The Apache Wicket PMC is proud to announce Apache Wicket $version!

Apache Wicket is an open source Java component oriented web application
framework that powers thousands of web applications and web sites for
governments, stores, universities, cities, banks, email providers, and
more. You can find more about Apache Wicket at https://wicket.apache.org

This release marks another minor release of Wicket $major_version. We
use semantic versioning for the development of Wicket, and as such no
API breaks are present in this release compared to $major_version.0.0.

<OPTIONAL> New and noteworthy
<OPTIONAL> ------------------
<OPTIONAL>
Using this release
------------------

With Apache Maven update your dependency to (and don't forget to
update any other dependencies on Wicket projects to the same version):

<dependency>
    <groupId>org.apache.wicket</groupId>
    <artifactId>wicket-core</artifactId>
    <version>$version</version>
</dependency>

Or download and build the distribution yourself, or use our
convenience binary package you can find here:

 * Download: http://wicket.apache.org/start/wicket-$major_version.x.html#manually

Upgrading from earlier versions
-------------------------------

If you upgrade from $major_version.y.z this release is a drop in replacement. If
you come from a version prior to $major_version.0.0, please read our Wicket $major_version
migration guide found at

 * http://s.apache.org/wicket${major_version}migrate

Have fun!

Apache Wicket Release script
----------------------------
Building a release for Apache Wicket.

This script assumes you are running on OS X, it hasn't been tested on any other
operating systems, and you can bet it won't work on Windows...

REQUIREMENTS:

 - A Java version $JAVA_VERSION configured through the Maven toolchain
 - Maven 3.3.0 (older releases are b0rked, just don't bother)
 - gpg, gpg-agent and pinentry for signing
"

if [ ! $( git config --get remote.staging.url ) ] ; then
    fail "
No staging remote git repository found. The staging repository is used to temporarily
publish the build artifacts during the voting process. Since no staging repository is
available at Apache, it is best to use a git mirror on your personal github account.

First fork the github Apache Wicket mirror (https://github.com/apache/wicket) and then
add the remote staging repository with the following command:

    $ git remote add staging git@github.com:<your github username>/wicket.git
    $ git fetch staging
    $ git push staging

This will bring the staging area in sync with the origin and the release script can
push the build branch and the tag to the staging area.

The release has been created. It is up to you to check if the release is up
to par, and perform the following commands yourself when you start the vote
to enable future development during the vote and after.

A vote email has been generated in release-vote.txt, you can copy/paste it using:

    cat release-vote.txt | pbcopy

You can find the distribution in target/dist.


Failed release
--------------

To rollback a release due to a failed vote or some other complication use:

    $ ./revert-$version.sh

This will clean up the artfifacts from the staging areas, including Nexus,
dist.apache.org and the release branch and tag.


Successful release
------------------

Congratulations on the successful release vote!

Use the release-announce.txt as a starter for the release announcement:

    cat release-announce.txt | pbcopy

A Markdown file called wicket-$version-released.md has been also generated.
You can use it to update the site with the release announcement.

To promote the release after a successful vote, run:

    $ ./promote-$version.sh

This will promote the Nexus staging repository to Maven Central, and move
the release artifacts from the staging area to dist.apache.org. It will
also sign the release tag and push the release branch to git.apache.org

You can read this message at a later time using:

    $ cat release.txt
