The PHP development team announced that has pushed the release of PHP 5.3 a few more days, now to be released on Tuesday June 30th. Although by the version number it does not *seem* to be a major release, it is. PHP 5.3 packs a good number of new features, some that have been in development for years. Like in any new major release, backwards compatibility is a concern, specially when having new features, reserved words, etc.
