Minor Enhancements
The 4.623 Beta now incorporates minor enhancements to AUDITOR and QABUTIL.In AUDITOR you can now access a log file of a database while it is being updated. This is enabled by running AUDITOR with the -live command tail.
In QABUTIL the find options that display formulas now display the formulas in a window of four results, rather than one at a time.

Release 4.623
Although release 4.623 is available in Beta, and will continue to be updated from time to time, and is being used as the release upon which future deployments of Chameleon will be based, I do not currently plan to make it the official current DP4 release, which will remain 4.622 for at least the next several months.There is one major item of DP4 development ongoing at the moment - I am working on developing a native OLE DB interface for DP4. This is likely to take several months to complete due to the complexity of the task. It is possible that the final product will also include an updated ODBC implementation, along the lines of the combined OLE DB/ODBC client implemented for Microsoft SQL Server.

Branding Change
As the "Technology Solutions" part of our name is rather a mouthful we have rebranded ourselves simply as Itim. This won't impact DP4, except that the familiar blue diamond icon has undergone a makeover and will now be more of a greenish blue (and will be in 3D into the bargain). Our main web site is now at www.itim.comI will shortly be maing a new 4.623 Beta available with the new branding. This has some quite exciting user interface enhancements. In particular you will be able to incorporate web browser functionality directly into DP4 maps. More details soon...

Revised 4.622 incorporating previous 4.623 Beta files.
Following a number of important recent fixes to 4.622 I have decided to also include the various enhancements originally available only in the 4.623 Beta. As the two downloads were still virtually identical, and there are no compatibility issued, there seemed little point in maintaining two separate new releases, at this stage.A 4.623 Beta will be re-instated later.

Dynaback
The 4.623 Beta contains an updated version of DYNABACK with comfort output during the phase of DYNABACK -COPY which applies the rollback and transaction log. Also additional file buffering is performed in this phase which should improve performance somewhat.Wednesday, June 1st 2005
