Joomla! 3.10 and Joomla! 4.0 support

Today, we are pleased to announce the availability of SEBLOD 3.21.0.

# Key updates:

• Compatibility/support changes for Joomla! 4
• "No Result" file can now be triggered for multiple (> 1) results, useful when a single (unique!) result is required

# Joomla! 4 support?

• No, SEBLOD 3.21 is intended to be used on Joomla! 3.10
• Yes, SEBLOD 3.21 brings required changes to allow a future upgrade from Joomla! 3.10 to Joomla! 4.0
  (once SEBLOD 4.0 GA will be released)

# When and how to update?
Feel free to update now your existing websites to Joomla! 3.10 and SEBLOD 3.21

1. if your website is not already on SEBLOD 3.20.x, please try to do so as the 1st step
2. then update to Joomla! 3.10
3. then update to SEBLOD 3.21

The next ones are only for testing purposes (if you wish to have a try on Joomla! 4)

1. follow the 3 previous steps
2. copy your site to a dev/test environment
3. then update to Joomla! 4.0
4. then update to SEBLOD 4.0-rc2 [GitHub link]

Feel free to check both 3.21 changelog and 4.0-rc2 changelog.
A few add-ons and plug-ins will be updated on the store in the next days (featuring the same changes applied to the Core package).

Please note that the 4.0-rc2 is mainly to show progresses, that there are a few known issues (uncompleted or not merged core changes), and a bit of styling/layout (Bootstrap 5 / jQuery 3) that requires a few additional fixes, but in the meantime... you will see that we already have an up & running Joomla! 4 version of our SEBLOD Demo: demo.seblod.com/joomla4
(not all extensions up-to-date there, yet!)

Please also remember that an upgrade to a major release should NOT be rushed.
Joomla! core team will support the 3.10 version for 2 more years, so take your time.

Stay tuned for our next Core updates in September!
