Shows up to 32 upper-row icons and 16 lower-row debuffs on the default target frame. The existing 5-11-11-5 buff layout and 4-4-8 debuff layout are preserved. With ClassicAPI, harmful auras beyond the first 16 use available upper-row icons.

Installation

Back up your existing TargetFrameBuff folder, then replace it with the TargetFrameBuff folder from the ZIP under Interface/AddOns. Restart the client or reload the UI. ClassicAPI is optional; version 1.17.3 was reviewed for this update. For working reverse sweeps and edges, use ClassicAPI 1.17.1 or newer.

Changes in v0.9.2

ClassicAPI 1.17.10+: use UNIT_AURA_DELTA for applications, removals, stack changes and timing-only refreshes; no periodic aura polling on this path. Rebuild the displayed snapshot to preserve filtered ordering and tooltip index alignment.
Older ClassicAPI retains the 0.5-second fallback below.
Hide native cooldown numbers on our sweeps to prevent duplicate text when countdownForCooldowns is enabled; retain TargetFrameBuff's text controls.
Disable the sweep expiration flash and clear removed/disabled sweeps where supported.
Spellbook and player-pet changes refresh capability-dependent aura presentation.

Earlier changes (v0.9.1)

Refresh auras on target changes and target aura events, with a 0.5-second fallback.
Update only active countdowns every 0.2 seconds using cached expiration; stop countdown work when none remain. Silent timing changes can take up to 0.5 seconds to appear.
Use GetAuraSlots with reusable buffers and UnitAuraBySlot where available; retain the positional UnitAura fallback for older ClassicAPI. Slot IDs never survive a scan.
Display stack counts for upper-row buffs and overflow debuffs, with debuff-type borders.
Gold borders identify enemy buffs ClassicAPI says you or your pet can remove.
Optional reverse cooldown sweeps; countdown and stack text draw above the sweep.
Saved settings, a ClassicAPI AddOn Options panel, and vanilla-compatible slash commands.
Guard against an aura disappearing immediately before its tooltip opens.

Settings

Run /tfb to open AddOn Options when available, or show command help otherwise.

Command	Action
/tfb timers on or off	Toggle countdown text (default on)
/tfb highlight on or off	Toggle removable-buff borders (default on)
/tfb sweeps on or off	Toggle cooldown sweeps (default off)
/tfb size 6-20	Set countdown font size (default 9)
/tfb warning 0-30	Seconds remaining at which text turns red (default 5)
/tfb reset	Restore defaults

Without ClassicAPI the original native aura display remains available without timers, highlighting or sweeps. Settings are retained for use when ClassicAPI is installed.

Timing limitations

ClassicAPI timings are best-effort. Unobserved applications and certain max-stack refreshes can have unknown expiration. Unknown or expired timers hide their text and sweep; the icon stays visible while the aura remains listed by the API. ClassicAPI controls aura ordering and puts your own auras first.

Validation

17 automated scenarios passed using Lua 5.1 with a simulated WoW API; XML parses. This is not a live WoW 1.12/1.18.1 test or an exact Lua 5.0 runtime test. See VALIDATION.md for remaining in-game checks.
