This post makes me realize I have done very little to make public the work I have done with IB Objects over the past years.

For everyone’s knowledge, IB Objects has been available on Lazarus for years now and is very mature there. In fact, several bugs and/or deficiencies in Lazarus have been fixed based on the massive amount of manhours that have gone into porting IB Objects to Lazarus. IB Objects has a very large and robust regression testing suite that we had to get Lazarus able to pass, which we accomplished over a year ago. There is a huge commitment between the Lazarus and IB Objects development teams. We have been closely working together for years to make these products work together as optimally as possible.

I suppose some may appreciate being able to more easily port their IBX based applications to Lazarus. However, due to the very poor implementation of transactions in the IBX architecture, among many other deficiencies, I strongly discourage staying with IBX. It has no future with Delphi due to FireDAC native drivers and it’s only hope of continuation is by people who are unfriendly towards Firebird. It’s a great gesture of goodwill to have ported IBX to Lazarus, but it is really only a gesture towards a majority of people staying with InterBase and Delphi.

Also. anyone wishing to have access to IBO on Lazarus may request access to the full sources without cost under the terms of the Trustware License I use.

Note: There are still some visual controls in IBO that aren’t perfected for use in Lazarus. But, all non-visual components are 100% functional.

Kind regards,
Jason Wharton

Firebird Project is happy to announce general availability of Firebird 2.5.3 — the latest minor release in the Firebird 2.5 series.

This sub-release introduces several bug fixes and a few improvements, please refer to the 
Release Notes for the full list of changes. Binary kits for Windows, Linux and Mac OS X on both 32-bit and 64-bit platforms are immediately available for download.

Tony announced new version, IBX for Lazarus 1.1 is now available from

See announcement in the 3rd party Lazarus forum for the change log.
Performance increased with 30-50% in some cases.

Many thanks to Gabor for pointing out the performance issues and for testing updates. This kicked me into cleaning up this part of the code and rationalising the way that IBX handles column names with spaces and special characters in them.

Mark Rotteveel published a snapshot of Jaybird 3.0 for testing purposes.

This is a very early snapshot, a lot of work still needs to be done
before Jaybird 3.0 will be release-ready. We’d appreciate your feedback,
but we’d like to emphasize that this version is unstable and not ready
for production.

The protocol implementation has been fundamentally rewritten and changes
have been made for stricter JDBC conformance. As a result the driver
might exhibit different behavior than previous versions. Read the
release notes carefully to see if those differences are intentional. Bug
reports about undocumented changes in behavior are appreciated.

Current snapshot versions do not support Type 2 and embedded driver

Download from sourceforge

or from Maven from the sonatype snapshot repository

Release notes are online at driver documentation page
