Joomla! 3.5 Release Candidate 2 Released

The Joomla! Project is pleased to announce the availability of Joomla! CMS 3.5 Release Candidate 2. Community members are asked to download and install the package in order to provide quality assurance for the forthcoming 3.5 release.

Joomla! 3 is the latest major release of the Joomla! CMS, with 3.5 the sixth standard-term support release in this series. Please note that going from 3.4 to 3.5 is a one-click upgrade and is NOT a migration. The same is true is for any subsequent versions in the 3 series of the CMS. That being said, please do not upgrade any of your production sites to the release candidate version as a release candidate is ONLY intended for testing and there is no upgrade path from a Release Candidate.


What is this release for?

This is a RELEASE CANDIDATE release, that should only be used on test sites. Release Candidate releases cannot be upgraded. Please note that you cannot upgrade from previous beta releases to this release.

Extension and template developers are encouraged to work with this release in order to prepare extensions for the stable release of Joomla! CMS 3.5, though there shouldn't be any backward compatibility issues. Users are encouraged to test the package for issues and to report issues in the Joomla! CMS Issue Tracker. Please do not upgrade any of your production sites to the Release Candidate version and do not start a new site on Release Candidate as a Release Candidate is ONLY intended for testing and there is no upgrade path from a Release Candidate.

Which bugs have been fixed in Joomla! 3.5?

A full list of issues resolved can be found on Github.

What’s new in Joomla 3.5

The big question is, what is new in Joomla 3.5? We have the following possible features:

Update emails plugin by Nicholas Dionysopoulos

Joomla! issues bug fix and security updates every few weeks. However, many (most?) of its users are completely unaware of this fact unless they log in to the back-end of their site and notice the update nag message at the top. This PR adds a plugin which periodically checks for updated Joomla! versions and, when one is found, emails the Super Users of the site to remind them.

Plugin to gather basic anonymized data as an opt-out feature by Don Gilbert

In order to better understand our install base and end user environments, this plugin has been created to send those stats back to a Joomla controlled central server. No identifying data is captured at any point.

One of stated goals for the last couple of years has been to try to understand our users better. In line with that goal, we want to better understand the sort of environments and platforms that people are using to install and run Joomla. This will enable us to make more informed decisions about which platforms we need to support, minimum version requirements, the pace at which we can encourage people to upgrade, and so on.

In order to gather this information we will be including a new plugin with the Joomla 3.5 release that will automatically gather some very basic data points, noted below. This plugin will be enabled by default, but can be disabled at any point in time. A post-install message will be shown to make site owners aware that the plugin has been installed and will include instructions for disabling it.

The privacy of all Joomla users is important to us and we want to allay any fears that we are collecting personally identifying information. The source code for both the plugin and the server code that gathers the data can be seen in our GitHub repositories and The plugin configuration screen will also show exactly what information is being shared by the plugin.

Access to the raw data collected will be restricted. Only statistical results extracted from the data will be published on the website. Categories with small numbers of entries will be gathered into an "Other" category. The unique id used to prevent duplicate entries will be carefully generated to ensure that it cannot be used to deduce the identity of any individual site. These measures should ensure that individual websites cannot be identified from the published data.

The plugin will collect anonymously the PHP, Database Type and Version and Joomla Version a user is running so that the project can set PHP and MySQL versions more accurately for future Joomla Versions.

Ability to add a user CSS file to Protostar by Roland Dalmulder

Download system/environment information by Radek Suski and Roberto Segura

Implementing a possibility to download system/environment information for support purposes.

TinyMCE drag and drop images by Dimitris Grammatiko

Adds the ability to drag and drop images into the tinyMCE editor that comes with Joomla.

Backwards Compatibility break

We have a backwards compatibility promise to make sure code doesn’t suddenly break. However there are circumstances that can force us to no longer keep this promise. In Joomla 3.5 this is the case. Due to changes in PHP 7, we had to rename the String class to StringHelper otherwise Joomla! cannot run on PHP 7. This is a very minor change and we don’t expect any issues from it. For those interested, you can read more about it at Update to String package 1.3.

A note on routing

The new routing system will not be merged into the 3.5 release. The routing has since been merged into the Joomla 3.6 branch due to a lack of testing before the first 3.5 Beta. The production leadership team understands that the change in features can be disruptive and is an inconvenience to the developers expecting new routing we are truly sorry.

The Joomla! Bug Squad is one of the most active teams in the CMS development process and is always looking for people (not just developers) that can help with sorting bug reports, coding patches and testing solutions.
