Revving to get a new build to pick up the latest LibRangeCheck

This has been tested on Classic with a Rogue up to level 5 using various modules and casually checked against a few level 1 classes. I'm sure there's a lot more to do here. I also made sure to test on Live.

Where possible I tried to check for API availability rather than specific client versions or program IDs. There are many cases where that's impractical, however, so version/program ID checks were used.

This was tested with:
* Ace3 @r1225
* AceGUI-3.0-SharedMediaWidgets @r61
* LibDBIcon-1.0 @v8.2.0
* LibDogTag-3.0 @v80200.1
* LibDogTag-Unit-3.0 @v80200.1-2-g93a898d-alpha
* LibRangeCheck-2.0 @v4.2.3 (with a couple of local changes)
* LibSharedMedia-3.0 @r113-alpha

@@ -1,3 +1,42 @@
+v1.12.0-alpha:
+- WoW Classic compatibility
+
+v1.11.11:
+- Updated TOC to 8.2
+
+v1.11.10:
+- Fixed pet health/power not updating every time it was supposed to.
+
+v1.11.9:
+- Fixed player health never quite reaching full (and therefore never adhering to "full" alpha settings). It seems like a WoW client patch caused UNIT_MAXHEALTH to stop firing.
+
+v1.11.8:
+- Updated TOC to 8.1
+
+v1.11.7:
+- Fixed Warlock shard numeric formatting incorrectly in non-Destruction specs.
+- Possibly fixed reported bug with Brewmaster Monks' Stagger bars.
+- Added several spells to be tracked in the CC modules.
+
+v1.11.6:
+- Only show placeholder icon on custom bars when in configuration mode (fixes placeholder icon showing up for abilities the player hasn't enabled yet, like Survival Hunter's Bombs).
+- Fixed Custom Cooldown bars not displaying properly when both "ignore range" and "only show with target" were checked.
+
+v1.11.5:
+- Added Rogue's Between the Eyes stun to the CC stun bar list.
+- Added option (enabled by default) to hide mod during shell games.
+- Packaged new LibDogTag-Unit to fix hostile NPC class names displaying in all caps.
+
+v1.11.4:
+- Fixed cast lag indicator updating randomly mid-cast.
+
+v1.11.3:
+- Balance druids with Nature's Wrath now treat 50-100 astral power as full for alpha purposes (so the bar will fade to "out of combat" levels when resting around 50%).
+- Fixed the GCD and player castbar lag indicator to show up again.
+- Fixed a longstanding bug where the castbar lag indicator would sometimes be the size of the full bar if the mod never received the client-side "started casting" notification.
+- Improved reliability of castbar lag indicator. Blizzard doesn't offer the necessary events to display this with 100% certainty.
+- Fixed an error caused by the Runes module when toggling "Hide Blizzard Frame" off.
+
 v1.11.2:
 - Fixed Stagger bar to work in 8.0
 - Fixed DK Runes in graphical mode not always correctly showing runes on cooldown (curse ticket 238, thanks ithorazei!)
