RangeScout 1.6.4

RangeScout 1.6.4

RangeScout 1.6.4 is a narrowly scoped Windows startup hotfix. It preserves the RangeScout 1.6.3 watchlist correction and the existing workstation behavior.

Windows startup correction

RangeScout now launches successfully on the clean Windows configuration validated by Independent QA. The failure was caused by PyInstaller collecting a package-local icuuc.dll that shadowed the Windows ICU compatibility DLL required by Qt. When QtCore attempted to load, the bundled ICU library did not provide the required compatibility procedure.

The 1.6.4 release pipeline removes that prohibited shadow DLL and fails closed if dependency collection introduces it again. The Windows build environment is reproducibly pinned across Python, Qt/PySide6, Shiboken, PyInstaller, and PyInstaller hooks. Packaging also audits critical runtime files, rejects duplicate or conflicting QtCore runtimes, launches the frozen executable as a build gate, and ensures installer upgrades replace the previous internal runtime tree.

Independent QA verified both a clean fresh install and an in-place upgrade from public RangeScout 1.6.3 to 1.6.4. The upgrade removed the stale ICU file, produced the same runtime inventory as the clean install, preserved user AppData, and retained the 1.6.3 selected-watchlist, single-symbol Add/Remove, Active Symbol quick-add, watched-state, ticker/runtime, and scanner refresh fixes.

Watchlist hotfix

• Selecting a watchlist now persists it as the current target and no longer fills the single-symbol input with every member.
• Add Symbol and Remove Symbol operate on one normalized canonical symbol, remain duplicate-safe, and refresh dependent watchlist, ticker, scanner, and runtime state.
• Invalid watchlist or symbol actions now produce clear user-visible warnings.
• The Active Symbol context shows Add to Watchlist or Watchlisted, targets the selected list reliably, creates My Watchlist when necessary, and updates immediately when the Active Symbol changes.

RangeScout 1.6.3 preserves the released 1.6.2 market-data, SEC Research, provider-routing, local-first storage, Live Trader, scanner, alerts, notes, exports, system-tray, and installer behavior.

RangeScout 1.6.2 Release Notes

RangeScout 1.6.2 is the current Windows release from Dietrich AI Labs.

Major highlights

Smarter instrument search and identity

• Adds deterministic canonical instrument identity across Market, Research, discovery, and provider routing.
• Gives exact tickers precedence while improving ranked company-name search, punctuation normalization, historical aliases, and disambiguation.
• Expands supported security semantics across equities, funds, preferreds, ADRs, warrants, rights, units, ETNs, indices, partnerships, and related structures.
• Reconciles official discovery updates without casually destroying identity or listing history, and rejects incomplete official-source refreshes rather than treating them as removals.

Better market and provider routing

• Improves fused quote/history presentation, immediate Active Symbol transitions, and rejection of stale background results.
• Routes canonical instruments through provider-specific symbols and explicit capability checks across the broader catalog.
• Preserves the reserved visible-quote priority lane so slower history, Research, scanner, news, and logo work cannot starve the quote currently on screen.
• Shows unsupported, unavailable, cached, delayed, and offline states explicitly instead of fabricating a route or value.

Stronger Research and fundamentals

• Routes corporate issuers, funds, and other market instruments through appropriate Research paths.
• Improves preferred, partnership, LLC-unit, IFRS, US-GAAP, taxonomy, currency, and reporting-regime handling.
• Keeps legitimate missing or incomparable facts visible as unavailable or N/A.

SEC filing and fiscal-period accuracy

• Separates quarterly, year-to-date, annual, transition, and instant facts deterministically.
• Reconciles partial amendments/restatements per metric and stabilizes quarterly growth comparisons.
• Separates fiscal identity from calendar frames, treats fy + fp atomically, and uses frame-only fallback only when appropriate.
• Adds deterministic SEC best-alignment handling for off-calendar and 52/53-week reporters while continuing to reject wrong adjacent frames.

Reliability, persistence, and installer behavior

• Expands migrations and idempotent schema recovery while keeping reference seeding deterministic.
• Preserves notes, settings, local state, AppData, and exports through the supported lifecycle.
• Verifies the supported 1.6.1 → 1.6.2 upgrade path and confirms uninstall remains limited to RangeScout-owned install scope.
• Broadens regression and package-integrity coverage across discovery, routing, classification, Research, SEC periods, persistence, packaging, upgrade, and uninstall behavior.

RangeScout preserves its local-first workstation, system-tray operation, company/logo database, Live Trader, SEC fundamentals, scanner, alerts, watchlists, notes, exports, provider diagnostics, and secure user-supplied credential storage.

Windows may display a reputation or security warning because the installer is not publicly trusted Authenticode-signed. Verify the published SHA-256 before installation if desired.

Availability and disclosures

• Market and provider availability, coverage, latency, and entitlement vary.
• Public sources do not all require credentials; some enhanced providers require credentials supplied by the user for the applicable free or eligible account tier.
• Supported credentials are stored through Windows Credential Manager; no shared Dietrich AI Labs provider key is embedded.
• When legitimate provider data is unavailable, RangeScout displays an unavailable or N/A state rather than fabricating a value.
• RangeScout is an informational and analytical tool. It does not provide investment advice and does not execute trades.
• No public simulated-data provider or deferred brokerage provider is exposed.
