What's new in Firebird 2.1.2.18118-0:

April 6th, 2009

· Firebird 2.1.2 is a patch release addressing a large collection of bugs that have surfaced since the original v.2.1 a year ago and the v.2.1.1 sub-release of Summer 2008. This release contains no new functionality but particular attention should be paid to a change in the availability of several parameters in the database parameter buffer (DPB) to ordinary users. It will cause authority errors in applications where, in the past, ordinary users were wrongly given access to operations that must be restricted to SYSDBA and the database owner.

· For Windows users, another important change helps to reduce the hassles involved in making access to the Microsoft C and C++ runtimes available to servers and clients. Documentation of the Windows installation (in the Installation and Migration document) has been updated and reorganised in an attempt to make it better applicable to later versions of Vista, XP and Server2003 with SP3 installed, and Server2008.
