>Pass R CMD check.</p></li>
<li><p>In DESCRIPTION and NEWS, remove the .99 version suffix and increment the
version number. For example, 0.9.2.99 becomes 0.9.3.</p></li>
<li><p>Do the same for any packages that ggplot2 depends on, such as scales and
gtable.</p></li>
<li><p>Update ggplot2&#39;s Import dependency versions to use the final release numbers
of scales and gtable.</p></li>
<li><p>Commit these changes to a branch with <code>ggplot2-&lt;version&gt;-rc</code>, and push the
branch.</p></li>
<li><p>Check packages that depend on ggplot2 with <code>devtools::revdep_check()</code> and
run visual tests.</p></li>
<li><p>Email ggplot2, ggplot2-dev, and bcc the maintainers of packages that depend 
on ggplot2 (<code>revdep_maintainers(&quot;ggplot2&quot;)</code>).</p>

<pre><code>Hi all,

We&#39;re very please to announce a release candidate for ggplot2 1.0.0! This
release celebrates the ggplot2 community: all improvements have been 
contributed via pull requests.

We&#39;ve made every effort to make sure that your existing ggplot2 graphics
continue to work. ggplot2 1.0.0 has passed R CMD check, all our existing 
visual tests, and R CMD check on all dependencies. But it&#39;s still possible 
that some bugs may have crept in, so we&#39;d really appreciate it if you&#39;d 
try it out. It&#39;s easy to install the development version: first install 
devtools, then run `devtools::install_github(&quot;hadley/ggplot2@ggplot2-1.0.0-rc&quot;)`.

We plan to submit ggplot2 to cran in two weeks, May 9. Please let us know if 
you have any problems - your feedback is much appreciated. (If you&#39;re pretty
sure you&#39;ve discovered a new bug, please start a new thread or file
an issue on github, otherwise it&#39;s a bit hard to track what&#39;s going on).

Hadley &amp; Winston
</code></pre></li>
<li><p>Notify cran:</p>

<pre><code>Dear CRAN maintainers,

ggplot2 1.0.0 has entered the release candidate phase and will be
submitted to CRAN in two weeks.

Included below is the email that I sent to the ggplot2 mailing and all
maintainers of packages that depend on ggplot2.

Regards,

Hadley
</code></pre></li>
</ol>

<p>If problems arise during the RC period, make fixes on the branch. Those fixes
later get merged back into master.</p>

<h2>Release</h2>

<p>When the package is accepted on CRAN:</p>

<ol>
<li><p>Create a new release at <a href="https://github.com/hadley/ggplot2/releases">https://github.com/hadley/ggplot2/releases</a>.
The tag name should be of the form <code>v1.0.0</code>.</p></li>
<li><p>If any Check out the new branch, or merge it into master. (Need to get off the
rc branch so it can be deleted):</p>

<pre><code>VERSION=1.0.0
git checkout v$VERSION
# Or
git checkout master
git merge v$VERSION
</code></pre></li>
<li><p>Delete the <code>-rc</code> branch, with:</p>

<pre><code>git branch -d v$VERSION-rc
git push origin :v$VERSION-rc
</code></pre></li>
<li><p>Once you push the tag github, travis will automatically build the website.</p></li>
</ol>
