Release Notes

General

THESE ARE DRAFT RELEASE NOTES. THEY DO NOT APPLY TO ANY ACTUAL RELEASE.

Welcome to OpenSimulator 0.8, an open-source multi-user 3D virtual environment and metaverse server platform.

As ever, OpenSimulator is a highly complex piece of software. Various usage scenarios (standalone, grid, hypergrid, etc.) in combination with different dependencies (e.g. different versions of mono on Linux/Mac) can sometimes produce unexpected or unstable behaviour.

If you are upgrading from a previous verson of OpenSimulator, then we strongly recommend that you start off with the default configuration files and port over any changes you made to your older version of OpenSimulator.

As of this release, the default physics engine plugin becomes BulletSim rather than OpenDynamicsEngine. The BulletSim plugin is significantly better than the OpenDynamicsEngine one, both in terms of performance and in turns of support for physical objects and vehicles.

However, physics engines are very complex beasts and the behaviour between BulletSim and OpenDynamicsEngine will be somewhat different. If you want to use OpenDynamicsEngine instead, then please make sure this is selected in the physics paramter of the [Startup] section of your OpenSim.ini.

As this is a wiki page, please feel free to update it with more information about migration or other issues as and when these come to light.

You can download this release of OpenSimulator from http://opensimulator.org/wiki/Download

Known issues

• Arbitrary key:value storage for regions has not yet been implemented for SQLite or MSSQL. This is necessary for temporary attachments settings to be persisted. This functionality is considered experimental.
• Regression in RLV functionality where objects given via the llGiveInventoryFolder() function with a folder name with the format #RLV/~gift are still placed in the #RLV folder but now with the name still as "#RLV/~gift" rather than just "~gift". This is being addressed in http://opensimulator.org/mantis/view.php?id=6311. Any help from viewer developers on this would be much appreciated.
• No form of prim equivalence is implemented for meshes.
• Loading scripts from the library section of inventory does not work properly.

Requirements

OpenSimulator requires:

• .NET Framework 4 when running under Windows.
• At least Mono 2.8 when running under Mono (Linux or Mac). However, we recommend using at least Mono 2.10 as Mono 2.8.x has been reported as less stable in some situations when running OpenSimulator. Mono 3 has also been reported as working well with OpenSimulator.

Backwards Compatibility Notices

• This release includes database migrations but these should be backward compatible with OpenSimulator 0.7.6/0.7.6.1 (i.e. one could rollback to the previous version of OpenSimulator if necessary without also rolling back the database). However, this is not a guarantee - please always backup your data before migrating from earlier OpenSimulator versions.
