0.7.5 Release

=Release Notes=

General
'''These release notes are in development. The current release candidate for 0.7.5 is RC1'''.

Welcome to OpenSimulator 0.7.5, an open-source multi-user 3D virtual environment server platform.

As ever, OpenSimulator is a highly complex piece of alpha software. It's very likely but not guaranteed to work and various usage scenarios (standalone, grid, hypergrid, etc.) in combination with different dependencies (e.g. different versions of mono on Linux/Mac) can produce unexpected or unstable behaviour. If it breaks you get to keep both pieces.

If you are upgrading from a version prior to 0.7.x, make sure to read the 0.7 Release notes. There have been extensive changes in OpenSimulator from 0.6.x to 0.7.

When you are upgrading, 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

 * There is an occasional issue where other people will see you in the animation-less t-pose when you teleport between regions. This is being handled via http://opensimulator.org/mantis/view.php?id=6483
 * 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. OpenSimulator will run under Mono 3.0.2 but physics instability has been reported (at least with the ODE plugin).

Backwards Compatibility Notices

 * This release includes database migrations but these should be backward compatible with OpenSimulator 0.7.3.1 (i.e. one could rollback to 0.7.3.1 if necessary without also rolling back the database). However, this is not a guarantee - please always backup your data before migrating from earlier OpenSimulator versions.
 * Due to a libomv bug fix, teleports in this release are incompatible with OpenSimulator 0.7.0.2 and earlier. This affects primarily Hypergrid teleports, since simulators within the same grid tend to be all in the same version. Teleports to OpenSimulator 0.7.1 and later should work.

Mesh

 * No significant updates in this release.

Groups

 * No significant updates in this release.

Monitoring

 * No significant updates in this release.
