Release Notes

These notes summarize recorded desktop releases and identify newer workflows separately. Check Help > About before following instructions for a particular version.

Documentation Version Map

Checked September 29, 2026. This table is the shared version reference for the knowledge base, Developer Center, and course.

Evidence	Version	How to use it
Public stable update feed	1.1.23.0	The version currently advertised by that feed. Its minimum supported version is 0.9.0. Recheck the feed when downloading or upgrading.
Latest signed release in the project release record	1.1.25.0, August 20, 2026	The release notes below identify its changes. A local copy of this release's MSI had a valid HyperionX LLC Windows signature during this review; this does not establish that the current download feed distributes it.
Reviewed desktop source	1.1.27.0, snapshot 930fba77	Sections marked Reviewed 1.1.27 source explain these newer workflows. Confirm that the installed build includes the feature; the source version alone is not a public-release announcement.
Explicitly unreleased changes	No public version assigned	Migration notes remain labelled Unreleased until tied to a released installer. This includes strict bars-ago indexing.

The update feed and signed release record currently identify different versions. Use the official download path and the installed version to determine which instructions apply; do not assume every feature described for 1.1.25 or reviewed 1.1.27 source is available in a 1.1.23 installation. Preview, Beta, and Internal labels describe support boundaries independently of version numbers.

The Signed headings summarize project release records. Signature verification is not a clean-install or provider certification. Verify the downloaded installer's Windows signature and test the workflow in the intended installed build.

Before upgrading, read Install, Update, And Uninstall, back up Documents\HyperionX, stop active strategies, and close every HyperionX window and worker.

1.1.25.0 - Signed Release Recorded August 20, 2026

• Added adverse tick slippage for Validator historical Market and StopMarket fills, with persistence in strategy risk presets. This does not add an ordinary Optimizer slippage control.
• Added separate closed-trade and intrabar-equity drawdown measures, result reproducibility metadata, and optional strategy decision diagnostics.
• Recorded requested and loaded ranges, timezone, commission, slippage, session-close behavior, and continuous-futures merge settings in Validator artifacts.
• Corrected selected-secondary-series binding for V2 indicator inputs, readiness, nested indicators, and output storage.
• Improved Rithmic native-bracket journal recovery, recognition of released protection during scale-ins, retirement of stale order rows after authoritative replay, and stop trailing beyond breakeven.
• Improved Validator date-range selection, summary export responsiveness, and preset persistence.

See Backtesting, Performance Database, V2 Script API, and Connection Recovery.

1.1.23.0 - Signed Release Recorded August 12, 2026

• Preserved native-bracket journal field names in protected builds so saved ownership remains readable after restart.
• Restored ownership of recovered native brackets and local attached-OCO handling for Hyperion Sim using Rithmic data.
• Kept SuperDOM Hyperion Sim orders on local OCO management.
• Aligned packaged Research Worker output with the release version.

1.1.22.0 - Signed Release Recorded August 12, 2026

• Serialized Rithmic bracket changes and reconciliation around provider-confirmed state.
• Improved attached protection sizing after scale-ins and reductions, partial-close handling, and flatten recovery.
• Added points-based chart PnL and a clickable PnL badge.
• Improved chart loading, dark property editors, dialogs, and trade-sound feedback.

1.1.21.0 - Signed Release Recorded August 10, 2026

• Removed fixed chart-history replay cutoffs in favor of the documented Rithmic completion callback, while preserving cancellation and manual disconnect.
• Preserved the chart viewport after Windows session recovery and scaled volume panes using visible bars.

1.1.20.0 - Signed Release Recorded August 7, 2026

• Added a date-order preference used across charts, grids, reports, dialogs, and research results.
• Added horizontal chart-history navigation and multiple Code Lab document tabs.
• Added navigation from Code Lab diagnostics to the source location.
• Improved Rithmic protective-order mutation sequencing and customer-facing rejection messages.

1.1.19.0 - Signed Release Recorded August 6, 2026

• Stopped automatic Rithmic reconnect loops after failed login or unexpected disconnect; another attempt requires manual retry.
• Consolidated market data, trading, PnL, and history into one Rithmic connection lifecycle.
• Added connection-state colors for disconnected, connecting, connected, and failed states.

1.1.18.0 - Signed Release Recorded August 5, 2026

• Added import/export packages for supported Code Lab items, with multi-item selection, optional dependency discovery, validation, and safe destination handling.
• Added trade execution sounds while suppressing sounds for replayed recovery fills.
• Improved attached-OCO sizing, order sequencing, instrument switching, and history recovery.

1.1.17.0 - Signed Release Recorded August 4, 2026

• Added a dedicated Flatten operation that cancels working orders and closes the instrument position with broker confirmation.
• Distinguished Close's position/protection scope from Flatten's additional cancellation of independent resting entries. See Chart Trader for provider-specific and newer-build behavior.
• Added customer-accessible Help > Export RAPI Logs.
• Improved restored-order cancellation, open-order reconciliation, order identifiers, and chart controls.

1.1.16.0 - Signed Release Recorded July 30, 2026

• Added a focused Rithmic futures quick-load catalog and improved current-contract selection.
• Added offline workspace chart restoration from durable historical cache and reconnection to a compatible provider.
• Improved chart loading messages, concurrency, and packaged executable checks.

Reviewed 1.1.27 Source

These additions are documented for the reviewed source snapshot; confirm their availability in the installed package:

• Export-history selection, with a three-hour default for new settings and preservation of existing saved choices.
• Grounded Cloud Rion conversations, pasted-image support, owned-indicator creation and compilation, and Delete all conversation reset.
• Installer download and verification, minimum-version startup enforcement, one-for-one Chart Trader reversal, and confirmed simulation-account reset.
• Newer Marketplace publisher controls and workspace restore behavior. A visible control does not by itself promote an Internal or Preview feature to a supported public workflow.

See the corresponding task pages for version notices and limitations. The strict-indexer migration remains explicitly unreleased.

1.1.12.0 - Signed Release Recorded July 23, 2026

Strategy API and historical execution

• Added an opt-in V2 strategy facade for selected-series indexing while preserving existing script behavior.
• Added versioned indicator entry points with isolated runtime and cache identities.
• Corrected selected-series behavior for versioned indicators, including ATR, EMA, and session VWAP behavior recorded for this release.
• Improved synchronization and OCO handling for managed strategy stop-loss and profit-target orders.
• Populated historical unrealized PnL consistently in strategy, position, and context views during callbacks.

Use the V2 Script API to create new scripts or convert code you own or have permission to modify. Its examples are synthetic, generic, and limited to the public API contract.

The project changelog records this release as protected with .NET Reactor NecroBit and signed with Trusted Signing. It also records the Python Research Runtime and WebView2 prerequisite initialization in the MSI. Independently verify the exact installer you download.

1.1.11.0 - Signed Release Recorded July 22, 2026

Platform, research, and connection foundations

• Added persistent Hyperliquid wallet and agent-wallet connection state, including builder-approval recovery work.
• Added product-owned defaults and runtime bridges for bundled strategies, indicators, optimizers, fitness functions, money management, commissions, bar types, and add-ons.
• Prevented historical Validator, Optimizer, and related strategy-evaluation paths from routing simulated orders to live provider accounts.
• Improved custom-script seeding and compilation for the protected installer.
• Added the first secured Marketplace publishing and following implementation; Marketplace remains outside the supported public surface until its status page promotes it.
• Improved chart stability and scoped Rion conversation and chart-grounding behavior.

The project changelog records this release as protected and signed, with the validated Python Research Runtime and WebView2 prerequisite initialization in the MSI. Independently verify the exact installer you download.

1.1.10.0 - Signed Release Recorded July 22, 2026

Trading and connections

• Improved Rithmic connection routing, reconnect behavior, historical continuity, and bracket-order tracking.
• Kept independently submitted Rithmic OCO groups separate and preserved their contract quantities during fill and cleanup processing.
• Added continuous-contract history support for research while retaining resolved tradeable futures contracts for order entry and depth.

Charts and market data

• Improved live-chart continuity and gap recovery.
• Added provider-aware top-of-book fallback rendering in MegaDOM when full depth is unavailable.
• Improved chart resizing, timer styling, and Rion avatar visibility controls.

Top-of-book fallback is not the same as a complete depth book. See Market-Data Tools before using depth displays in a trading decision.

Rion and research

• Improved Rion agent selection, restoration, labels, chart actions, and research handoffs.
• Preserved requested instrument, timeframe, history window, job identity, and strategy intent across Research Lab, Strategy Finder, Validator, and Optimizer handoffs.
• Added a minimum of 30 completed trades before Python prescan candidates can be promoted automatically.
• Kept local Research Lab worker execution away from the desktop UI path during long scans.

Research availability and reproducibility limits are documented in Research Lab, Backtesting, and Performance Database.

1.1.9.0 - July 17, 2026

• Improved KuCoin instrument identity, historical pagination, live-candle continuity, order preflight, reconciliation, rate limiting, and depth recovery.
• Improved Rithmic manual disconnect and reconnect behavior.
• Restored editing of indicator plot appearance settings.
• Added WebView2 prerequisite initialization to the primary Windows installer.
• Hardened installer upgrades so companion processes are stopped before files are replaced.

1.1.8.0 - July 17, 2026

• Prevented a manual Rithmic disconnect from entering an automatic reconnect loop.
• Moved native Rithmic shutdown work away from the UI thread.
• Restored chart loading after a Rithmic reconnect on the chart's owning UI thread.

Compatibility Notes

• Custom extensions must be rebuilt with the target desktop version and tested in simulation after an upgrade.
• A successful application upgrade does not prove that a saved workspace, provider entitlement, or third-party extension is compatible.
• Provider behavior can change independently of HyperionX. Recheck permissions, environments, order types, and recovery behavior before returning to live use.
• Features labeled Preview, Beta, Internal, or Unavailable are not promoted by the existence of code or a visible menu entry. Use Feature And Provider Status as the public availability source of truth.
