[edit] Release Notes
[edit] General
Welcome to OpenSimulator 0.8.2.0, an open-source multi-user 3D virtual environment and metaverse server platform.
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.
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 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 Download
[edit] Known issues
- Loading scripts from the library section of inventory does not work properly.
- The non-default Warp3D maptile generator currently leaks memory very badly. We recommend that you only use this once at the beginning of each simulator session.
- For other bugs please see the OpenSimulator Mantis bug tracker.
[edit] 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.
[edit] Backwards Compatibility Notices
[edit] Database
- Schema changes in asset store, xasset store, fsasset store, region store, AgentPrefs (new table). Migrations included.
- INVENTORY FOLDERS: in order to make OpenSim conform to what the viewers expect, we changed the numbers used for inventory folders. Here are the right numbers:
- Root folder: 8
- My Suitcase folder: 100
- User-created folder: -1
Although things work as they are, we encourage everyone to consider changing the inventory folders in your DBs, as some of the newer viewers may start to malfunction if they get unexpected folder numbers. This is the migration logic, in pseudo-code:
If folder type == 8 and parent folder != zeroUUID set folder type to -1 If folder type == 9 and parent folder == zeroUUID set folder type to 8 If folder type == 9 and parent folder != zeroUUID set folder type to -1 If folder name == "My Suitcase" set folder type to 100
You should issue corresponding SQL queries in your DB.
- GROUPS: group owner powers were updated sometime within the last 6 months. If you don't see group owners being flagged as owners, you may need to fix the DB:
update os_groups_roles set Powers ='351843720888318' where Powers='349644697632766'
[edit] Scripts
Some scripts may need to be recompiled when upgrading to 0.8.2. If you see script errors on the server console, the best course of action is to delete the script dlls that live under the ScriptEngine folder. Note: do not delete the .state files in those folders; all other file extensions can be deleted.
Alternatively, you can set
DeleteScriptsOnStartup = true
once, then switch it back.
[edit] Changes
[edit] General Robust Server

[edit] Sound
- No significant changes in this release.
[edit] Stats
- By default, OpenSim reports a multiple of the actual physics fps, so that the lag meters in viewers that are designed for other simulators don't report lag when in OpenSim. If you don't care about lag meters, you can now choose to report the actual physics fps (~11fps) by setting a new configuration variable Normalized55FPS=false.
- New metrics reported:
- Logging in Users: number of users attempting to login
- GeoPrims: count of all geometric (prim) objects in the scene
- Mesh: count of all mesh objects in the scene
- XEngine Thread Count: Number of threads in use as reported by XEngine's SmartThreadPool
- Util Thread Count: Number of threads in use as reported by Util's SmartThreadPool
- System Thread Count: Number of threads in use as reported by the Microsoft SDK
- ProcMem: Physical memory in use by the opensim instance in kB. This includes shared (e.g. system libraries) and private data.
[edit] Terrain
- No significant changes in this release.
[edit] Voice
- No significant changes in this release.
[edit] Tests
- New test dll for Robust server and services (Robust.Tests.dll). These tests start a robust server in the background listening in localhost:8002 and test the service connectors, and the services themselves.
[edit] Acknowledgements
