We have updated to Joomla 5.2
We acknowledge and celebrate the hard work by Joomla volunteers, who had the vision to produce a new major version every two years and have delivered, for everyone.
Why tech notes?
We've always written tech notes about our work for our customers. Sometimes we feel like we've forgotten more than others will ever know. So if we think something might be useful for someone else, we tend to write it up. We never identify clients or specifics about our project work here without permission, but the notes here are mostly based on real world experiences.
Hope they help you.

This site serves no purpose unless you are interested in those things. Please read the terms. Especially about it being provided "AS IS, WITHOUT WARRANTY OF ANY KIND"
Joomla
Joomla 5 is FAST! And it has a host of enhancements, while maintaining compatibility with Joomla 4's default theme 'Cassiopeia' which we have customised for this site. Watch the Joomla 5 video, and go to the Joomla 5 landing page to find out more.
- Dark Mode in Administrator: Joomla 5 boasts a more refined dark mode, not just for users but also for administrators.
- Web Assets and Caching: Many improvements to the web asset caching
- Schema.org Integration: Automatic activation of Schema.org data for organisation and site names enhances search engine optimisation.
- Code Optimisation: Speed advancements are noticed due to automatic source code optimisation through the phpcs fixer.
- PHP & Bootstrap Updates: Improved compatibility with PHP 8+ and an update to Bootstrap 5.3.2 ensures that the platform remains contemporary.
- User Interface: Enhancements in dark mode for the Atum administrator template and the new Joomla modal window for select buttons promise a smoother user experience.
- Tools & Plugins: The TinyMCE editor gets an update to 6.7 with added image alignment features. Several scheduled tasks have been moved to scheduler plugins, enhancing system performance.
- Media Management: AVIF support in the media manager and the ability to exclude archived content from smart search indexing improve media handling capabilities.
- Menu sorting: Allowing you to sort the menu in the way you want it.
- Enhanced Security: Events have been migrated to their classes, and the removal of no longer functional Recaptcha plugins boosts security.
- Modern Technologies: Internal code restructuring focuses on utilising more modern APIs. There's added JS Import map support for Web Asset Manager and deprecated fixes for php 8.2.
- Extensions & Compatibility: Joomla 5 introduces Fontawesome 6.4, Codemirror 6, and has updated its Webauthn Library. Notably, Joomla now requires PHP 8.1, MySQL 8.0.13+, MariaDB 10.4+, and PostgreSQL 12+ for optimal performance.
- Cleaner Code Base: Joomla 5 places a strong emphasis on code cleanliness. The transition from older APIs, removal of es5 support, and other heavily coded cleanups ensure the CMS runs efficiently.
Joomla 5 encapsulates modern requirements for a CMS, promising its users a combination of speed, security, and an intuitive user experience.
This site was originally based on Joomla! 4. Look at these screenshots in 640x480 just for old times sake. No changes to the site were required in order to upgrade to Joomla 5.

Site Typography and layout
Bootstrap 5.x
This site is written for Joomla! 5.x. Joomla 5.x uses Bootstrap 5.x, the most popular open source UI framework in the world.
If the text is inside the kbd tag it is an indication that it is a command line for the terminal. If the text is inside the code tag
it is an indication that it is a code term.
Prism
This site also uses Prism, a lightweight, extensible syntax highlighter, built with modern web standards in mind to make code listings easy to see.
Bigger sections of code, like this minimal main.dart source code for the project are wrapped in code tags with a class of language-dart like this:

A few words about copyright
Copyright applies by default to creative work and this is why licenses are needed. This is explained well by the team at GitHub and the whole article is well worth reading.
The Legal Side of Open Source
Everything you've ever wondered about the legal side of open source, and a few things you didn't.
opensource.guide/legal/"Open source is an unusual circumstance, however, because the author expects that others will use, modify, and share the work. But because the legal default is still exclusive copyright, you need a license that explicitly states these permissions. If you don’t apply an open source license, everybody who contributes to your project also becomes an exclusive copyright holder of their work. That means nobody can use, copy, distribute, or modify their contributions – and that “nobody” includes you. Finally, your project may have dependencies with license requirements that you weren’t aware of. Your project’s community, or your employer’s policies, may also require your project to use specific open source licenses."
Licences we use
Licenses become important if you publish your work, because they give permission, state limitations, warranty and liability, and attach conditions. The chief condition here is to display the license in your work.
If you encounter licenses in sample code you use, you should leave them in place. There is a widget for Flutter to display licenses for all the plugins and widgets used in your app which seems like a good idea. In a corporate setting you may need to further review the licenses used in your project with your legal department.
Creative commons
Creative Commons is an international non-profit organisation which has released several copyright licenses, known as Creative Commons licenses, free of charge to the public.
