We have just made public the first EBF to PocketBuilder 2.5.1 which addresses a handful of small bugs and improvements.  This free update is available from:
http://downloads.sybase.com

 Select Support & Downloads, then EBFs/Maintenance, then PocketBuilder...

This EBF is for both the IDE and device side of the product.
The updates include:

• Import Handles PowerBuilder 11.5 DataWindow Syntax
  When importing (or migrating) a PowerBuilder 11.5 target, the DataWindow syntax is properly filtered for the PocketBuilder sensibilities..
• Enhancements for SQL Anywhere 11.0
  Some enhancements to the ODBC driver to account for SQL Anywhere 11.0 and Sybase Central 6.0. However, the default driver is still version 10.0.
• More CABs For Various CPUs
  Customers with different flavors of CPUs on WinCE require the CABs to be marked as supporting them.
  To our traditional ARM (actually 'StrongARM') support we have added ARM720, ARM820, ARM920, and the catch-all 'ANY' marking. The 'ANY' CPU setting requests the PocketPC CAB loader to not perform any CPU matching checks.
  These various CAB files are otherwise exactly the same as the "Bare WinCE" (prefixed with the 'BW') installation CABs.
• Providing CAB INF Files
  To assist those making custom CAB files for their own product installation kits, we are providing the INF files we use to create the PocketBuilder CAB files. These INF files are in the CAB_INF subdirectory under the actual CAB files.
• New System Function - PrintSetupPaper
  We are continually making small changes to help overcome the lack of a printer manager in WindowsMobile. We have added a system function where the application can specify the paper size, orientation, and margins. Whether these values are actually honored are dependent on the actual printer and the driver.

We have also fixed a handful of bugs that have been reported to us.  The interesting ones include:

• CR-539932 - certain syntax errors would crash the PocketBuilder compiler during a full build.
• CR-543644 - UltraLite 10 synchronization would abruptly shut down with a GPF.
• CR-545354 - Setting the 'Autosize Height' property for computed fields gives the "Incorrect Syntax" error.

One thing to note - this is just a ZIP file - simply unzip it.
No "setup.exe" or other installers to mess with...

Note:
This was built on 9-October-2008 (could be read as 10-09-08) and published on Halloween in Beijing - but the time zone difference ended up being 'beggers night' over here.
Oh yes, the build number is 1226 (boxing day) (not to be confused with 'wrestling day').
