13.04.12.273874

  • This is a maint-server project
  • (Note here: there may be missing the schedule date here)
  • 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)
      • 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.

13.04.05.273580

  • This is a server HTTP improvement project
  • Scheduled 2013-04-16, 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.

13.03.22.272563

  • This is an interest list improvement project
  • Scheduled 2013-04-02, for Second Life Server
  • Features
    • More correct sorting when streaming objects to viewer
    • More objects are categorized as cacheable by the server (improves scene loading speed when revisiting regions)
    • We now recycle packed full ObjectUpdate data for multiple viewers (optimization of how we build UDP packets)
  • Bug Fixes
    • Updates for objects that are out of view are delayed for a maximum of 5 seconds, at which point they will be sent (mitigates BUG-1779)
    • Fix for 'No object updates from vehicles after some region crossings' (BUG-1814)
    • Fix for 'Agent appears in incorrect position to other agents after being moved by a sim teleporter' (BUG-1795)

13.02.08.270166

  • This is the interest list improvement project
  • Scheduled 2013-02-20, for Second Life Server
  • Features
    • Less lag for very crowded regions:
      • Faster sorting of visible objects.
      • Faster construction of ObjectUpdate packets
    • Less bandwidth:
      • Fewer update packets for moving objects that are out of view.
      • Fewer updates for for wind data.
      • No more cloud update packets (affects only 1.23 viewers) for legacy cloud sprite distribution.
    • More correct object updates:
      • Improved sorting of objects near to far.
      • More correct object bounding volumes used for server-side culling.
      • More correct camera position for server-side culling.
      • More correct visibility checks for VERY BIG objects (>32m diameter bounding sphere) that are near limit of viewer draw distance.
    • KillObject messages sent for ALL objects in the region upon deletion, whether the server thinks they are visible on the viewer or not.
    • Less frequent wind variation
  • Bug Fixes
    • Fixed a bug where some regions would fail to send some object update messages to some viewers, in cases where there was a sudden burst of changes and the scene was still in the process of downloading static objects (BUG-655)
    • Fixed a bug that would cause some "out of view" moving objects to stop getting updates thereby causing their motion to be incorrectly extrapolated into the camera's view. There may still some occurrences of the bug, but it has been greatly reduced (PATHBUG-183)
    • Fixed a bug on region crossing that would cause the viewer to cease getting updates from the recently departed region and would cause the region to "disappear" momentarily about 50 seconds after departure (BUG-141)
