- Patch #13941 by Promotheus6: Atom feeds have a CONTENT and/or SUMMARY tag instead of a DESCRIPTION tag. Currently, if both tags are present the aggregator appends the content of both fields to replace the content of the DESCRIPTION tag.

- Patch #29275 by Uwe: I'm currently trying to get aggregator.module in shape for being used as a planet-like software for a Planet Drupal. Here's a patch which allows the site admin to specify which HTML tags are stripped from feeds (or not). This is hardcoded in aggregator.module right now, the attached 2-line patch (for HEAD) makes it configurable.

- Patch #29274 by Jeremy: the "fuzzy cache" mechanism is supposed to enforce a minimum time before the cache table is flushed. Logical errors in the fuzzy cache implementation are leading to the cache table being flushed more frequently.  Configuration is simplified by removing all references to "strict" and "loose" caches. Instead, the cache is either "disabled" or "enabled". Additionally, the site administrator can now configure the "minimum cache lifetime", the minimum amount of time cached data will remain cached.

- Patch #29002 by Neil: list_themes() currently returns all themes, not just enabled themes. This functionality is only used in one place- configuration for disabled themes. These configuration pages can be removed with a usability improvement since you shouldn't be able to configure things which are disabled. Additionally, this allows us to remove some extra logic in system_user(). And it it more consistent with the module API which only lists enabled modules.

list_themes() sorts the results by name. This uses filesort in MySQL since there aren't any indexes. Sorting is not used except in system_user(). This one use can be handled with ksort since it is not often executed (only on the user edit screen when multiple themes are enabled).

And a one line fix to remove a variable in system_user() is in here too.

- Patch #29133 by DriesK: forum vid remains when vocabulary is deleted.  Prevents forum topics from getting lost.

  depricated by form API patch though.  Hopefully helps migration.

- Alternative solution for #28721: expand "File attachments"-group on node edit form when files are attached.

   + description field isn't marked as requiered
