Release Notes

General

Welcome to OpenSimulator 0.9.0.0, 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 version 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.

You can download this release of OpenSimulator from Download

Pivot Release: 0.8.2.1

Due to database migration renumbering, if you are upgrading from a version of OpenSimulator prior to 0.8.2.1, then you MUST first upgrade to *0.8.2.1* and then proceed to upgrade to 0.9.0.0.

Known issues

• Mega Regions are no longer supported. Please save your mega regions in OAR files before upgrading. You will be able to load them either on small regions, or on a large region (var region). See help load oar in this new version. Don't hesitate to ask for help on one of our irc channels since it can be a bit confusing process :(
• Mesh creators can upload a mesh that will only collide with the default convex hull (physics type PRIM not available, only NONE or CONVEX). Since many meshs where uploaded with this option by mistake, for the moment only the new physics engine ubOde will honor this option. ODE and Bullet will keep using a visual LOD with this option, so still show the PRIM type. Please fix the meshs uploaded with this option by mistake, either by uploading again with the correct options or fixing the collisions adding a few prims, etc. If that is still impossible, then keep using Bullet (the default). But note then we will also change Bullet in future. Also note that contrary, to some information currently on blogs this is this a option decided at upload time on a viewer or upload tool. The physics engine in use is irrelevant on the upload process. Avatar meshs are only seem by physics if you rez them in the region.
• The Physics engine ODE (the original one) is maintained for compatibility purposes only. Please avoid creating new content for it. Use it only if your region has a lot of content you can't upgrade now.
• Terrain Edition Undo is currently disabled. It requires a major revision to support large regions.
• For all other outstanding 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

Scripts

Scripts may need to be recompiled when upgrading to 0.9.0.0. 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

run region once, then switch it back to false.

If after this step you still have problems, you may need to delete all contents of ScriptEngine. But note that doing this as last resort makes scripts loose their current state, this can be a problem on some scripts that depend on that state preservation, in particular some commercial products. We do not expect you will need to this on this update, so if uncertain please ask for advice before doing it.

Changes and Fixes

General Robust Server

General Simulator Server

Archives

• The Load Oar command now fully supports the loading of (selectable parts of) a var region into a normal sized region as well as loading (selectable parts of) standard regions anywhere into another standard or var region.
• Parcel data is now dealt with properly and supports rotations just like terrain and objects
• There are some changes to the parameters to Load Oar which are documented here: http://opensimulator.org/wiki/Load_Oar_0.9.0%2B

Avatars

Classifieds

Configuration

• New configuration variable under [EntityTransfer]: LandingPointBehavior. Possible values are LandingPointBehavior_OS and LandingPointBehavior_SL. This option exists to control the behavior of teleporting gods into places that have landing points and telehubs. Historically, there has been a difference: OpenSim (OS) has honored landing points and telehubs even for avatars with god permissions; SL lets gods land wherever they want. Default is LandingPointBehavior_OS.

Friends

• option to allow to see you on map should now work
• Object edition rights sharing should work better.

Groups

Hypergrid

Instant Messaging

Inventory

Map

Mesh/Sculpt

• see above about upload options and land impact
• sculpts have physics type None, Prim and Convex in ubOde. PRIM will collide with full resolution, CONVEX will use a internal generated simplification of that,not necessary a true convex shape

Monitoring

NPC

* new options available, see NPC section in opensim.ini.example

Objects

• Land Impact is now displayed for information purposes only. It is not used to enforce any limits
• Sits on prims without a SitTarget improved if using ubOde
• Objects rez location improved if using ubOde

Physics

• BulletSim is the default physics engine and has minor updates in this release.
• ODE Now supports variable-sized regions
• New ODE-based physics module: ubODE. This one came from avination and seems to support more advanced physics features.

Profiles

Region/Estates/Parcels

• Viewer option for Avatar on other parcels to see and chat with avatars on this parcel is now supported

Region Cross/Teleport

• Region Objects and avatars region Crossing improved
• Scripted vehicle crossings are now supported in both Bullet and ubODE physics engines.
• Teleport landing height changes if using ubOde (and with no telehub or landpoint set) so landing is on top of objects on that location, not inside them. (a side effect is that you may land on roof tops not inside some buildigs)

Scripting

• llCastRay: with ubODE, this function is performed by it with improved performance and more accurate results. according the to physical representation of the objects.
• several new LSL and OSSL functions added like:

llSetAnimationOverride, llResetAnimationOverride, llGetAnimationOverride,

osSetHealRate, osGetHealRate,..

Services

Sound

Stats

Terrain

• Terrain bake is now supported

Voice

• No significant changes in this release.
