Release Notes

General

Welcome to OpenSimulator 0.7.4.1, an open-source multi-user 3D virtual environment and metaverse server platform.

This is a security release following on from 0.7.4. As such, it contains a single functional fix.

As ever, OpenSimulator is a highly complex system. 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.

This release is compatible with the existing OpenSimulator 0.8 database without any migrations. There is some additional config in OpenSimDefaults.ini but if you have not changed this file (as is strong recommended) then you do not need to worry about these.

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

• Sometimes creating body parts or clothing fails with no error message. This is not consistent - work around is simply to try again.
• In a stock Linden Lab viewer 2/3, various tabs and buttons will point back to the Linden Lab website. In particular, the profile data will try to fetch from the Linden Lab website. It's not known currently how/whether this can be changed in the stock viewer.
• No form of prim equivalence is implemented for meshes.
• Loading scripts from the simulator library does not work properly.
• Multiple attachments on a single attachment point not supported.
• Bulletsim physics engine support is in an intermediate state in this release and may not work at all under Linux. This will not affect users since the Open Dynamics Engine (ODE) remains the default physics engine in-use on OpenSimulator.

Requirements

OpenSimulator requires:

• .NET Framework 3.5 when running under Windows.
• At least Mono 2.4.3 when running under Mono (Linux or Mac). Mono 2.6.x and Mono 2.10.x onwards work well. Mono 2.8.x versions are reported as less stable in some situations.

Backwards Compatibility Notices

• With respect to OpenSimulator 0.7.4, this release does not contain database migrations. There is some additional config in OpenSimDefaults.ini but if you have not changed this file (as is strong recommended) then you do not need to worry about these. However, as always please backup your database before migrating from any earlier OpenSimulator versions.

Changes

Scripting

• Fix so that llRemoteLoadScriptPin() cannot load scripts into other prims where the pin is unset (equal to 0). Destination prims have an unset pin by default. This bug has been introduced ever since the function was implemented in commit 3697e08 (Fri Jun 27 02:22:33 2008) and so affects all OpenSimultaor versions since before 0.4.

Acknowledgements
