Changelog and release notes

This is OpenAlea changelog, which also includes release notes concerning other projects such as Vplants and Alinea.

Release 0.8

Release 0.8.0

The release 0.7.0 was compiled using Python 2.6.2 and a BoostPython version <1.41. There is a major problem with this release that is related to a conflict between new version of Python (2.6.3 and 2.6.4) and old version of BoostPython (<1.41). The version 1.41 of BoostPython solve this conflict and therefore a new release of OpenAlea/VPlants/Alinea is required. Note that OpenAlea itself does not require BoostPython and is therefore fully compatible with any Python version. Only Vplants/Alinea need to be re-compiled

A new branch called release_0.8 was created:

  • openalea: branch created in openalea/branches/release_0_8 at revision 2101
  • vplants: branch created in vplants/vplants/branches/release_0_8 at revision 7524

release status 0.8.0

Release 0.7

Release 0.7.0

Branches have been created:

  • OpenAlea revision 1762 and merge later on (1762:1857). The trunk, r1870 contains all modifications made in the branch.

In addition, we added multisetup.py in openalea.misc (rev1901), which made the official 0.7.0 release of OpenAlea. Source files of this revision are on the GForge.

  • Vplants revision 6722 and merged later on (rev6952). Final revision for the official release if 7012.
  • Alinea 0.7.0 release is 433 (20/21 october 2009).

release status 0.7

Release 0.6

This release includes the components of three projects:

  • OpenAlea - Component framework and visual programming.
  • Alinea - Simulation of ecophysiological and agronomic processes.
  • VPlants - Analysis, modeling and simulation of plant architecture and its development at different scales

This release provides early access to new modules, features and fixes scheduled for release in OpenAlea 1.0.


Please remove your old configuration file (openalea.cfg) before installing OpenAlea (e.g. ~/.openalea/openalea.cfg under Linux, or C:\Documents and Settings\pradal\.openalea\openalea.cfg on Windows).
