Changelog

v1.0.0

First public release.

• Key bindings. Bind Toggle the window and Pause / resume under Key Bindings → AddonPulse.

• First-run note. A one-time chat line on first install points you at /pulse, the minimap button, and /pulse options.

• Sessions capture comms. Each saved fight/run now records the addon-comms traffic that flowed during it — the Sessions footer shows the total in / out, and hovering the session selector lists the top prefixes by bytes. Captured cheaply from a start/end snapshot, so you can see which addons chattered during a specific pull.

• Event lane on the graph. Combat / pull / death markers now appear as distinct shapes in a lane below the plot — triangle (combat start), square (combat end), diamond (pull), ✕ (death) — instead of overlapping vertical lines. Hover the lane for a time-sorted list of every event, so a cluster of markers around the same moment is finally readable. Works on both the live Addons graph and saved sessions.

• Polish & fixes. Lower idle cost (the loaded-addon flag is event-driven instead of polled every tick); smoother window resize (the table re-layout is coalesced during a drag); the live graph no longer shows a false spike tick the first time you reopen the window; memory churn is measured against real elapsed time; resumed dungeon runs record their spike counts; and Reset graph now clears the spike history too.

• Sessions now record context. Each saved fight is tagged with its difficulty (N / H / M / LFR) and Kill / Wipe result; dungeon runs get their Mythic+ key level (and affixes). Shown in the session dropdown and footer, so "Boss X" becomes "Boss X — M · Kill" and a run becomes "+18".

• FPS overlay on every graph. Sessions record the frame rate over time (avg / min in the footer), and the live Addons graph keeps a rolling FPS history too — both overlay a faint green FPS line, and the hover readout reports the FPS at that point, so you can line an addon's CPU spike up with the actual frame-rate dip.

• Per-character sessions & baseline. Recorded fights/runs, the in-progress run, and the memory baseline are now saved per character (via SavedVariablesPerCharacter) instead of account-wide — your alts load different addons, so their captures and baselines shouldn't mix. Settings (columns, layout, rates, bar) stay shared account-wide. Existing data is migrated to the character you're on at first login.

• Comms tab gained graphs and depth. Each prefix now has a traffic graph (bytes/sec over time) and a per-row sparkline, Rate and Peak columns (sortable — burst-happy addons rise to the top), a channel breakdown in the tooltip (Party / Raid / Guild / Whisper / Instance), and average message size + message rate. Lets you actually see when an addon floods the network (e.g. a sync storm on joining a group) instead of just a running total.

• Appears in the game's options. AddonPulse now registers under Game Menu → Options → AddOns, with a panel that summarises the addon and opens the full options window / the main window, plus the slash reference — so it's discoverable where people look for settings first.

• Column header help. Hovering any column header now shows a short bubble explaining what it measures (and a reminder it's click-to-sort).

• Memory graph zooms to fit. Memory is usually large and changes only a little, so a 0-based axis showed it as a flat line near the top. The memory graph now scales to its own min–max so growth / churn is visible; when memory genuinely didn't move (e.g. a fight recorded with the window closed, where per-addon memory isn't sampled), it labels the line steady instead of looking broken.

• Minimised bar shrinks to fit. When you minimise, the bar now narrows to a compact ~600px (its stats + title), instead of staying as wide as the full table — so the collapsed monitor takes far less screen. It restores to the full width when you expand.

• Reset CPU renamed to Reset graph. The old name overpromised — it can't clear the Peak / Sess / Enc columns (those come from the game's native profiler and only a /reload zeroes them). It now honestly clears the live CPU + memory sparkline / graph history, with a tooltip spelling that out.

• Memory scan pauses in combat. The per-addon memory walk (UpdateAddOnMemoryUsage) is a single blocking call that can't be made async (WoW's Lua is single-threaded), so it's now kept out of combat by default — the unavoidable hitch lands where it's harmless instead of mid-pull. Per-addon memory holds during a fight and refreshes when it ends. Re-enable with Options → Profiling → Scan memory in combat.

• Memory baseline / diff (ΔMem). The Tools button on the Addons tab snapshots every addon's current memory; the dMem column (added automatically, also in the Columns picker) then shows each addon's growth since that moment — green when it shrank, warming as it grows. The leak/regression hunter's tool: set a baseline, raid for an hour, see exactly what ballooned. The snapshot is tiny and survives reloads.

• Pin & ignore addons. Right-click any Addons row to pin it to the top (teal edge marker) or ignore it (hidden from the list). Tools → Show ignored reveals ignored rows dimmed so you can right-click to un-ignore. Your pin/ignore lists persist and aren't touched by Reset to Defaults.

• CPU as % of frame budget. Options → Display → Show CPU as % of frame switches every CPU figure from milliseconds to a percentage of one frame's budget (set by target FPS, default 60 → 16.7 ms = 100%). "12%" reads faster than "2.0 ms" when you're judging frame impact.

• Window scale & opacity. Options → Appearance — size the window from 70-130% and set its background opacity. Applied live.

• Options window. A panel for tuning everything that has a default — sample interval, memory-scan interval, live history, the session caps, auto-delete age, and the two profiler toggles (memory profiler, spike-timing capture) — each with a Reset to Defaults button. Open it from the title-bar cog menu (Options...) or /pulse options. Changes apply live.

• Spike-timing capture is now optional. The per-fight spike timing (the extra >50ms reads each tick while recording) can be turned off in the options (Capture spike timing); the per-fight spike counts still come for free from start/end snapshots. Lets you trim recording cost to the bone.

• Memory-profiler toggle (Mem prof). Unchecking it skips the per-addon memory scan (UpdateAddOnMemoryUsage) entirely — that scan is the one heavy, spike-prone thing AddonPulse does, so CPU-only mode is much lighter (no per-addon memory columns, but no memory spikes either). The title-bar Memory readout still works (it's the cheap total-UI figure).

• Spike annotations on the graph. Red ticks along the top of a live addon's graph mark each interval it had a frame over 50 ms — so you can see when it stuttered, which the averaged CPU line hides.

• Sessions capture spike counts + timing. Each saved fight/run records how many frames each addon went over 10 / 50 / 100 ms during that fight (row tooltip), and now also when the >50ms spikes happened — so the saved session graph gets the same red spike ticks as the live one. The timing is stored sparsely (only the intervals that spiked), so it adds only ~10–25 KB across all sessions.

• Sessions auto-rotate by age. Saved sessions older than sessionMaxDays (default 14) are dropped automatically (on save and at login), on top of the existing count cap — so the saved file can't grow without bound.

• Selectable Addons columns. A Columns button on the Addons tab picks which columns the table shows, from: Mem, Churn (mem/s), Recent, Peak, Session, Encounter, Last, and the spike counts >10ms / >50ms / >100ms / >500ms / >1s (cumulative frames over each threshold, straight from C_AddOnProfiler). Each is sortable. The sampler only reads the metrics for the columns you've enabled, so showing more costs a little more and showing fewer costs less. The window widens automatically to fit the columns you enable (and won't shrink below that), so the table can't overflow onto the addon names; the per-row sparkline also steps aside when space is tight. Remove columns to let it shrink again.

• Compatible with patch 12.0.7 and 12.1 (## Interface: 120007, 120100), so it loads without the "out of date" flag on either. None of the APIs it uses changed in 12.1.

• Title-bar stats + cogwheel. A gear button in the title bar picks which brief readouts show on the bar — FPS, CPU, Memory, Comms. They stay live even while minimised, so the collapsed bar is a compact at-a-glance monitor. Your selection is saved.

• Putting Memory on the bar is the only one that costs anything (it triggers the per-addon memory walk, on the same slow ~10 s cadence, and only while the bar is visible); FPS / CPU / Comms are free.

• The cog sits to the left of the minimize button, and the bar stats are right-aligned (the AddonPulse title stays on the left).

• Added Home and World latency to the bar options (off by default). They're free — GetNetStats() just reads the client's cached latency values.

• Sessions picker is now a searchable dropdown instead of < > arrows. It lists every saved fight/run with its name, duration and how long ago it was, and you can type to filter by name.

• Every session row now has a sparkline/graph. Previously the per-tick timeline was kept only for the few top CPU users, so only those rows had graphs; now every addon kept in a session (notable on CPU or ≥3 MB, up to 40) keeps its timeline. Applies to newly captured sessions.

• Fixed the minimap tooltip not updating its Active/Paused line on right-click (it rebuilds in place now instead of needing a re-hover).

• Enable / disable is now obvious: every toggle (button, minimap, or slash) prints to chat and shows a brief on-screen note, and the minimap tooltip's Active/Paused line updates live on right-click instead of needing a re-hover.

• The bar keeps working while paused. Pausing only drops new per-addon sampling and recording — the title-bar FPS / CPU / Memory / Comms readouts stay live, so you can run AddonPulse as a lightweight stats bar with the heavy profiling off. (Those readouts are all cheap: FPS and comms are free, the native CPU profiler is always on, and bar Memory is total UI memory rather than the per-addon walk.)

• Everything already captured stays viewable while paused — saved sessions, comms, the existing graphs, and the last Addons snapshot all still open; the footer shows paused so it's clear the per-addon numbers are frozen. (Pause stops collecting, not viewing.)

• Removed the separate Background checkbox (and /pulse bg). The Active / Paused toggle is now the single on/off for all background work: enabled = sample + record everywhere (closed/minimised included); paused = bar stats only. One control instead of two overlapping ones.

v0.9.0

• Master enable / disable. A new Active / Paused toggle pauses AddonPulse's per-addon sampling and auto-recording — for when you don't need the detailed profiling running. Toggle it three ways: the Active / Paused button in the toolbar, right-click the minimap button, or /pulse on · /pulse off · /pulse toggle. The state is saved.
  • Note: this pauses AddonPulse's own work. Blizzard's native CPU profiler can't be turned off (it's built into the client and costs ~nothing). Closing the window also parks most of the work, but combat/instances still auto-record unless you pause.
• Repurposed the old CPU-profiling button — obsolete since CPU is now native and always on — into the Active/Paused toggle. /pulse cpu now just says so on modern clients.

v0.8.0

• AddonPulse no longer shows up as its own CPU spike. Per-addon memory needs UpdateAddOnMemoryUsage(), which walks every addon and is expensive; sampling it every 2 s made our own ticks register as a periodic >10 ms spike. Memory is now refreshed on a slow cadence (memSeconds, default 10 s) and only while the window is on screen — there's no memory walk at all while closed or minimised, even mid-fight. It refreshes immediately when you open the window.
• Trimmed the per-tick CPU reads to what the table shows (recent / peak / session / encounter + the spike flag); the tooltip and graph read last / over50 / over100 live for just the one addon they display.
• Reminder: the >10/50/100 ms spike counts are cumulative since login, so they only grow — a /reload zeroes them.

v0.7.0

• Graph annotations.
  • Event markers — coloured vertical lines mark combat start/end, boss pulls (encounters), and deaths on the timeline, so you can line a CPU/memory spike up with what was happening. They're recorded live and stored with each saved fight/run, so they persist.
  • Hover readout — mouse over the plot for a crosshair plus the exact value and time at that point, and the name of the nearest event. The hover only does work while the cursor is actually over the graph.
  • Marker toggle — a dedicated strip below the graph cycles markers all → pulls + deaths → off (to cut the clutter on long runs) and shows the graph's time window (e.g. Last 3m00s).
• Fixed a Comms-tab error when another addon sends a non-string addon message payload (e.g. ElvUI's numeric version broadcast) — byte counting no longer assumes the payload is a string.

v0.6.0

• Lower footprint. The sampler is now a C_Timer ticker instead of a per-frame OnUpdate, so there's no per-frame work at all. While the window is closed or minimised, only recent CPU + memory are read per addon (the other profiler metrics and the leak scan are skipped) — so background recording is much cheaper.
• Active runs survive reloads. An in-progress dungeon/raid run is now saved once at logout (not every frame) and resumes when you re-enter the instance, so reloading mid-key no longer restarts the run.
• Sparkline follows the Graph toggle. Each row's sparkline now plots CPU or Memory to match the Graph: CPU / Mem button, and matches its colour.
• Minimap tooltip drops the redundant "drag to move" hint.

v0.5.0

• Sessions persist across reloads. Captured fights are now saved to disk, so the reload after a raid or M+ no longer wipes them — open the window any time afterwards to review. Saved snapshots keep the full timeline only for the addons that actually used CPU, so the saved-variables file stays small.
• Whole dungeon / raid tracking. Entering a dungeon or raid starts a run that records across the entire instance (trash and bosses), finishing when you leave. So you get both the per-pull fights and the whole-run picture.
• "Last Fight" tab is now "Sessions", with a < name (kind, duration) > picker to browse every saved fight and run, newest first. Each shows its per-addon CPU peak / average and memory peak; click a row to graph the timeline. Clear removes the shown session.
• Keeps the last 8 fights and 4 runs by default.
• Note: an in-progress run is still in memory, so reloading mid-instance restarts the run (completed fights are already saved). Sessions persist once finished.

v0.4.0

• Background recording. Sampling no longer stops when the window is closed or minimised — an always-on driver keeps the history filling, so you can close the window during a fight and open it afterwards to see what happened. Toggle with the Background checkbox or /pulse bg (on by default). Even with it off, recording still runs while you're in combat so fights are never missed.
• Last Fight tab. Every combat segment is captured into a frozen snapshot — named after the boss when there's an encounter — covering the whole fight regardless of length. The tab lists each addon's CPU peak / average and memory peak for that fight; click a row to graph its full timeline. Clears with the Clear fight button. Stored in memory (not across reloads).
• The footer shows recording fight / in encounter while combat is live.
• Fixes the previous behaviour where minimising the window threw away history.

v0.3.0

• Removed the Events tab — the per-event view wasn't pulling its weight.
• All CPU metrics are now columns, not a cycle button: the Addons table shows Recent / Peak / Session / Encounter side by side, each sortable.
• Wider CPU sparkline with a faint chart background, so it's easier to read.
• Fixed the status flags. The leak/spike markers were Unicode glyphs the default font doesn't have, so they showed as empty boxes. They're now solid colour dots: orange = possible memory leak (steady climb), red = CPU spike (has used over 10 ms in a frame). Both are explained in the tooltip.
• Sort arrows and other indicators switched to font-safe textures so nothing renders as a missing-glyph box.
• The window is a little wider by default to fit the extra columns; the minimap button is now plain left-click to toggle (it no longer touches profiling).

v0.2.0

• Native profiler. CPU now comes from Blizzard's C_AddOnProfiler, which is always on — no scriptProfile, no reload. CPU is reported as milliseconds per frame, and each addon carries native recent / peak / session / encounter averages plus counts of how many frames it blew past 10/50/100 ms.
• CPU metric selector. The CPU: … button cycles the CPU column (and the sort) between Recent, Peak, Session, and Encounter — so you can rank addons by their worst spike or by their cost during the current boss fight.
• Tabs. The window now has three tabs sharing one table:
  • Addons — the per-addon view, now with a CPU sparkline per row, a leak flag (▲, sustained memory climb) and a spike flag (◆, has gone over 10 ms/frame), and a richer tooltip + detail graph (peak/session/ encounter, spike counts, memory peak/avg/churn).
  • Events — global per-event CPU and call count (GetEventCPUUsage), e.g. how many times UNIT_AURA fired and what it cost. Needs script profiling; the CPU button prompts the reload.
  • Comms — per-prefix addon-message traffic, bytes + messages in/out, captured from SendAddonMessage / CHAT_MSG_ADDON.
• Encounter awareness. The footer flags when you're in a boss encounter, and the Encounter CPU metric reflects per-fight cost.
• Memory churn (KB/s) and a coarse leak heuristic are surfaced in the tooltip and the detail panel.

v0.1.0

• First release. A live per-addon resource monitor.
  • Table: every installed addon with its current memory footprint and, when script profiling is on, its CPU/s (milliseconds of CPU time per real second). Values are colour-coded green → yellow → orange → red by severity, with an inline bar showing each addon's share of the sorted metric.
  • Sorting: click the Addon, Memory, or CPU/s header to sort; click again to flip the direction.
  • Filter: type in the search box to narrow the list by name; toggle Loaded only (hide installed-but-unloaded addons) and Hide idle (hide addons using almost nothing).
  • Graph: click any row to pin it to the history graph at the bottom. Switch the graphed series between CPU and Memory, or hide the graph entirely. History covers the last ~3 minutes.
  • Minimise: the – button collapses the window to its title bar; + restores it.
  • CPU profiling: CPU metering needs the scriptProfile CVar, which only takes effect after a reload. The CPU button (or /pulse cpu) flips it and offers to reload. Reset CPU zeroes the counters for a fresh baseline.
• The window is movable (drag the title bar) and resizable (bottom-right grip); position, size, sort, filters and the pinned addon are all remembered.
• Nothing is sampled while the window is closed or minimised, so idle cost is zero.
• Slash commands: /pulse, /addonpulse, /ap — toggle the window; /pulse cpu toggle profiling; /pulse reset reset CPU counters; /pulse status print the profiling state.
• Optional minimap button (left-click toggles the window, right-click toggles profiling) when the LibDBIcon library is present.
