Following Liferay's official versioning scheme, this release is Liferay Portal 6.2 CE GA4. The internal version number is 6.2.3. Future CE releases of 6.2 will be designated GA5, GA6, .. and so on. See below for upgrade instructions from 6.2.x, 6.1.x, 6.0.x, and 5.x.
You can find the 6.2 CE GA4 release on the usual liferay.com downloads page. If you need additional files (for example, upgrade SQL scripts or dependency libraries), you can find them at the bottom of the downloads page.
Developers can find this release in our Maven repository, and it should be showing up on Maven Central in the near future. As a reminder, you can also find SNAPSHOT releases of Liferay 7!
As Liferay is an open source project, many of you will want to get at its guts. The source is available as a zip archive on the downloads page, or in its source code repository on Github. The repository has also been tagged for the release (as a reminder, the liferay-plugins repo no longer gets tags for portal releases as the plugins are de-coupled from core). Many community contributions went into this release, and hopefully many more in future releases! If you're interested in contributing, take a look at our new participate page on the Liferay Developer Network.
What's New / Changed?
This update fixes many issues [full list here], but here are some of the more important and/or popular ones that you may be interested in:
These are issues that were found during testing, but deemed not a showstopper (usually things are left as-is because they aren't severe (data loss/security breach), don't affect very many people, and there is a convenient workaround - luckily our 6 month cadence means you don't have to wait more than 6 months!). For details on workarounds, see the bug reports.
- Writing to search index fails when Index Writer queue is full (LPS-54672)
- lucene/dump does not work when starting a node (LPS-54876)
The Liferay Documentation Team has been continuously adding and improving on the official documentation. This includes updated javadoc and related reference documentation, updated tutorials and learning paths, and a new home on the Liferay Developer Network. While still in beta, this site will also become the new home of our developer and technical communities.
Our community has been instrumental in identifying the areas of improvement, and we are constantly updating the documentation to fill in any gaps. Check out Rich's blog for more detail on how you can get involved.
Liferay has published the official compatibility matrix for 6.1 and 6.2. This is the official support matrix for our Enterprise Subscription customers, but it's a pretty good reference for CE as well. If you're wondering where Java 8 support is at, it's expected in the next release and has already been added as supported platform for EE.
Most Liferay-authored Marketplace plugins were updated to support 6.2 GA1 when it was first released, and remain compatible with this updated GA4 release.
If you are a Marketplace Developer, and have authored a 6.2 CE GA1, GA2, or GA3-compatible app, you should ensure your app continues to work with this 6.2 CE GA4 release. It is Liferay's aim to remain compatible within a given release family, so in the unlikely event that your app works with GA3 but NOT GA4, you will need to make any necessary changes and re-submit, and let the Marketplace team know about any incompatibilities you discovered. Chances are you will have nothing to do (since you declared compatibility with 6.2.0+, which includes 6.2.3).
As always, the project continues to use issues.liferay.com to report and manage bug and feature requests. If you believe you have encountered a bug in the new release (shocking, I know), please be cognizant of the bug reporting standards and report your issue on issues.liferay.com, selecting the 6.2.3 CE GA4 release as the value for the Affects Version/s field.
Good news for those of you on 6.0 or prior! Liferay introduced the seamless upgrade feature with Liferay 6.1. Seamless upgrades allow Liferay to be upgraded more easily. In most cases, pointing the latest version of Liferay to the database of the older version is enough. There are some caveats though, so be sure to check out the Upgrading Liferay information on the Liferay Developer Network for more detail on upgrading to this release.
Support for Liferay 6.2 CE comes from the wonderful and active community, from which Liferay itself was nurtured into the enterprise offering it is today. Please visit the community pages to find out more about the myriad avenues through which you can get your questions answered, and check out the new Liferay Developer Network for technical resources during your Liferay journey.
Liferay and its worldwide partner network also provides services, support, training, and consulting around Liferay via its Enterprise Subscription.
Also note that customers on existing releases such as 6.0 and 6.1 continue to be professionally supported, and the documentation, source, and other ancillary data about these releases will remain in place.
Of course we in the Liferay Community are interested in your take on the new features in Liferay 6.2 and the updates in this GA4 release. Work has already begun on the next evolution of Liferay, based on user feedback and community ideas. If you are interested in learning more, join our expedition team and see what's under the hood of Liferay 7!
As I mentioned earlier, we will start doing regular open source releases of Liferay Portal every 6 months, until the next major release. So if you find bugs in this or previous releases, and want to up their priority to get them fixed, be sure to use JIRA and vote for your favorite issues!
This release was produced by Liferay's worldwide portal engineering team, and involved many hours of development, testing, writing documentation, translating, testing some more, and working with the wider Liferay community of customers, partners, and open source developers to incorporate all sorts of contributions, both big and small. We are glad you have chosen to use Liferay, and hope that it meets or exceeds your expectations!
In addition to Liferay's engineering staff, a special thanks goes to the many open source developers who volunteered their time and energy to help with the release, whether it was bugfixing, idea generation, documentation, translations, testing, or other contribution that helped to improve this release. Check out the Community Contributor Hall of Fame and be sure to thank them if you run across them in the community (or add your name if you have contributed and are not listed).
