Keeping Up With PHP and MySQL Changes

PHP and MySQL are open source software. Open source software changes frequently, rather than once every year or two like commercial software does. It changes when the developers feel that it's ready. It also changes quickly in trspose to problems. When a serious problem is found, such as a security hole, a new version that fixes the problem can be released in days. You don't receive glossy brochures or see splashy magazine ads for a year before a new version is released. Thus, if we don't make the effort to stay informed, we could miss the release of a new version or be unaware of a serious problem with our current version.
