Boom - Heal & Support Frames

## Boom 1.4.7

**The big one: the frames were blank inside dungeons and raids.** Every aura
indicator - HoTs, debuffs, dispel, shields, support buffs - went dark the moment
you zoned in, which is exactly where a healer needs them. Fixed. They work now.

### New

- **Class Cooldowns** - a standing row on every frame showing what that player
  brings. The warrior has Rallying Cry and Shield Wall, the shaman has Spirit
  Link. Shown means available, hidden means used. It keeps working in combat,
  where the client stops telling addons anything about defensives.
- **Defensive Cooldowns** - an icon when somebody uses a personal defensive
  (amber) or a group cooldown (cyan).
- **The health bar now takes the debuff's colour** when you can dispel it -
  purple for Curse, green for Poison, blue for Magic, brown for Disease. Far
  easier to catch out of the corner of your eye than a thin border.
- **HoT icons show every healer's**, not only your own. On a spec that casts no
  HoTs the row used to be permanently empty.
- `/boom secrets` - reports exactly which aura data this client is withholding
  from addons, and which tracked spells it will never disclose.

### Fixed

- Joining a group during combat no longer fills the chat with blocked-action
  errors on every pull.
- Nineteen spell IDs across six databases pointed at spells that can never match
  an aura, so those indicators could never have appeared: Prayer of Mending,
  Renewing Mist, Intervene, Prescience, Fortifying Brew, Blur, Tranquility and
  others. All corrected against the live 12.0.7 game data.
- Preservation Evoker's Dream Breath was missing from the HoT database.
- The "missing Prescience" alert flagged every ally, permanently.
- Debuffs whose spell ID the client hides now still colour the bar and show
  their school, instead of vanishing.

### Known limits, stated plainly

Inside a dungeon or raid **in combat**, this game version hides all defensive and
group cooldown data from addons - 0 of 43 defensives and 0 of 26 group cooldowns
are readable, measured live. No addon can show them. The Class Cooldowns row
exists precisely because it does not depend on that data.

Group frames also cannot re-arrange themselves during combat; the game refuses it
for any addon-configured frame. They catch up the moment combat ends.
