Firebird V2.0 Final released

Firebird 2.0 is the happy culmination of more than two years' efforts from a broad-ranging, truly international community of dedicated developers and supporters. It brings with it a large collection of long-awaited enhancements that significantly improve performance, security and support for international languages and realize some desirable new SQL language features.

This release contains a large number of new features, including derived tables, support for Execute Block, increased table sizes, new improved index code (the 252-byte index length limit is no longer applicable), expression indices, numerous optimizer improvements, enhanced security features, support for on-line incremental backups along with numerous other improvements and bug fixes.

Features of the release include

  • A thorough reworking of indexing to ramp up performance and minimise bottlenecks in searching and matching
  • Several limitations inherited from the legacy code have now gone, such as the 252-byte limit on index size and the 30 Gb limit on table size.
  • A new interface for plugging in international character sets, including enhanced Unicode support, along with a number of new and corrected collations
  • 64-bit platform support with released binaries available for AMD64 and Intel EM64T on Linux. Windows 64-bit builds are ready for testing and will follow in a sub-release
  • An intense makeover of server security, including beefed-up password encryption and inbuilt protection for brute-force attack
  • Support for SQL200x derived tables, including multi-level nesting and joining of subqueries
  • EXECUTE BLOCK syntax to enable blocks of procedural SQL (PSQL) to be executed in dynamic SQL statements
  • Explicit cursors in PSQL, also available inside EXECUTE BLOCK statements
  • Optional WAIT lock conflict timeout, available as both a SET TRANSACTION argument and as a transaction parameter in the API
  • All-new incremental backup capability
  • Complete re-architecting of "serverless" local connection protocol on Windows to eliminate the inherent instability of the legacy IPServer protocol
  • Fully completed implementation of the Services API on all platforms
