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

#202425 by keith.smith: standardize reference to block placement page as 'blocks administration page' to avoid any confusion

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

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

- Patch #191073 by Keith: another good string cleanup by Keith.  (Also removed some trailing whitespace.)

#178768 follow up patch by myself: now that we know Drupal module is moved to site_network, we can document is in the changelog

- Patch #144634 by chx: fixed critical bug that prevented language negotiation to work after/when drupal_goto() is called.

Marking code as beta 1 in preparation of the first beta release of Drupal 6, also add back E_NOTICE removal for the release.
