#189880 by keith.smith based on initial suggestions from O Govinda: much better help texts and descriptions for locale module, actually explaining its extended feature set in Drupal 6.

- Patch #164532 by catch, pwolanin, David Strauss, et al.: improve table indicies for common queries.

#200069 by keith.smith: new standard for 'more information' links in module help texts, as the handbook we referred to before was renamed

#193905 report by greggles, patch by myself: the user account page changed language to the last language set up

#175876 by hazexp, webernet, keith.smith: unify module/theme/translation download links and include more pointers to these locations

#194595 report by hass, patch by myself: native language name is required, so we need to fill it in the updates - also omit it in user listing if the same as the translated language name

#186977 by openwereld: LIMIT on locale module UPDATE query is not needed and is even not PostreSQL compatible, so remove

#184867 by deekayen, catch and keith.smith: fix some spelling errors in our source code and messages printed

 - always prune the whole cache as string additions affect all languages
 - rebuild the language caches as needed, distributing this load among page requests

#169079 by yched: improve consistency of menu API and batch API by allowing batch definition in non .module files, which opens the possibility of better performing batches (which are likely to reside in .admin.inc files generally)
 - apply this change in locale.module
 - improve batch API code documentation

- Patch #150245 by webchick, bjaspan, ralf, Arancaytar et al: move the .schema files into .install files to prevent mistakes.

#171646 by JirkaRybka: store version usage information for every source string, optimize caching and prune the initially unused strings

 - make searches work again, better worded
 - do not cache English stuff
 - fix strike through on string seek page
 - fix exports for translations

#82499 by Jose A Reyero and a little bit from myself: send emails localized in the language needed in specific situations, and centralize mail composing operations with hook_mail()

#141996 by Jose A Reyero and myself: translation block to switch interface languages by default, and even content languages, when a translation module provides the alternate links

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

  Let this be the day where we help revolutionize the online society, and the
  way websites and web services interoperate.  Or something.

Annotate the locale schema to help developers understanding what is stored in some of the far from obvious fields. Patch by myself.

#150521 by myself: streamline locale runtime performance and clean up code by not storing empty translations
