We are happy to release LEPTON 3.0.0 as Release Candidate 1 today.

We have been developing the release 3.0.0 for more than 2 years and some parts have been already released in current or older LEPTON versions, such as setup.ini or LEPTON autoloader, just to enable easier upgrade from LEPTON 2.4.1 to 3.0.0 .

There are massive codechanges in this release in functions and classes but there are also a lot of functions that were removed from the core, for example many functions referring to utf-8 transition, because they are not needed any longer.

Another main development item was the creation of a new responsive Backend Theme, but we didn't want some new colours only...

Therefore the whole code was completely coded from scratch using twig template engine and semantic framework. This enables users to easily create new backend themes using other frameworks like bootstrap.

We hope that users share new BE-Themes.

You can swith the backend theme via backend options from algos to new LEPsem theme. Please keep in mind zthat you now have to login with http://your_domain.tld/backend instead of admins. If you don't like new BE-Theme you can switch back to algos, that will stay standard in LEPTON for some time. 


New releases have to be tested, that is why we released a RC1. Please use the forum to get us informed about bugs, issues and wishes.


Here is a (non-complete) list of changes, see changelog for details:

  • We got new classes in framework, read details in the documentation.

    • "outsorced" and updated responsive filemanager
    • updated tiny_mce
