Release Notes/Second Life Release/1.21

Category:Release Notes
== Release Notes for Second Life 1.21.6 Oct 16th, 2008 ==
===New features:===
====Support for Mono====
* New option in the Tools menu > Recompile Scripts, to allow your scripts to compile in Mono or the LSL scripting engine.
** Support for Mono has been integrated alongside the original scripting engine, so the use of Mono is completely opt-in. Unless your scripts are explicitly converted to run on Mono, they will continue to run exactly as before. There is no automated conversion to Mono.
** Mono provided immediate performance benefits to scripts. In addition, the integration of the Mono virtual machine will makes future improvements possible.
* Learn more in this video, or read the Mono project page:

====Moderation for Group Text and Group Voice====
* This viewer introduces the ability in group roles to 'Moderate Group Chat', which includes both voice & text conversations in a Group chat session.
** Moderation is only available for formal Groups in Second Life.
*** Moderation is not available for conversations that happen on the fly (i.e. among avatars in Local Chat, nor the spatial voice chat in proximity around you). Moderation is not available for 1-to-1 IMs or 1-to-1 voice calls!
* 'Moderate Group Chat' is an ability that is automatically part of any Owner and Officer roles for newly created Groups. This ability can be changed or added to other roles in any Group.
** The 'Moderate Group Chat' ability can be seen and managed in the existing Group Information window
** Like other abilities, this ability is persisted until formally changed an authorized member of the Group.
:
* IMPORTANT: NOTE FOR EXISTING GROUPS
** For backwards compatibility, all Group Owners (past and present) have been retroactively granted the ability to 'Moderate Group Chat'. This covers all Group Owners.
** In addition, for all new Groups created after 2008-08-19, this ability is automatically given to the default Group Officer role.
** For existing Groups (created before 2008-08-19) the Group Officers do not have this ability granted to them automatically. Officers must manually be given this ability by an authorized member of the Group.
* Using the Moderator Controls:
** A person who has been given the ability to 'Moderate Group Chat' will be labelled as a ...(Moderator) in the Participants List when she or he joins a Group chat session.
** There can be more than 1 moderator in the same session at the same time.
** A moderator does not have the ability to create other moderators during a conversation.
** Only moderators have access to special controls in the UI of the Group session:
*** For every participant in the session, they can choose at any time to:
**** [X] Allow voice chat
**** [X] Allow text chat
*** For Group Calls, the moderator may also set the Voice behavior that affects everyone on the Call + anyone who joins the Call:
**** Voices on by default
**** Voices off by default
* Learn more in the Knowledge Base article about Group Moderation.
====llDetectedTouch features in LSL====
* A new UV-picking feature that allows a prim to report where on its surface/texture it has been clicked.
** This project adds the following new LSL commands:
*** llDetectedTouchUV() - returns the UV coordinates of the point touched.
*** llDetectedTouchST() - returns the surface coordinates of the point touched.
*** llDetectedTouchFace() - returns the face of the point touched.
*** llDetectedTouchPos() - returns the world coordinates of the point touched.
*** llDetectedTouchNormal() - returns the surface normal of the point touched.
*** llDetectedTouchBinormal() - returns the surface bi-normal of the point touched.
*** These commands are valid in the events touch_start(), touch(), and touch_end(). in the case of touch(), where events are triggered as long as the mouse is held down - each event has the current surface point data (allowing grabbing, sliders, levers, and all sorts pseudo GUI builds.)
:
* IMPORTANT: NOTES ON COMPATIBILITY
** Since versions prior to version 1.21 do not support sending coordinates, when a Resident clicks on an object using an earlier viewer (e.g. viewer 1.20), the coordinates will be reported as -1, -1
** Scripters take note! You can build your scripts to detect the value -1,-1 as an "Undefined" touch. The creator of such objects must decide how to handle, message to, or warn avatars who are not running a supported viewer for their content.
===Changes:===
* Changed: VWR-6328: Request for "Tools" menu to not auto-hide anymore
* Changed: VWR-4541: Move the Release Keys button to the World menu
* Added: Support for Friendship offers to include 1 line of freeform text to allow requester to clarify their request
:
* IMPORTANT: NOTES ON COMPATIBILITY
** This feature will be enabled with the next server release to Server 1.25. Once the Second Life Grid is upgraded to server 1.25, any resident who uses viewer 1.21 or higher will be able to receive or send an additional 1-line message with each Friendship offer.
* Added: Allow inventory to be dropped onto IM windows
* Added: Show confirmation for inventory dropped onto IM windows
* Changed: Update the Second Life Installer on Mac to use new, better artwork
* Changed: Change the nameplate on text you type in chat, from "You:" to "{Your Name}:"
* Moved: Move link to the Release Notes is under Help > About Second Life... and point to wiki page of Release Notes
* Removed Feature: Remove the option Advanced > Rendering > Info Displays > Show Depth Buffer
* Removed Feature: VWR-8553: Logitech LCD tab is missing from Preferences
:
* Note: After weighing usage of the Logitech keyboard extended functionality and its cost to maintain and test, Linden Lab has decided to deprecate this feature as of viewer 1.21. Though useful to a small percentage of our residents, it is impractical to maintain as a direct implementation while we continue to develop the Second Life viewer. In the future we are looking to implement better means to support third-party hardware in a more sustainable/plug-in, open source and cross platform manner.
===Changes to LSL:===
* Add an LSL call llGetRegionAgentCount() for count of agents in region
* Add an LSL call llGetAgentLanguage() to get user's viewer language setting
* Add "touch position" information to touch-events in LSL:
** llDetectedTouchUV()
** llDetectedTouchST()
** llDetectedTouchFace()
** llDetectedTouchPos()
** llDetectedTouchNormal()
** llDetectedTouchBinormal()

* Interim Fix: VWR-1789: Dragging multiple inventory items onto someone's profile only silently transfers the last selected
