Beta-2 Plugins (ex mambots)

Here's a side-by-side of the plugin type selection (filter) in the Manager:

left in red is 1.0: 4 types / Right and below that in blue is 1.5: 8 types, twice as many!

Notice:
the new authentication options,
the XMLRPC addition (now what I'd really like to know is how to use the Blogger API !!!),
the Legacy plugin which allows you to use 1.0.x extensions on 1.5

SEF URLs in Joomla! 1.5 core!

Well, it looks like the dev's heard the people, and gave them what they asked for:
much better URLs as a core functionality!
It's a bit hidden, and you'll need two steps to see the effect:

1. activate SEF in Global Configuration (make sure .htaccess is ok)
2. Go to Plugin Manager => System Request Plugin, and set "Build with real names" to yes as per above.

Then, check out the com_content URLs on your test-site ;)

Thanks guys ;)

The new unified extensions installer

Very nice new extension installer: no matter if you want to install
a component, module, plugin (mambot), template or language,
all you need is this one installer!
Very good styling of error messages too, as showcased here.
And, you have quick links to check on all installed extensions, from
where you can then uninstall any unneeded ones.
