Allgemein

Willkommen bei OpenSimulator 0.9.0.0, einer virtuellen Open-Source-Mehrbenutzer-3D-Umgebung und Metaverse-Serverplattform.

OpenSimulator ist nach wie vor ein hochkomplexes System. Verschiedene Nutzungsszenarien (Standalone, Grid, Hypergrid usw.) in Kombination mit unterschiedlichen Abhängigkeiten (z. B. verschiedene Versionen von Mono auf Linux/Mac) können manchmal zu unerwartetem oder instabilem Verhalten führen.

Wenn Sie von einer früheren Version von OpenSimulator aktualisieren, empfehlen wir Ihnen dringend,' mit den Standardkonfigurationsdateien zu beginnen und alle Änderungen zu portieren, die Sie an Ihrer älteren Version von OpenSimulator vorgenommen haben.

Sie können diese Version des OpenSimulator von http://opensimulator.org/dist herunterladen.

Pivot Release: 0.8.2.1

Aufgrund der Neunummerierung der Datenbankmigration MÜSSEN Sie, wenn Sie von einer Version vor 0.8.2.1 aktualisieren, zuerst auf *0.8.2.1* aktualisieren und dann mit dem Upgrade auf 0.9.0.0 fortfahren.

Upgrade from 0.8.2.1

Install this new version on a clean folder.
Copy OpenSim.ini.example to OpenSim.ini and edit it using your old file only as reference.
Do the same to all ini files on config-include and Regions folders.
You can copy folder assetcache from the 0.8.x version.
If you use SQLite, copy the *.db files also.
Note that floatsamCache is required.

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 is not available, only NONE or CONVEX). 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, but physics shape type may not work correctly. Please fix the meshes uploaded with this option by mistake, either by uploading again with the correct options or fixing the collisions by adding invisible prims, setting the mesh to type NONE, etc. If that is still impossible, then keep using Bullet. But note then we will also change Bullet in future.
ubODE like the older ODE only does single side mesh collisions while Bullet, like SL, does double sided collisions in some cases. Creators doing specialized colliders for physics should take this in consideration. Since in this respect ubODE is the more restricted engine, a collider working on ubODE should also work on Bullet. This version includes some changes also to the external ode library for avatar/mesh collision, but it still displays some instabilities in same corner cases.
ubODE supports CONVEX on normal prims and sculpts. You may have that set by mistake, and my need to fix it.
Using a viewer's physics upload Step2 and Step3 changes the uploaded mesh format. The mesh is simplified and split into a collection of convex parts. This can deform your shape on the viewer side. Uploading without these steps avoids these problems.
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 Editing Undo is currently disabled. It requires a major revision to support large regions.
Adding or removing a large selection of users or groups on Region/Estate lists (allowed residents, banned.., Allowed groups and Estate managers) may display incorrect results. Please reopen Region/Estate, or select one at a time.
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. Mono 4.x series, specially below 4.6 have some issues. Mono 5.x seems to work

Backwards Compatibility Notices

Database

Scripts

If you are not installing on a clean folder, then 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

New experimental InterestManagement features:
- SimpleAngularDistance added to UpdatePrioritizationScheme options. WIth this option objects and avatars information is prioritized taking in consideration distance and approximate apparent size.
- ObjectsCullingByDistance. Setting this to true objects (not avatars for now) outside view range and not sent and/or are delete to/from viewers.
- Current these options only consider the viewer avatar position, not the camera.

Avatars

A few changes in avatar damage. Lost health now depends on relative velocity on collision
Fixed animation sequencing: SitHere, Falling, Stand/Walk etc.

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.

New config variable DisableFacelights to kill those immersion-breaking, silly vanity lights that destroy nighttime RP.

Friends

Option to allow friends to see you on the map should now work.
Object editing 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

Monitoring

NPC

New options available, see NPC section in opensim.ini.example

Objects

Land Impact is now displayed for relative 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
All objects now support CONVEX physics shape type if using ubODE

Permissions

Creation of wearables and animation sets now require creator rights on the referenced items/assets

Physics

BulletSim is the default physics engine with updates to support better vehicle crossings and different default collisions sounds intensity introduced with ubODE.
ODE Now supports variable-sized regions.
New ODE-based physics module: ubODE. This came from the Avination grid and is designed to support more advanced physics features.

Profiles

NPCs can now have a tiny profile

Region/Estates/Parcels

Parcel privacy: viewer option for Avatar on other parcels to see and chat with avatars on this parcel is now supported

Region Cross/Teleport

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.
new bento attachment points added to LSL
Several new LSL and OSSL functions added like: llSetAnimationOverride, llResetAnimationOverride, llGetAnimationOverride, osSetHealRate, osGetHealRate, etc. Please see http://opensimulator.org/wiki/LSL_Status

Services

Sound

Several changes on default collision sounds. Intensity is now related to relative velocity on collision

Stats

Region stats displayed by viewers are by default back to the normalized 55fps on an idle region, independent of region actual configuration. You can see measured times by setting the option Normalized55FPS to false (read OpenSimDefaults.ini). Keep in mind these stats where not designed to profile OpenSim. Do not try to use them for profiling without a much deeper consideration of OpenSim's multitasking nature.

Terrain

Terrain bake is now supported
Terrain edition Undo temporary disabled.

Voice

No significant changes in this release.

Tests

New test dll for checking permission issues OpenSim.Tests.Permissions.dll
