[TYPO3-seminars] seminars 0.9.0 has been released

[Oliver Klee]

Hi all,

I've just released version 0.9.0 of the Seminar Manager extension
(extension key: "seminars").

This is a new major release with lots of new features, cleanup and
performance improvements. Below, you'll find the complete list of changes.

Please make sure to read the upgrade notes in the manual before upgrading.

The most important things:
- You need to upgrade oelib first.
- After doing the DB updates in the EM, you absolutely need to use the
"UPDATE!" drop-down to convert the data into the new formats.
- There were many changes to the HTML templates. So if you are using
customized HTML templates, you most probably will need to modify them.

If you like this release, please submit a rating in the TER. :-)
