MWA Software is pleased to announce that release 2.2.0 of IBX for Lazarus is now available for download from mwasoftware.co.uk/ibx. This is an important update to IBX and all users are recommended to upgrade to the new release. Please read the changelog before upgrade.
The main intent behind the release is to add support for the remaining Firebird 3 features (and some from earlier Firebird releases) that were not supported in release 2.1. This includes:
- Support for SQL Statements INSERT/UPDATE/DELETE…RETURNING. The first two cases are now able to update the current row for all TIBCustomDataset descendents including TIBTable, using data returned following a row insert or update.
- INSERT…RETURNING is used to provide support for Firebird “Identity” columns. For example, when used to provide auto-increment primary keys.
- Firebird “Packages” are now supported by TIBStoredProc and by the SQL Component Editors.
- Additional Firebird 3 properties are now supported by TIBDatabaseInfo and by the Services API components (e.g. TIBConfigService).
- Alternative Security Databases are now supported by the Services API Components.
- TIBExtract now supports DDL Grants and triggers on database objects.
- A new IBServices component to support online validation of a database (TIBOnlineValidationService).
- A major new example application (DBAdmin) is now included. This illustrates the use of IBX for Day-to-Day Database Administration tasks including User Management, Backup/Restore and Database Validation and Repair. It is also intended to provided a useable application that users may use directly or incorporate into their own toolsets. It also demonstrates User Management using Firebird 3 virtual tables and SQL statements. Note: this application also requires the standard Lazarus package MemDSLaz.
This release also incorporates recent bug fixes and includes a 33 page guide to the use of IBX for Firebird DBA activities.

The Firebird Developers Day is an annual Firebird conference that happens in Brazil. So far, it was mainly a Portuguese speakers conference, but this year, when FDD completes its 15th birthday, we are checking the possibility to receive international attendees too. The conference date is August, 18 2018.
The first thing we need to do is to figure out if people outside Brazil has interest to participate in FDD. So, if you live outside Brazil, and would like to come to the 15th Firebird Developers Day, answer this 3 questions survey and let us know!
Firebird Project is happy to announce general availability of Firebird 3.0.3 — the third point release in the Firebird 3.0 series.
This sub-release offers many bug fixes (including fix for a recently reported security vulnerability) and also adds a few minor features and improvements, please refer to the Release Notes for the full list of changes. Binary kits for Windows and Linux on both 32-bit and 64-bit platforms are immediately available for download.
Microsoft, Apple and several Linux distros started to distribute patches to try to fix the recent security flaws found in Intel, AMD and ARM CPUs, in almost every CPU released in the last 20 years. The security flaws are known as Meltdown (affects Intel) and Spectre (affects Intel, AMD and some ARM processors).
The flaw allow softwares to access protected memory areas that should be accessed only by the Operating System kernel, and get sensitive data, like passwords, etc.
There are two problems with the fixes:
- They do not fix 100% of the problem, since it is related on how the CPUs were designed. So far, there is no 100% solution for the problem, and probably it will never exists.
- They impact badly in performance.
In a recent post to firebird-devel list, an user reported that the performance of the Firebird server dropped ~30% after he upgraded its Linux kernel to a version that “fix” those security flaws.
General reports over the internet shows that the most affected areas of the system are CPU, RAM and Disk, so any software that makes intensive use of some of those areas will probably have its performance significantly degraded.
Just to be clear: this performance loss doesn’t affect only Firebird, but any software!
The first pre-beta release of the English version of the Firebird 3 Develoepers Guide is now publicly available. Please report any problems or mistakes. The translation work, from Russian to English, was sponsored by a crowdfunding campaign. Thanks to all who contributed!
The first version (200 pages) of the German translation of Firebird 2.5 Language Reference is ready – you can download it here.
Many thanks to Martin Koeditz, the editor of German version!
Here is an article describing some points to consider, when moving from an older version to Firebird 3. It is a starting point for those who plans to upgrade their installations and wants to save from some headaches.
