Hi All,

A new version of LEAP is now available for download (2008.085). Changes in this version include improved memory management (fewer out of meory errors) and better handling of scenario inheritance for complex scenarios constructed as "packages" of mini scenarios.

As always, this version is backwards compatible with earlier versions. You can download the full version from here...

or here:

...or you can use the menu option in LEAP labeled Help: Check for Updates.

Best,

Charlie

Full list of changes since 2008.079===========
(v79 was the last version I announced in this way)

2008.0085: 8/4/2010

* Better Memory Management. On some data sets with large numbers of regions or scenarios LEAP was crashing with an out of memory error. Memory management has been greatly improved which should prevent this from happening.

* Improved Scenario Inheritance: LEAP has for a long time had the ability for scenarios to inherit their expressions from multiple other scenarios. Specifying secondary scenarios allows you to create packages of scenarios that combine mini-scenarios into a single package (e.g. one package for transport policies or one for all efficiency measures). However, until now it was not possible to further combine multiple packages to form an overall scenario (i.e. packages of packages). This has now been fixed. You can use this new feature to combine packages of transport, industry, buildings and supply policies into an overall mitigation scenario.

2008.0083: 6/9/2010

* Improved Allocation of Emissions: Added ability when allocating GHG emissions back to enery demands to list emissions either according to the demand fuel whose consumption drove the emissions or the supply fuel whose combustion actually resulted in the emissions. See Option marked "Alocate emissions to demands" on the General: Basic Paramteres: Scope screen.

2008.0080: 5/3/2010

* Improved Excel(filename, rangename) expression function. Now, in addition to importing values from Excel this function will also import from LEAP expressions entered in Excel. This allows you to store and manipulate your LEAP expressions in Excel.

* LEAP now supports both .xls spreadsheet files and the newer .xlsx file format introduced in Excel 2007.
Improved Copy and Paste. While LEAP has long supported copying ranges of data in Excel and pasting them into LEAP as Interp or Step functions, you can now also copy an Excel cell and then paste it into LEAP as a link to that Excel cell. Use Ctrl-Alt-V or Edit: Paste Link to paste a link to an Excel cell. Note that you can only paste links to spreadsheets that have previously been saved (i.e. not to in-memory spreadsheets).

* Improved the Analysis: Import from Excel menu option. You can now import from a template spreadsheet and use it create links to a set of LEAP expressions stored in the spreadsheet. In this way you can quickly set up a LEAP area in which all expressions are stored and managed in Excel.

* Improved Error Handling. If LEAP detects a corrupted file or fails to open an area, that area will be marked for repair. Next time LEAP is opened, the files in the area will be checked and, where possible, repaired.

* Improved LEAP's Application Programming Interface (API). The API now provides an Area.Backup procedure to backup an area to a named folder.

* Fixed a bug in the Help: Check for Updates feature that was preventing it from working on pre-Windows Vista systems.
Improved Script Security. A new tab has been added to the General: Basic Parameters screen marked "Script Security". Use this tab to control how scripts run on your computer within LEAP. Scripts are files that contain visual basic code that is executed on your computer. Bear in mind that scripts might contain malicious code that can damage your PC. For example, a malicious script could delete files, infect your PC with a virus, or take control of your PC. Hence, you should only allow scripts to run if you received your LEAP area from a trusted source or if you created it yourself. The default setting for scripts is that LEAP will ask you to grant permission the first time a script is to be executed. Thereafter, LEAP will add that script to the list of approved scripts to be run for a given area. For maximum security you can tell LEAP to never run any scripts. You can also tell LEAP to run all scripts without asking. This last setting is the least secure and is not recommended.

* Changed the Help: Register and Help: Register Online menu options so that they are always visible, even if a user has already registered.

* Redesigned Calculations for allocating Transformation energy use and GHG emissions back to demand branches. These calculations are now more realistic under a wider variety of Transformation configurations and are also much faster. Instead of slowing down calculations by a factor of 2 or 3 they now only cause a negligible slowdown. You can include this type of calculation by going to the Scope tab on the General: Basic Parameters screen and checking the box marked "Allocate Primary Energy..."

* Improved Title Captions in Results charts to make them less confusing and added a visible title by default to all Results view charts. The title can be hidden by right clicking on a chart and unchecking "Show Chart Titles".

* Fixed bug in Manage Areas affecting the Restore and Delete features.Fixes

* Various minor bug fixes.
