Release notes

Every change to Indicators in the om CLI's changelog, newest first, one section per release: the runtime and its four contracts, the sheet, the scaffold and templates, the chart lanes that draw Indicators, and the commands that install, preview, and publish them. Entries that touch other parts of the product stay in the full CHANGELOG.md. Where an entry names the old language, kScript (legacy), it is the parity program that proved Indicator ports of registry kScript indicators bit-exact; those ports are the rows that carry a New engine badge on the chart. The kit's scaffold, runtime, and marketplace commands predate the changelog's coverage, which begins at v0.4.0.

A release that is missing from this list changed nothing an Indicator author can observe. To see what a release means for an installed machine, Releases overview has the upgrade checklist:

om upgrade
om wrun build ./my-indicator

v0.398.1 (2026-09-22)

Added

• A label handle has an align word. left, center or right (absent is center): the text edge that sits on the handle's x, with (x, y) staying the point. A sheet declares the default with handles.label({ align }); a code-first workspace gets the ALIGN_* constants and .align(...) on a live label (scaffold version 14), and the chart's drawings widget label item takes the same word.
• The hud-terminal template. A code-first template that draws a terminal-style HUD from inside the package: a title bar and a body box anchored top-left, four left-aligned label rows (last close, bar change, a 20-bar signed flow figure from side-split trade volume, a status line) rewritten only on the live bar, and a data-only flow output (HUD terminal).

v0.392.5 (2026-09-21)

Added

• Live tape as a celled source class. A tape input reads the daemon's live trade stream as [offsetMs, price, size, side] cells per primary bar, at or above a required min_size in the trade's native amount; history other than "0" refuses by name (wrun_tape_history_unavailable), because the data plane has no raw trade lane. One rolling buffer per market (two hours or 200k prints, trade ids deduplicated) opens on first use and closes once the market goes idle; the alert tick, the indicator preview and in-daemon rule reads pass it to the compute, and a lane without one (a backtest replay, a one-shot CLI read) refuses wrun_tape_unavailable. Scaffold version 13 declares tape.cells and the min_size / history input facets (Data sources).

v0.392.0 (2026-09-21)

Added

• Anchors on drawing handles. A line, box, label or polyline handle may name an anchor: nine pane spots (top_left through bottom_right) or the four edges, in CSS pixels from the pane's content rectangle, so a HUD keeps its place while the chart pans. The kind declaration may carry a default (handles.label({ anchor: "top_left" })), .anchor(ANCHOR_*) sets it per handle and ANCHOR_CHART restores chart coordinates (scaffold version 12). The chart's drawings widget kind takes up to 256 anchored items (Drawing objects).

v0.391.0 (2026-09-21)

Added

• The fourth contract: frames. abi_version: "wrun-4" adds one import to the third contract, a frame channel: frame(name) declares up to 8 snapshot slots of at most 96 KiB each, writeFrame(...) in finalize() replaces the run's snapshot, and the sheet binds a frame to a docked level profile (plot.levels, up to 512 monotonic prices), a panel below or beside the chart (panel.bars, line, scatter, histogram, pie, heatmap, table, tiles) or a widget (draw.ladder, draw.feed, draw.meter). A series input (sheet only) reads a watch value or an installed series snapshot on your machine. The first three contracts stay frozen (Drawing primitives).

v0.390.0 (2026-09-20)

Added

• Packages can declare a card. draw.card(...) in the sheet's drawings binds rows to outputs (with a format), string slots or literals, a state from an output, a colour ladder and a countdown; the chart draws it from the newest complete row (Drawing primitives).

v0.366.0 (2026-09-18)

Fixed

• A broken local package stops shouting on every command. A package that failed validation logged its whole ABI reason to the terminal on every om packages, om packages show, chat turn or MCP call. The reason now goes to runner.log, the package row reads failed validation · om wrun list says why · om wrun remove <id>, and om indicator list names the remove verb beside each skipped package.

v0.348.0 (2026-09-17)

Fixed

• A live condition source reads a package operand on the bar it declared. A source declared eval: closed decides on closed bars only, and its built-in operands did; a wrun/ operand was computed with no closed-bar cut, so the live tick folded a value that included the bar still forming, and a crossing on it could fire a bar before the backtest replay did. The live projection now takes the same cut, and a source whose primary operand is a package folds once per closed bar.

v0.343.0 (2026-09-16)

Fixed

• Edge comparisons on package outputs carry their bar identity in condition sources. An Indicator inside a crosses_above / crosses_below comparison arrived with no bar identity in the source lane, so the same-bar guard withheld the cross on every bar and the run reported a flat book as warm-up. The identities are threaded on the source replay path too, and the fold reads each operand by that operand's own bar.

v0.337.0 (2026-09-15)

Changed

• One source tree for these docs. The website shape is built from docs/indicators into ignored output with one full-text bundle (llms-full.txt); the published pages are unchanged.

v0.290.0 (2026-09-13)

Changed

• The registry contract is one installed package. The schema modules the registry used to copy from the SDK (the package spec, the metric id grammar, the watch condition and the wire shapes) live in @openmarket/contracts, and om publish reads the registry's contract version once per attempt, refusing on a major mismatch with one sentence naming which side to upgrade.

Fixed

• om open @scope/name on a kScript (legacy) package reads the resolve's real fields. A package whose every version is discontinued says so and points at package_show for the author's note, and the chart title is the package's display name.

v0.244.0 (2026-09-08)

Changed

• A strategy holds on a side that has gone quiet. A strategy's rule reads an operand as not ready when its newest bar is older than one bar of that operand's own grid (a package's primary interval, otherwise the selector's), the way it reads an operand still warming up: a rule the fold can settle without that operand still acts, with the quiet side named in the strategy's health note.

v0.242.0 (2026-09-08)

Added

• Composable packages. A set of watches publishes as ONE package and installs as ONE watch (om watch share --group <label>, or --ref <slug> repeated with --name, the same flags on om publish); the pack carries each source, each step and the exact dependency pins, so an Indicator a condition reads installs first as an ordinary install of its own name. The example examples/packages/btc-sma-desk is a three-source composite with an Indicator-backed condition.

v0.238.0 (2026-09-07)

Changed

• The default registry is staging until launch. The CLI's default registry origin is https://registry-staging.openmarket.xyz; OM_REGISTRY_URL keeps overriding, and follows or shares minted against either OpenMarket registry keep resolving. Priced listings landed in the same cut: a manifest pricing tag is validated at publish and install, and om install on a priced listing you have not bought refuses with the price and om buy @scope/name.

v0.234.0 (2026-09-06)

Added

• The third contract: feature parity with kScript (legacy). abi_version: "wrun-3" adds a handle-keyed draw channel through which finalize() creates, mutates and deletes lines, boxes, labels and polylines across bars (500 live per kind, 1,500 in all, 256 points per polyline, 4,096 draw calls per row) and a last-bar flag (bar.isLast()) with a close-confirm rule that keeps a live session bit-identical to a full run; the sheet gains a handles map, a label renderer position and a text renderer style. The strategy channel rides the same contract: strategy(...) in the file, strategy.long(...) / short / exit / close builders in finalize(), the engine's own broker run by the host, the reserved strategy.position and strategy.equity outputs, and om backtest replaying the trade list from the same bars, params and sheet. The TA library grew from seven classes to the whole kScript catalog, 52 stateful classes in src/sdk/ta.ts (scaffold version 9). The first two contracts stay frozen (Drawing objects, Strategies overview, TA library).

v0.224.0 (2026-09-05)

Removed

• The signal noun and its verbs. One watch primitive replaced the alert, signal, strategy, schedule and stream nouns, their CLI verbs and their tools; an Indicator's consumers are watch conditions, screens, series and backtests. The hosted kScript (legacy) alerts bridge went with them: an alert on an Indicator is a watch on your machine (Alerts).

v0.221.0 (2026-09-04)

Added

• One ledger of what is installed. om packages lists every install as one row: the copy on disk, what it made here (the alerts an Indicator's metrics feed, watches, schedules, signals, strategies), the publisher, version, source, and tarball hash. om packages list --outdated is the npm outdated view, om packages show one package's field sheet, om packages update the latest version after one confirmation, and om uninstall @scope/name removes what a package made here and its copy after a card naming each object. /packages in om chat is the same ledger with update and uninstall keys; an alert a package made carries a from @scope/name@version row in /alerts.

Changed

• om install on an installed package updates it. The same name at a newer version goes through the first install's path: an Indicator's copy is swapped and its alerts keep their pins, and the older copy retires once nothing living pins it. The same version with the same content answers "installed and up to date" and writes nothing. --replace stays for scripts. The update and uninstall cards bind the yes to the exact versions and objects they showed.

v0.200.0 (2026-09-02)

Fixed

• --version on om wrun remove and om wrun upgrade takes a value. Both used to print the CLI version and exit instead of reading the flag; the root now stops scanning for its own -v, --version at the first subcommand. om --version and om -v are unchanged.

v0.193.1 (2026-08-31)

Fixed

• A preview is not a placement. om chart indicator preview and the agent's chart_indicator_preview say so in the description and in the result note: the line is ephemeral, and mounting a package on a workspace is om chart indicator add.

v0.191.1 (2026-08-31)

Fixed

• A range with colors and no color_by validates. Two entries paint the band by the pair's per-bar orientation (the first where upper plots above lower, the second where it plots below); one entry paints everywhere. This matches what the chart host always rendered for the form; the conformance corpus pins the acceptance, and every other range refusal (color_by pairing, ladder caps, unknown outputs) is unchanged.

v0.180.0 (2026-08-30)

Added

• Indicators can declare everything kScript (legacy) can draw. Four additive fields close the visual gap an engine-confirmed audit found: text and label renderers take color and size; a bgcolor renderer tints per-bar backgrounds behind a firing gate, with an optional per-bar color ladder; sheet-level ranges declare true bands (an upper and lower pair with edge width, edge line style, smooth, and ladder tinting), the presentation sibling of fills; and outputs take width_by plus widths for per-bar line-width ladders. All four are code-first declarable (render.bgcolor, range(...), output and renderer options), every refusal is named, every ladder follows the engine's floor-and-entry-0 rule with non-finite values producing nothing, and the cross-host conformance corpora carry accept and reject cases for the whole surface. Existing packages parse and behave byte-identically.

v0.173.0 (2026-08-29)

Added

• The parity program closed: 167 of 177 eligible registry indicators proven bit-exact as Indicators. The last nine fetchable families were ported and matched with a deviation of exactly 0 at every gated comparison record, after which the registry census was exhausted; the remaining 90 families are custody-held and verified against an independently rebuilt census snapshot. Across the program (219 frozen families, every port frozen and rebuild-proven before its holdout windows were captured), the 10 indicators outside the tally carry machine-typed causes, none a math divergence. Tranche 6 (33 of 35 bit-exact over 40 families) rode the v0.172.0 cut without an entry of its own.

v0.171.0 (2026-08-29)

Added

• Sided liquidations, a dense grid for sparse feeds, and a declared plot offset. An input on liquidations accepts side: "BUY" | "SELL" (absent means the per-bar total of both sides), so long and short liquidation Indicators are expressible. missing accepts "zero" beside "carry" and "nan", and on the PRIMARY input "nan" and "zero" densify a sparse feed (a liquidations-only package included) onto a dense interval grid whose phase is derived from the fetched rows, with named refusals for empty or mixed-phase fetches, metric composition sources, and session grids that shift with daylight saving. Outputs accept displacement_bars (the value at bar i is displayed at bar i + N), carried through the sheet and the render selection, honored by the parity comparator, and refused by name in chart previews until the chart wire carries it. Code-first input() and output() declare all three. The per-package renderer cap rose from 16 to 32; the 2 MiB expanded-result refusal stays the resource guard.
• Parity tranche 5 and the re-port wave. Forty more registry families ran through the factory (30 of 33 eligible bit-exact across the dev window and both post-freeze holdouts), and the ten previously failing rows were re-ported on the new primitives: all ten convert with zero divergent cells, the Ichimoku lagging span proven under a preregistered displacement alignment. Cumulative: 126 of 133 eligible registry indicators bit-exact across 170 frozen families. The porter cheat sheet and the reproducible harnesses ship in-repo under tools/parity/.

v0.169.0 (2026-08-28)

Added

• The parity factory. The machine that measures a kScript (legacy) indicator against its Indicator port shipped with its first frozen experiment: ten registry indicators frozen by name, version, and hash before porting, each rewritten as a code-first package on the second ABI and compared against the real engine over a dev window, two holdout windows captured only after the ports were frozen, and metamorphic variants. Nine of ten matched with a maximum deviation of exactly 0 on every comparable cell (Wilder RSI, 900-bar EMAs, CVD, and order-book pressure included); the tenth matched numerically and diverged only on liquidation long/short text, a data-plane gap closed in v0.171.0. Two runtime features rode along: an input source may declare missing: "nan" so a sparse secondary delivers NaN instead of carrying forward (absent keeps the old behavior, byte-identical), and compute callers may pass an explicit windowBars.

Changed

• om metric get no longer requires a venue for registry metrics: an omitted --exchange resolves the coin's default listing. An Indicator metric with no venue named is refused rather than defaulted, because its source book (funding, open interest, candles) is the package's to state; name the venue for Indicator metrics.

v0.167.0 (2026-08-28)

Added

• Indicators read footprints and books, write text, and draw. (Recorded under v0.168.0 in the full changelog; shipped in this cut.) Celled source classes fetch live and exact-join the primary grid: volume_profile serves each bar's per-price [low, high, buy, sell] cells and book serves block_size-faceted [price, size, side] cells (om block-sizes lists a venue's widths). finalize() writes byte-capped per-bar text through generated str_<slot> senders; sheets declare renderers (text, label, table, shape, stats_row) and drawings (line, box, polyline, label) selected under one cross-host lifecycle with an accounted 2 MiB cap, and the chart backend vendors the same conformance corpus and parity fixtures so both hosts agree verdict for verdict. Code-first declarations cover the whole vocabulary (input("profile", volume_profile.cells, ...), string(), render.*, draw.*), and the vp-buy-share-codefirst template scaffolds a working footprint Indicator in 20 non-blank lines. The first ABI stays frozen and byte-identical; backtests and screens refuse celled packages by name (wrun_celled_metric_unsupported) and name the consumers that do support them.

Changed

• Authoring has its own skill. The authoring loop, the sheet dialect, input pins, bindable odds inputs, and chart styling moved out of the marketplace skill into a bundled authoring skill served index-first; the marketplace skill keeps install, mount, bind, repoint, remove, and publishing.

v0.165.0 (2026-08-27)

Added

• The second ABI. abi_version in the sheet selects the runtime contract (absent means the frozen first ABI, wrun-1). Modules on wrun-2 read per-bar cell blocks through wrun_arg_len and wrun_arg_bytes with exact, statically validated signatures, max_cells enforced as a named refusal, and a packed transferable worker transport in both directions (no structured clone). In this cut celled packages installed with a named warning and their metrics refused with wrun_cells_unavailable; the celled data lane followed in v0.167.0.
• Code-first authoring. Declare params, inputs, and outputs in the typed source (param, input, output from ./sdk/declare); the build derives the sheet (generated_from plus source_digest) and the accessors from one staged pipeline, scaffold version 3 migrates existing workspaces non-destructively, and the sma-codefirst template authors a moving average in 14 non-blank lines. Sheet-first authoring is unchanged.
• A performance and parity rig. A required direct-versus-worker bit-identity test over a committed module fixture, a benchmark with recorded dispersion and environment, a performance baseline with an advisory regression comparator (docs/PERF_BUDGETS.md), and an advisory CI lane. The packed transport measures 0.29 microseconds per bar in the worker, a 3.3x ratio over direct calls, down from about 10x.
• Probe-verified docs. docs/indicators/ (getting started, the SDK and sheet references, sources, styling, publishing, the kScript port guide), generated into docs/llms-full-indicators.txt and the skill's teaching regions by one writer; every fenced sample compiles through the real build in CI.

v0.160.0 (2026-08-27)

Fixed

• Agent-authored sheets validate up front. The agent's wrun_author tool validates its metadata argument against the package schema before writing, part of the turn-context lifecycle work that also sanitizes provider failures and refuses oversized tool arguments early.

v0.158.0 (2026-08-26)

Added

• Lower-pane previews. om chart indicator preview accepts panel: "lower" outputs: the wire's series gains an optional panel field (absence keeps the price-pane overlay byte-identical), and preview-aware chart frontends render the line in its own sub-pane with its own y-range, where momentum-class values are readable.

Fixed

• Previews report their drawn value range. An overlay preview shares the pane's price axis, so a 0..1 output on a price pane draws off-screen; the receipt now carries valueRange (min, max, last finite value, trailing-null count) and the note says to compare it with the pane's scale instead of claiming a visible line.

v0.155.1 (2026-08-24)

Changed

• Refusals name the alternative. An import rejection lists the runtime's legal import set and how to declare a host call (@external("wrun", "<name>")). om chart indicator add refuses an unpublished package up front with wrun_add_unpublished (the hosted chart mounts packages by registry reference, so a local install used to fail only at render time), pointing at om chart indicator preview for local drafts or publish-then-add; a registry install made before install receipts existed reads as unproven, and the message names the --replace reinstall that stamps its receipt.
• An Indicator value's age counts on the package's own bar grid, and om metric screen renders data_age_seconds in text the way om metric get does.

v0.154.0 (2026-08-20)

Added

• Bindable Indicators preview and author on the first try. om chart indicator preview gains a repeatable --bind sharing om metric get's parser (the agent's tool accepts sourceBindings), validated before any workspace call or data fetch, so an unpublished bindable draft draws through local compute; the receipt echoes the resolved binding, because the drawn odds line is not self-identifying. The agent's wrun_author ships the exact bindable-odds sheet shape as a validated example, and the skill teaches the follow-up: ask the market, prove a value with a bound om metric get, then the alert.

Changed

• Bindable-package limits are enforced in code, not prose. om chart indicator add refuses bindable packages with a typed error (the hosted overlay carries no market binding, so a mounted one would never compute), and om wrun source set refuses to repoint a bindable input before touching the sheet; it previously wrote first and validated after.

v0.153.0 (2026-08-20)

Changed

• Previews persist server-side. Indicator previews, Strategy Tester panels, and event pins live in the platform's payload store, so the chart tools stop warning about viewers whose daemon is off; the daemon's re-push remains a cache that heals a missed store write.

v0.150.0 (2026-08-19)

Added

• One package, any market. An odds input can declare binding: "required" instead of hard-wiring a Polymarket market at authoring time: the market (a conditionId, with an optional YES or NO outcome) arrives per use, as sourceBindings beside params on alert and signal operands and metric queries, or as om metric get --bind input=0x.... Publish refuses odds inputs still pinned to the template's placeholder conditionId, which computed zero rows forever.

Fixed

• Previews survive restarts and joins. Indicator previews persist before broadcast and replay to viewers who join later.

v0.149.0 (2026-08-18)

Added

• A commissioned draft installs itself. The agent's wrun_build installs the draft it authored (idempotent across rebuild loops) and returns a receipt with the one-command undo, instead of asking you to install your own artifact. Registry installs stay approval-gated; publish is unchanged.

v0.147.0 (2026-08-18)

Fixed

• A failed compile no longer wedges the agent's authoring loop. A bad build used to leave its broken artifact behind, and every later wrun_author call re-validated the stale file and threw a misleading missing-export error at once. Authoring validation treats a bad artifact as a warning (the source is the authoring truth), the build runner deletes artifacts on a compile or export-validation failure, and the missing-export error lists the artifact's actual exports and restates the four-export contract.

v0.138.0 (2026-08-16)

Fixed

• om chart indicator preview prints the chart URL and states the ordering that mattered at the time: open the chart before pushing, because previews broadcast live and did not replay to late joiners (v0.150.0 added the replay).

v0.135.0 (2026-08-16)

Added

• om chart indicator preview: draw an unpublished Indicator on a chart. The daemon computes ONE output of any locally installed package (drafts from om wrun install included) and pushes the finished series to a chart pane as an ephemeral preview line: no publish, no run authorization, no server compute. The preview is pinned to the pane's symbol and interval at compute time, so viewers on any other interval see a stale badge, never a recomputed line. One preview per pane: re-running replaces it, --clear removes it, a reload clears it. Typed refusals name the remedy: a bare package reference (a preview draws exactly one output), non-line outputs, chart-only or unserved intervals, packages whose primary input pins another interval, unattached workspaces, all-warm-up windows.

v0.134.0 (2026-08-16)

Added

• Yanked packages disclose, never disable. A publisher yanking a package your alerts pin cannot switch those alerts off (a remote disable would be a griefing lever); the daemon sweeps the registry daily over the fleet's pins, pushes one durable notice per yanked version, and om alert list and om doctor carry the disclosure from the cache. Installed copies keep evaluating.
• Cross-symbol input pins are taught. Packages could always read a fixed reference market on a secondary input (symbol + exchange on an input source); the skills, wrun_author, and the docs now teach the capability and its safe shapes. The guidance at the time fenced interval pins off; the as-of-close join that makes a coarser pin safe landed later and is the rule Script definition documents today. Zero engine changes.

v0.127.0 (2026-08-15)

Added

• kScript (legacy) packages open on charts by reference. om open @scope/name resolves a registry kScript package to its platform script id and opens the chart with the indicator applied (--print for the URL only), and om chart indicator add --type @scope/name places it on a live workspace chart. Nothing installs or executes locally; the publishing guide states the rule for choosing between a kScript package and an Indicator.

v0.123.0 (2026-08-15)

Fixed

• Indicators plot as themselves from chat. Asking the agent to put a marketplace Indicator on the chart no longer walks the picker through "Simple Moving Average", and the tool contract says one add mounts the whole package (every renderable output), so agents stop stacking one overlay per output.

v0.117.0 (2026-08-14)

Added

• Missed alerts fire late instead of never. After downtime the runner re-evaluates the unseen closed bars (up to 7 days) with the cooldown, once-mode, and edge-debounce gates applied at each bar's close; the gap digest reports what could not be verified, Indicator legs included, because an Indicator's metric history is not replayed for the catch-up.

v0.111.0 (2026-08-13)

Added

• Indicators can read the clock. Modules receive each bar's open timestamp as a host-supplied input (the time source, field bar_open_sec), so calendar and session logic (day-of-week gating, session windows, anchored levels such as a prior session's close) is expressible inside the sandbox, deterministically: live evaluation and backtest replay see identical series.

v0.27.0 (2026-07-30)

Fixed

• Closed bars follow the venue's clock. An Indicator operand in a bar-mode strategy used to classify bars by the Unix epoch's phase, so on venues whose week opens on Monday a still-forming weekly bar was folded in as if it had closed, a live look-ahead carried inside the module's state. A bar is now closed once its own full interval has elapsed, the strategy evaluates each bar exactly once on the bar the venue delivered, and a package whose primary input pins a different interval than the signal contributes no bar identity rather than a mis-gridded one. Backtests are unchanged by construction.

v0.12.0 (2026-07-23)

Fixed

• A hung metric fetch cannot wedge a strategy's exits. Metric fetches, Indicator packages included, are bounded by OM_DEADLINE_METRIC_FETCH (30 s by default); an Indicator composition chains at most four packages, and on expiry the chain is aborted, the exit check still runs, and the tick records metric_timeout naming the knob.

v0.4.0 (2026-07-10)

Added

• Backtests replay installed Indicators. om backtest spec --strategy-slug replays a saved strategy through the live decision core against a simulated venue; bar-mode metric signals, installed Indicator packages included, resolve against their save-time package_locks and replay on a bar cadence over --from and --until.
• Package visibility. visibility on every manifest: public (the default), unlisted (installable by exact name, hidden from search and the catalog), private (entitlement-gated by registry grants). om install retries a 401 or 403 with the account key it already holds, sent only to the configured registry origin, and surfaces the registry's not_entitled message plainly.

Changed

• om indicators became om metric. metric_get, metric_list, and metric_screen (and om metric get, om metric list, om metric screen) replaced the indicators_* names: price, delta_pct, volume, funding, and open interest were always supported alongside the indicator metrics, and an Indicator's outputs join the same namespace as wrun/@scope/name/<output>. The error code unsupported_exchange_for_indicators became unsupported_exchange_for_metrics.
