- Patch #204900 by webernet: code style fixes.  Likely my last patch of the year.  Fiew.  Thanks all, and see you on the other side.  :)

#204420 by webernet: do not show messages about status problems to those who will not be able to click and go to the reports

#194369 by lots of contributors: move default files directory to sites/default/files which can be created automatically on install, so no need to bug the user about it, making the install process easier

#197722 by catch, hwsong3i: remove 4.7 to 5.x updates; we only support direct updates from 5.x to 6.x

#196535 by sun, chx, dww: check whether Drupal can issue HTTP requests at all, so we know that this is the cause of problems, not the remote host not responding.

#197690 by JordanCronin (as GHOP 68): server permissions are now explained very well in a handbook page, link to that

#197730 by keith.smith: standardize on a much more user friendly cron reference in help texts, explain its importance with more examples in INSTALL.txt

#199336 by JirkaRybka: remove improper t() use in update code (update goes all in English, but there were some mistakes), and add messages to updates where there was no return value otherwise, so users know what happens in each update

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

#194310 by chx, catch, KarenS: run updates for disabled but previously installed modules, if they are compatible with the current system

#197314 by vitezslav.smid (as GHOP 39): improve/add/update phpdoc in aggregator, comment and system modules

#199883 by KarenS, douggreen: system update 6036 called search_install(), now replaced with actual code to not depend on the ever changing schema

#193604 by hass and dvessel: fix color module to be able to use arbitrary styles, not just style.css, fixing Minnelli coloring and RTL CSS file coloring

#176282 by Desbeers: forum taxonomy was required for non-forum node types, when enabled for forum inclusion

#198461 by chx: use a simple subquery instead of iterating through all nodes and updating the term_node table one-by-one, which easily caused a timeout on sites with lots of term-node associations

#196043 by chx: menu items saved in the update but broken on the new system (due to coming from disabled or old modules) were not possible to delete

#197500 reported by webernet, patch by myself and chx: instead of calling into the Drupal API with _block_rehash(), implement what we need from that right there in system_update_6027

- Patch #163246 by keith smith, freso, O Govinda, catch, webchick et al: fixed minor spelling issues and fixed spacing issues.

#188498 by Rob Loach: user profile category names are stored and compared case insensitively, but the reserved category name check was not case insensitive

#194367 by chx: better targetted user id setting, so auto increment issues will not cause problems with wiped databases

#193510 follow up by webernet: restore updates added through the 4.7.x lifecycle, so any 4.7.x version can be updated to 6.x

#193510 by webernet: remove updates from unsupported Drupal versions, as our policy dictates (and because some API changes make them faulty without further modifications)

#100909 by webernet and RobRoy: improve cron error reporting by defining time tresholds, so if cron stops running after some time, it also becomes an error, but cron not run yet is not an error on installation
