--- RELEASE NOTES ---

Date: 22 September 2006

Execute Query is an operating system independent database utility.

Execute Query Version 3.0final Build 5054
-----------------------------------------

-----------------------------------
Changes for incremental Build 5054:
-----------------------------------
Build 5054 addresses a small number of issues identified with the first 
3.0final downloads. Thanks to all who posted bug reports and suggestions.

1. JDBC Driver entry form panel - added save and name change in drivers tree on 
   name field focus lost.
2. Query Editor - Fixed the parser for multiple query execution where a semi-
   colon at the end of a query after a string char close quote resulted in 
   execution errors (bad tokenisation on parsing).
3. ERD - Modified foreground colour (tables) to allow for selected table colour 
   changes and just apply to all tables unless no selections are made.
4. Connection definiton panel - added save and name change in the tree on name 
   field focus lost in addition to existing methods.
5. Saved drivers and connections tree popup menus - Added new driver and new 
   connection menu items to respective popup menus.
6. Fixed issue when using the Find button on the driver panel which caused a 
   NoClassDefFoundError with certain JDBC drivers (reported on Oracle 10g and 
   selected MySQL drivers).
-----------------------------------

Execute Query has been significantly redesigned for version 3.0beta and includes
a number of new features in addition to extensions and enhancements of all 
previous components and functions.

Central to the redesign has been the underlying layout of the application. The 
MDI interface has been replaced by an easier to use and more responsive tabbed 
panel interface. This has allowed some components that were previously almost
stand-alone internal frames to be more central and controlling features such as
the database schema browser which now functions as a primary and controlling 
component.

New feature highlights summary:

  - Tabbed interface with draggable docked side panels.
  - Multiple database connections.
  - Redesigned query editor allowing more intuitive query execution
    as well as allowing multiple result sets in a new tabbed environment.
  - Wizard style functionality for the more complex tasks.
  - Import/export enhancements including binary object support.
  - Redesigned tools and tool configuration.
  - Draggable/clickable SQL keyword list
  - Improved JDBC driver detection
  - Stored object execution
  - Improved logging and file output
  - Improved table printing
  - Data type comparison across different databases
  - Enhanced SQL script generation
  - ... and many more


Further usability features have been added including more customisation features 
and keyboard shortcuts to often used editor commands including query execution
and the commit and rollback of statements.

The documentation has also been completely rebuilt.

Thanks to those who submitted bugs and suggestions. Keep them coming!
