Release Notes

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 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.
  • 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.
  • Experimental PGSQL adaptor has bugs when used with built-in groups and built-in user profiles.
  • For other bugs please see the OpenSimulator Mantis bug tracker.

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

Database

  • Schema changes in asset store, xasset store, fsasset store, region store, AgentPrefs (new table). Migrations included.

Changes

General Robust Server

General Simulator Server

Archives

  • No significant changes in this release.

Avatars

  • Fix detach event not being fired until the next time the object is attached. This allows scripts such as AOs to remove animations when detached. The pause added does not affect other avatars or the scene in general and only pauses the avatar performing the detach for an extra 2 milliseconds.

Classifieds

  • Fixed not being charged to create classifieds on money enabled regions

Configuration

Friends

Groups

Hypergrid

Instant Messaging

Inventory

  • Fixed several performance issues regarding initial inventory download by changing the IInventory API. In some cases this has resulted in 10x performance improvement, and much lower CPU spikes during login.

Map

Mesh/Sculpt

Monitoring

  • No significant changes in this release.

NPC

  • No significant changes in this release.

Objects

Physics

  • ODE Now supports variable-sized regions

Profiles

  • Bug fix: Change UserProfiles so that the parcel name is used for a ProfilePick and not the parcel owners name. This change also fixes a bug where if the avatar enters and does not move, creating or editing a ProfilePick would set the parcelId as an empty UUID.

Region/Estates/Parcels

Region Cross/Teleport

Scripting

  • Measure script execution precisely, using a sub-millisecond timer. Needed because some scripts execute very often but for a very short amount of time each time, so previously they showed as using 0 time. Use a 30-seconds rolling window for measuring script execution. Previously it was 30 minutes, and even that didn't work correctly. Ignore time the script spends sleeping. Many LSL/OSSL functions have a sleep-delay at the end. Include XEngine overhead in the timings. Previously it was excluded. See http://opensimulator.org/wiki/Scripts_Performance
  • When the user stops a script, have it remain stopped. Explanation: Previously the script state was never saved for a not-Running script, so upon region restart the script would be Running again. Now they'll remain Stopped even after region restar.

Services

Sound

Stats

  • The simulator now reports the actual physics' frames per second (fps) that is used in OpenSimulator. In normal operation, this number is close to 11. Previously OpenSim reported a multiple of the actual physics fps, so that viewers would get a number similar to that used in Second Life. We no longer do that. We now report the correct physics fps.
  • 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.

Terrain

Voice

  • No significant changes in this release.
