[COMMEND] New Version Of LEAP (2012.048)

A new version of LEAP, the Long-range Energy Alternatives Planning system is now available for download (2012.048).

This new version includes the latest version of the OSeMOSYS mode, with calculations that are now four-times faster and require about 75% less RAM memory compared to the previous version. The new version also fixes a bug affecting the display of charts, a more robust tool for selecting branches & variables in the Expression Builder, and compatibility with the latest version of SEI's WEAP water planning system (3.43).

As always, this version is backwards compatible with earlier versions.

A detailed description of the new features is provided below.

Detailed List of Changes Since version 2012.047==========

* Improved Optimization Calculations using the new compacted version of OSeMOSYS: much faster and much less memory required. Optimization calculations are now four-times faster and require about 75% less RAM memory. For example, in tests calculating the sample optimization exercise over a 60-year period, peak memory use declined from 336 MB to 74 MB, and calculation time declined from 21 seconds to < 5 seconds.

* Improved Expression Builder: Inserting branch/variable references is now much more robust and supports multi-line expressions. Also fixed problems showing WEAP branches and variables in the branch/variable wizard.

* Updated Compatibility with SEI's WEAP water planning system (version 3.43) following significant changes in WEAP's API. If using WEAP in conjunction with LEAP, please update both WEAP and LEAP to the latest versions.

* Fixed problems with charts not drawing correctly introduced in last version (have temporarily reverted back to older chart component).
