Mambots have been renamed as "Plugins" Mambots were introduced in Mambo and offered possibilities to add plugin logic to your site to mainly for the purpose of manipulating content. In Joomla!, Plugins will now have much broader capabilities than Mambots. Plugins are able to extend functionality at the framework layer as well.
The improved installer can be found under the extensions option. With versions prior to 1.5 you needed to select a specific extensions type when you wanted to install it, with Joomla! 1.5 you just select the extension you want to upload, and click on install. The installer will do all the hard work for you.
In Joomla! versions prior to 1.5 there was a distinctive difference on static and normal content. Both content types are still around, but are not handled as separate items. If you want to create static content, just select "uncategorized" as section and category and the content is handled as static content.

This is now defined in the language <lang>.xml file in the language metadata settings. If you are having locale problems (dates don't appear in your language) you might want to check/edit the entries in the locale tag. Note that multiple locale strings can be set and the host will usually accept the first one recognised.
