11.08.10.238207

11.08.08.237997

11.08.02.237522

  • "maint-server" project. deployed 2011-08-03
    • New Features
      • Enhancements for marketplace item delivery.
    • Bug Fixes
      • Fix for SVC-7104 "Granting/revoking perms broken for non-web-profile viewers"
      • Fix for SVC-7059 "(Spanish) [DATE I18N] Date in English in Group profile > Terreno/Bienes > L$ del grupo > Detalles tab and Ventas tab"

      • Changed logging for TIMEWARP issues.
      • Removed some unused IM code.

11.07.12.235430

  • "Avatar Visibility" project. deployed 2011-07-13
  • Avatar Visibility
    • This new feature adds the ability to control if residents on a parcel are visible to others outside that parcel, as well as the ability to see them. In other words, if TheFirst Resident is on one parcel and TheSecond Resident is on another, while this feature is enabled on either parcel, they will not see each other. Text chat on channel zero is blocked following the same rules.
      • While this feature works with all viewer, a new version is required to change these options. In the version 2.8 viewer, the About Land / Options dialog will have a new checkbox.
    • The llGetParcelDetails() function will now accept a new parameter PARCEL_DETAILS_SEE_AVATARS that may be passed into the function, and it will return an integer flag indicating if the setting is on or off.
    • Both the large map and mini map work as before. Green dots will indicate the approximate location of an avatar, regardless of this new parcel setting.
    • LSL sensors will function normally, and can detect the presence of avatars on parcels with this setting enabled.
    • Text chat on channels other than zero are not blocked by this setting.
    • If an avatar is on a vehicle with this feature enabled, the entire vehicle will not be seen.
    • All existing parcels in Second Life default to the old behavior (showing residents on the parcel). To enable this feature on your parcel, you must have the new viewer with appropriate permissions, and then turn off the checkbox above.
    If the new viewer is used on an older simulator, the option will be checked and disabled.
  • Sound Audibility
    • This feature adds new parcel controls to limit the sounds that may be played by avatars. These are sounds from gestures, played from the viewer inventory, or from scripts on attachments. The parcel owner (or group member with powers to change parcel settings) can set the parcel to allow avatar sounds from everyone, only members of the parcel group, or nobody.
      • A new SecondLife viewer is required to change these settings from their default values. In the version 2.8 viewer, the About Land / Sound dialog box will have a new control:
  • All existing parcels will default to having this set to "Everybody" and thus behave as before this feature was introduced.

11.06.28.234196

  • Josh's "maint-server" project. deployed 2011-06-29
    • Features
      • Added new parameter to llHTTPRequest - HTTP_VERBOSE_THROTTLE. Value is 4, type is integer. If specified in the parameters list as a non-zero value (true), the script will emit errors when the throttle for outgoing requests is hit. If zero (false), the script will remain silent on errors. The default value is true.
        Example: 
        key http_request_id = llHTTPRequest("http://example.com/", [HTTP_VERBOSE_THROTTLE, 0], "");
      • SCR-67: Added new constant PRIM_OMEGA for use with llGetPrimitiveParams, llSetPrimitiveParams, llGetLinkPrimitiveParams, llSetLinkPrimitiveParams, llSetLinkPrimitiveParamsFast. This gives access to the "target omega" property of primitives which can be set via llTargetOmega, but allows getting the current target omega for a prim (previously not supported) and setting the target omega on a child prim (previously only doable with a script on each prim).

The list has the signature [vector axis, float spinrate, float gain] like the parameters for llTargetOmega

Examples: 

// Set this prim rotating
llTargetOmega(<1.0,3.0,0.5>, TWO_PI, 1.0);

// Read back this prim's current target omega
list current_omega = llListToList( llGetPrimitiveParams([PRIM_OMEGA]); // should be [PRIM_OMEGA, axis, spinrate, gain]
vector axis = llList2Vector(current_omega, 1); // Should be <1.0,3.0,0.5>
float spinrate = llList2Float(current_omega, 2); // Should be TWO_PI
float gain = llList2Float(current_omega, 3); // Should be 1.0

// Set all child prims rotating
llSetLinkPrimitiveParamsFast(LINK_ALL_CHILDREN, [PRIM_OMEGA, <1.0,3.0,0.5>, TWO_PI, 1.0]);
    • Bug Fixes
      • Fixed issue with "Buy" option remaining set on purchased child prims of no-mod objects (Originally VWR-9796)
      • Addressed issue with teleport and other service failures affecting simulator hosts.
      • Server-side support for STORM-1261 - send message IDs on login failure to allow localization
      • SVC-6905 : Fixed issue with objects resisting return, delete, take and autoreturn
      • WEB-3096: Fix unsubscribe link in IM-to-Email messages"
      • SVC-6953: Fixed issue where region restart notification appears to be from the avatar being notified.
      • SVC-5780: More specific error message when deeding land to group fails because transfers are blocked on the region
  • merged with server trunk: https://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Server/11#11.06.17.233176

11.06.14.232746

  • The "Group Chat" project. deployed 2011-06-15
  • These are the simulator side fixes for group chat.
  • Enable addressing chat message to more than one agent in a region
    • A protocol was implemented on the sim and in the multiagent chat backbone service to enable addressing of a chat message to multiple agents. When more than one recipient agent is present in the same region a single request is made to the sim addressed to all recipients. Previously a request was made for each agent needlessly duplicating requests.

11.05.05.228940

  • Andrew's "maint-server" project. deployed 2011-05-12
  • Fixed SVC-6951 "Random sim crashes in latest branches"
  • Fixed 2 simulator crashing bugs.
  • Made changes to message logging to be less impactful on simulator performance
  • Removed the physics changes tied to SVC-5880.
    • The fix for this bug was determined to have unintended and adverse reactions.

11.05.03.228703

  • Andrew's "maint-server" project. deployed 2011-05-04
  • Fixed 2 simulator crashing bugs.
  • Made changes to message logging to be less impactful on simulator performance
  • Removed the physics changes tied to SVC-5880.
    • The fix for this bug was determined to have unintended and adverse reactions.

11.04.26.227686

  • Andrew's "maint-server" project, deployed 2011-04-27
  • Bug Fixes
    • SVC-6055 Avatar position reverts to original sittarget in simcrossing
    • SVC-6808 Muting a new-style 'Resident' avatar is ineffective when you're offline
    • SVC-6859 llTeleportAgentHome on an agent not over your land shouldn't result in the target getting the message
    • SVC-6882 Mini-map shows multiple dots for one avatar, but avatar is not ghosted
    • SVC-5880 Vehicles "Jumping" when crossing prims
      • This is caused by the physics engine reporting collision info for "hidden" faces (the vertical faces where the road objects butt up against each other). It has existed since the very beginning of SL and affects all objects (not just vehicles) however it became particularly bad for vehicles after the physics engine upgrade to Havok4 in 2008.04.
      • To repair broken vehicles a "workaround" was introduced to reduce the effect: vehicle collision events get special scrutiny and some collision events are removed. It helps, but is not 100% effective and also has some side effects such as causing vehicles to sometimes partially penetrate curbs, walls, and other obstacles, or even tunnel through walls for small vehicles.
      • To solve this problem correctly in Havok7 a config parameter was tweaked in the physics engine. Also, the aforementioned workaround for vehicles has been removed, so some vehicle behavior may change. Besides a reduction of vehicles penetrating obstacles they may also "jump" more when crossing seams that are not quite lined up right -- short obstacles may cause vehicles to jump where they used to roll smoothly.
    • SVC-6900 Group-owned objects located in private estates cannot send IMs to offline avatars
    • SVC-6403 llGiveInventory is not working!
  • New Feature
  • merged with server trunk + a security fix - https://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Server/11#11.04.22.227477

      This version should changes the way updates for static (non-moving) objects are detected and sent to the viewer. This should be visible as:
      • Faster region load times. It should take less time to see what is around you after a teleport or log in.
      • Faster updates when moving in a region. While flying, for example, objects should appear sooner than before.
