Release Candidate kits of Firebird 2.0.1 are now available for download at the Firebird main site.
This sub-release introduces a number of bug fixes done since the v.2.0 release in November. It does not add any new functionality to the database engine. A minor improvement is detection of Gentoo or FreeBSD during configuration.
An important reversion to 1.5 behaviour has occurred in this sub-release, as follows:
In Firebird 2.0, a deliberate restriction was imposed to prevent anyone from dropping, altering or recreating a PSQL module if it had been used since the database was opened. An attempt to prepare the DDL statement would result in an "Object in Use" exception.
Many people complained that the restriction was unacceptable because they depended on performing these metadata changes "on the fly". The restriction has therefore been removed. However, the reversion in no way implies that performing DDL on active PSQL modules is "safer" in Firebird 2.0.1 than it was in V.1.5.x.
