13.07.26.279129

• This is the server side appearance project
• Scheduled 2013-08-20 for Second Life Server
• New Features
  • Enabled server side appearance.
    • Added a new capability, UpdateAvatarAppearance, which is used to request a server side bake.
    • An explanation of the new system is available here: Project_Sunshine-Server_Side_Appearance
  • Deprecated and removed the ability of connected viewers to upload baked textures via the UploadBakedTexture capability and via AssetUploadRequest.
    • Client side baked textures are no longer shared with other connected agents, so the functionality was removed.
    • Viewers that do not support server side baking will fail to display avatars correctly.
  • Added IncrementCOFVersion capability, which allows the viewer to request an increment to the cof_version without changing the contents of the current outfit folder.
    • This is intended as a signal to the server side bake system when an item contained by an object in the current outfit folder is modified without any changes to the container.
    • The response to a successful request to the capability includes the current outfit folder version, which could be used for synchronization and verification.
• More details can be found in these previous announcements:

13.06.18.277494

• This is a server maintenance project
• Scheduled 2013-06-25 for Second Life Server
• Bug fixes
  • Neighboring regions should now appear to the viewer sooner after a region restart (SVC-8019)
  • Fixed an issue in which LSL HTTP-in scripts would sometimes see the incorrect URL (BUG-2833)
  • Fixed some crash modes
• New features
  • The simulator now blocks unsupported bits from being requested in llRequestPermissions()
  • New pathfinding character property for llCreateCharacter() and llUpdateCharacter(): CHARACTER_STAY_WITHIN_PARCEL
    • CHARACTER_STAY_WITHIN_PARCEL takes a boolean parameter, either TRUE or FALSE
    • Default setting is FALSE, leading to traditional pathfinding behavior.
      • If a parcel allows scripts and objects and the character does not have the CHARACTER_STAY_WITHIN_PARCEL option enabled, it can freely cross the parcel boundary in both directions.
    • Characters which have CHARACTER_STAY_WITHIN_PARCEL set to TRUE treat the parcel boundaries as one-way obstacles.
      • Pathfinding wander, flee, evade, and pursue behaviors will only choose goal points within their starting parcel.
      • If a character somehow manages to escape its original parcel (e.g. it was 'pushed' out), it will be able to return to the original parcel, but will be unable to leave the original parcel afterwards.
  • New LSL functions for returning objects from parcels
    • integer llReturnObjectsByID(list objects)
      • Requires new runtime permission PERMISSION_RETURN_OBJECTS
      • objects is a list of objects IDs to return to owner
        • Parcel owner, estate owner, and estate managers can not have their objects returned by this method.
        • If the script is owned by an estate owner or manager, this function works for objects located on any parcel in the region.
        • Otherwise, the script can return objects located over land owned by the owner of the script.
      • Throttled at max parcel land impact capacity region-wide per hour.
      • Returns the number of objects that were returned to their owners or an error code.
    • integer llReturnObjectsByOwner(key owner, integer scope)
      • Requires new runtime permission PERMISSION_RETURN_OBJECTS
      • scope is:
        • OBJECT_RETURN_PARCEL to return all objects on the same parcel as the script which are owned by 'owner'. The script must be owned by an estate manager or over a parcel owned by the owner of the script.
        • OBJECT_RETURN_PARCEL_OWNER to return all objects owned by 'owner' which are over parcels owned by the owner of the script.
        • OBJECT_RETURN_REGION to return all objects in the region owned by 'owner' - only works when the script is owned by the estate owner or an estate manager.
      • Parcel owner, estate owner and estate managers can not have their objects returned by this method.
      • Objects which are owned by the group the land is set to will not be returned by this method.
      • Throttled at max parcel land impact region-wide per hour.
      • Returns the number of objects that were returned to their owners or an error code.
    • New error constants for llReturnObjectsByID and llReturnObjectsByOwner:
      • ERR_GENERIC = -1;
      • ERR_PARCEL_PERMISSIONS = -2;
      • ERR_MALFORMED_PARAMS = -3;
      • ERR_RUNTIME_PERMISSIONS = -4;
      • ERR_THROTTLED = -5;

• History

13.04.12.273874

• This is a maint-server project
• Scheduled 2013-04-23, for Second Life Server
• Features
  • CHANGED_REGION and CHANGED_TELEPORT changed() events will now be called on child prims (SVC-3755)
  • New LSL functions for animation overrides: llSetAnimationOverride(), llGetAnimationOverride(), llResetAnimationOverride()
    • Benefits:
      • Reduced scripting overhead:
        • Replacing a default animation is less code run only once.
        • No polling required, no tracking agent state
      • Works seamlessly with existing animations and animation systems
      • Smoother Animation Overrider behavior
        • Current AOs fight the base animation. This lets the user change the base animation for a state so there is no fighting.
    • llSetAnimationOverride(string anim_state, string anim)
      • Set the animation that will play for the given animation state.
      • Animation must be in the contents of the object with the script, or one of the default animations.
      • Requires new runtime permissions PERMISSION_OVERRIDE_ANIMATIONS
    • string llGetAnimationOverride(string anim_state)
      • Get the name of the animation currently set for the given animation state.
      • Requires either new runtime permissions PERMISSION_OVERRIDE_ANIMATIONS or PERMISSION_TRIGGER_ANIMATION
    • llResetAnimationOverride(string anim_state)
      • Resets the animation for the given animation state to the default.
      • Special state of "ALL" will reset all animation overrides to their defaults.
      • Requires new runtime permissions PERMISSION_OVERRIDE_ANIMATIONS
    • PERMISSION_OVERRIDE_ANIMATIONS
      • Only auto-granted for attachments.
    • List of supported animation states
      • "Standing", "Sitting", "Sitting on Ground", "Jumping", "Hovering", "Taking Off", "CrouchWalking", "Walking", "Running", "Hovering Up", "PreJumping", "Hovering Down", "FlyingSlow", "Flying", "Falling Down", "Striding", "Landing", "Soft Landing", "Crouching", "Standing Up", "Turning Left", "Turning Right"
    • Caveats:
      • State "Sit on Ground" will play the default animation in addition to any override set. This is required for correct viewer behavior.
      • Some states are transitional and have undefined behavior if set to continuously looping animations. These states are "PreJumping", "Landing", "Soft Landing" and "Standing Up".
• Bug Fixes
  • Fixed a simulator crash mode
  • Slight region performance improvement when there are no pathfinding characters present
• Changes since 13.04.01.273300
  • If llStopAnimation() is called with the default animation for the agent's current animation state, and the agent has overriden the animation for that state then the override will be stopped (BUG-2164)
    • For example, if a user overrides his sit animation to be "yoga_sit" and then sits on a poseball, if that poseball calls 'llStopAnimation("sit")', then the user's "yoga_sit" animation will be stopped.
• History

13.04.05.273580

• This is a server HTTP improvement project
• Scheduled 2013-04-30, for Second Life Server
• Features
  • More complete and more correct headers on texture and mesh fetches.

    The asset fetch responses, involving texture and mesh fetches, are fairly straight forward. More headers and correct headers will be returned. Viewers will begin to receive the following:

    • Age
    • Cache-Control
    • Content-Encoding
    • Content-Language
    • Content-Length (for meshes)
    • Content-Range (for 206 responses)
    • Content-Type
    • Etag
    • Expires
    • Last-Modified

    The 'Content-Type' for assets will start showing as image/x-j2c and application/vnd.ll.mesh for images and meshes, respectively. Old service behavior will still be present on the grid for a time. And as with HTTP in general, any of these headers may disappear or change in structure or meaning as permitted.

  • Keepalive connections for some HTTP-based services

    The behavioral change for HTTP connections marks the beginning of support for persistent (keepalive) connections. Services transiting the capabilities router, at ports 12043 and 12046, may honor a request for keepalives and keep a connection open after request completion. These services may include such activities as texture and mesh fetching, event delivery to viewer, HTTP-In for LSL scripts, asset uploads and inventory operations. Benefits from keepalives include immediate and future throughput increases and less TCP connection churn (which often disrupts consumer-grade networking equipment).

    The exact set of services that will see this is expected to change over time.
