Release history

Changelog

A concise record of public features, scientific data releases, corrections, and selected literature additions. Release dates show when a version became public; paper dates show when each source entered the Atlas, not when the source paper was published.

v0.6.11Current10 Sept 2026

Public model execution availability, 141-simulant directory & viscosity models showcase

Enabled public model execution for hosted deployments, integrated the complete 141-simulant catalog sorted by linked literature citations into the modelling workspace, and prominently surfaced all 13 individual viscosity models with search indexing.

Changes

Correction

Public model execution availability

Enabled the modelRuns launch feature by default across hosted environments and permitted public anonymous calculations on /api/models/run with IP-based rate limiting.

Feature

Full 141-simulant directory ordered by literature

Populated the simulant selector with all 141 simulants from the database snapshot ordered descending by linked literature paper count, with seamless manual oxide entry fallback for uncharacterized materials.

Feature

Prominent viscosity calculation models showcase

Surfaced all 13 high-temperature viscosity methods (Shaw 1972, Giordano & Dingwell, Hui & Zhang, GRD08, Duan, Sehlke, Langhammer, Visc_Calc, i-melt) with color-coded badges, descriptions, and full search indexing.

v0.6.1010 Sept 2026

Modelling workspace layout overhaul & unified catalog alignment

Modernized the property modelling workspace layout to align with the literature and simulant directories, adding real-time model search and filtering, compact segmented family navigation, and responsive quick-action calculation triggers.

Changes

v0.6.910 Sept 2026

Public modelling workspace availability & resilient session error handling

Restored public visitor access to the property modelling workspace by removing restrictive layout gating, converted the modelling workspace to standard static imports, and hardened server session resolution and runtime composition loading with resilient database fallbacks.

Changes

Correction

Public modelling workspace availability

Removed access restriction layout gating on /modelling so visitors can use the client-side thermophysical property calculators directly without encountering 500 error boundaries.

Correction

Server session database error resilience

Wrapped userFromToken in resilient error handling so database connection drops or unconfigured PostgreSQL environments gracefully return anonymous state rather than throwing unhandled exceptions.

Feature

Modelling page import & snapshot resilience

Switched ModellingPage to standard top-level imports and added safe fallbacks to loadRuntimeCompositionRecords ensuring seamless offline and serverless operation.

v0.6.89 Sept 2026

Property modelling workspace, header quick search & static homepage

Promoted property modelling into the main navigation, homepage modules, and public sitemap, integrated a global quick search trigger in the site header, pre-rendered the homepage for instant loading, and consolidated literature submissions under /literature.

Added Modelling to primary navigation and homepage modules, enabling visitors to freely explore property models, thermophysical calculations, and benchmarks across categories.

Feature

Header full search bar & live suggestions

Added an interactive full search bar directly next to About in the header navigation with live autocomplete suggestions, keyboard navigation, and shortcut triggers (/ and Ctrl+K).

Correction

Static homepage pre-rendering

Pre-rendered the homepage statically for instant page loads and optimal delivery performance.

Correction

Literature submission consolidation

Consolidated community literature submissions directly within the Literature catalog with automatic redirection from legacy paths.

v0.6.79 Sept 2026

Uniform directory layout & simulant ask action

Standardized the Simulants directory layout to match the single-column horizontal header and filter toolbar of Literature, and added the 'Ask the simulants' action button.

Changes

Feature

Uniform directory header & horizontal filter toolbar

Replaced the legacy 2-column sidebar layout in /simulants with a single-column horizontal header and filter toolbar matching /literature, including clean responsive search and select filters, inline count definitions, and matching loading skeleton.

Feature

Ask the simulants action button

Added an 'Ask the simulants' action button to the Simulants directory header linked to /ask, matching the 'Ask the literature' button in /literature.

v0.6.69 Sept 2026

About CV presentation & layout polish

Polished career highlights and section formatting on the About CV page for improved readability and responsive presentation.

v0.6.59 Sept 2026

Catalog terminology alignment: extracted evidence & property data

Aligned user-facing terminology across research coverage, simulant directories, and literature views to accurately describe extracted evidence and property labels, ensuring clear distinction between automated quality filtering and human reviewer acceptance.

Changes

Correction

Extracted evidence & property terminology alignment

Replaced misleading 'accepted' references across public research coverage ('papers with extracted evidence'), simulant directory count badges/headers ('extracted property labels'), and literature detail panels ('extracted property evidence') with precise 'extracted' descriptions.

v0.6.49 Sept 2026

Landing page asset & media optimization

Optimized 3D Moon hero media assets, significantly reducing transfer payloads and improving initial page delivery speed.

Changes

Correction

Media asset delivery optimization

Streamlined landing hero animation delivery to modern WebM and WebP formats, substantially reducing page bundle transfer size.

v0.6.38 Sept 2026

100 wt% anhydrous chemical composition normalization & LOI volatile separation

Added interactive 100 wt% anhydrous normalization toggle for major-element simulant chemistries. Excludes terrestrial volatile loss (LOI) from the normalization denominator to reflect anhydrous lunar regolith stoichiometry and enables direct comparative petrology across research publications.

Changes

Feature

100% Anhydrous normalization toggle

Added an interactive segmented toggle ('As reported' vs '100% Anhydrous') to the Chemical Composition matrix. Normalizes comprehensive whole-rock primary oxide suites to sum to exactly 100.00 wt% with dynamic 'wt% (norm)' column header indicators.

Data

Loss on Ignition (LOI) volatile separation

Strictly excluded Loss on Ignition (LOI) from the 100 wt% normalization denominator so that terrestrial volatile loss (absorbed water, carbonates, bound moisture) does not artificially depress silicate stoichiometry when comparing to volatile-free lunar regolith.

Feature

Calculation transparency & method diagnostics

Exposed per-cell normalization formulas, raw measured values, measured oxide sums, and exact scaling factors in hover tooltips and expanded row details per the system transparency contract.

v0.6.28 Sept 2026

Literature extraction terminology clarification & curation transparency

Updated literature browser counters, filter facets, and sort options to explicitly indicate extracted direct values and properties, ensuring pipeline characterization metrics are never conflated with human reviewer verification.

Changes

Correction

Extracted direct values terminology

Renamed literature browser card summaries, sort options, and filter facets from 'accepted' to 'extracted direct values' and 'extracted properties' to make clear that programmatic quality filtering is distinct from human reviewer sign-off.

v0.6.18 Sept 2026

Chemical composition matrix row consolidation & analytical method preservation

Consolidated transposed chemical composition matrix tables across analytical sub-clauses (such as bulk chemistry vs loss on ignition in Long-Fox 2023 for LMS-1D), ensuring whole-rock oxides and volatile LOI unify into a single comprehensive row while preserving primary analytical methods.

Changes

Correction

Transposed composition row consolidation (LOI & bulk chemistry)

Extended row grouping context normalization in transposed tables to harmonize analytical subcategory qualifiers (e.g. bulk chemistry in equivalent oxides vs loss on ignition), eliminating fragmented duplicate rows with empty dashes and unifying measurements into one cohesive row per publication.

Feature

Primary analytical method prioritization in pivoted composition tables

When consolidating multi-analyte rows where an auxiliary test (such as loss on ignition) is reported alongside the primary bulk analytical method (such as fused bead XRF), the display row preserves and displays the primary characterization method in the row details.

v0.6.08 Sept 2026

Literature intelligence, dynamic simulant filtering, and UI transparency

Interactive simulant filtering and PDF previews across literature, detailed loading indicators with live execution feedback, community paper submissions, and provenance-aware document status.

Changes

Feature

Literature simulant filtering & PDF thumbnail previews

Visitors can filter literature directly by detected simulants and materials with dynamic frequency counts, browse visual document previews, and navigate into categorized research collections.

Feature

Transparent detailed loading indicators

Multi-step operations, searches, and reanalyses now display step checklists, elapsed timers, model badges, and progress counters across the Atlas interface.

Feature

Community literature submissions & intake pipeline

Users can submit missing papers and PDFs directly from literature views, feeding a unified multimodal extraction and review workflow.

Feature

Author-year literature citations with title hover tooltips

In-text citations across Ask syntheses now format cleanly as author and year (e.g. (Beall, 1992)), display the full paper title on mouse hover tooltips, and reliably link to all catalog literature entries regardless of DOI availability.

Correction

Provenance-aware document missing status

The document submission callout now checks whether extraction was derived from a local PDF, suppressing false-positive missing document banners for extracted literature on public snapshots.

v0.5.420 Aug 2026

Launch performance, privacy, and data-quality hardening

The public launch surface now uses bounded route payloads, fail-closed operational APIs, and a freshly audited scientific snapshot.

Changes

Correction

Compact database and comparison routes

Properties and Methods page on the server, Simulants uses a compact directory projection, and Comparisons loads bounded view-specific summaries instead of transferring every raw row.

Correction

Public data and API privacy boundaries

Anonymous Literature uses strict bibliographic projections, while raw measurements, tables, extraction details, derived records, stored PDFs, and model operations require an approved or reviewer account and return private no-store responses.

Correction

Scoped credentials for automation

Independent machine workflows now use named, method-and-path-scoped service credentials, while human administrators continue to use individual accounts; the former universal admin-secret cookie flow is retired.

Data

Verified citations and scientific display repair

The refreshed snapshot contains 1,357 publishable papers and 32,510 scalar rows; exact-registry and official-source citation corrections are serialized, 57 unresolved or duplicate identities are quarantined, scientific symbol corruption is repaired at read time, and all 32,510 value/unit pairs render without duplicated units.

Release data

Publishable literature records: 1,357
Canonical scalar measurements: 32,510
Launch-safe public property rows: 29,496
Public bibliography quarantines: 57

v0.5.320 Aug 2026

Reliable and compact Methods filters

Method-group filters now update the visible records correctly and use a compact, intersecting selector workflow.

Changes

Correction

Method filters no longer retain unrelated cards

Collision-safe row identities keep the rendered cards aligned with Method, Property family, Simulant, and search filters, while exact detail links distinguish groups whose legacy slugs collide.

Feature

Compact applied-filter workflow

Large filter chip walls are replaced by compact selectors with contextual counts, removable applied filters, public Clear all, and a 100-row Show more window.

v0.5.220 Aug 2026

Correct paper discovery in Ask

Ask now treats explicit paper questions as literature discovery, even when the question also names a simulant and property.

Changes

Correction

Material-property paper questions route correctly

Questions such as “Which papers measured viscosity for LX-M100?” now return the confirmed paper title, year, DOI, and source link instead of applying the numerical measurement-review gate.

v0.5.120 Aug 2026

Clearer answers and normalized property values

Ask now leads with useful answers instead of internal retrieval diagnostics, while public property values, simulant rows, NASA coverage, and Literature filters are more compact and consistent.

Changes

Correction

Answer-first Ask results

Ask removes pre-submit implementation prose, raw retrieval chunks and scores, and empty diagnostic shells; successful answers now lead with concise evidence and sources.

Correction

Truthful model failure handling

Unavailable narrative generation returns a compact retry state. Actual provider attempts retain one sanitized, collapsible calculation record, while preflight failures do not claim that a model ran.

Correction

Corpus-wide value and unit display

All 31,178 bundled measurements pass through one presentation boundary that prevents duplicate units while preserving canonical numeric and unit metadata for future conversions.

Correction

Compact scientific browsing

Simulant rows omit repeated availability prose, NASA priority coverage stays fully expanded, Properties uses compact contextual details, and Literature replaces operational badges with bibliographic filters.

v0.5.019 Aug 2026

Focused scientific browsing and privacy

Public literature, simulant, property, method, and comparison views are now more compact, better filtered, and clearer about which records are actionable.

Changes

Correction

Actionable chronological literature

Literature results sort newest first, avoid repeated years, keep DOI-pending metadata records non-clickable, and remove catalog queue, tag, deletion, and warning-background clutter.

Correction

Compact simulant evidence

Simulant pages remove repeated diagnostics and exports, simplify their Literature list, and restore NASA priority rank 19 (Fatigue) from NASA/TP–2006–214605.

Correction

Direct property evidence and complete labels

Properties omits derived and citation-column copies, names composition analytes, adds simulant and source-year filters, and formats each source as Author (Year) Title.

Correction

Cleaner Methods and Comparisons

Method placeholders and generic Others suffixes are removed, method facets filter reliably, and Comparisons uses a compact control surface without repeated export or pipeline copy.

Correction

Privacy-safe legal contact

The public legal pages no longer expose a residential address or phone; deployments can provide a separate non-private service address through a server-only setting.

v0.4.019 Aug 2026

Unified Ask workspace

Ask is now a first-class header destination with guided Database, Simulant, and Literature context selection.

Changes

Feature

First-class Ask navigation

A dedicated Ask item in the global header replaces the former Database child entry and opens one canonical Ask workspace.

Feature

Guided context selection

The Ask page now provides explicit Database, Simulant, and Literature choices, including canonical simulant and paper selectors backed by the published V6 snapshot.

Correction

Preserved locked evidence scopes

Existing contextual links and legacy Ask URLs converge on the new page while server-resolved simulant and paper locks remain unchanged.

v0.3.219 Aug 2026

Transparent authentication availability

Authentication now reports account-service outages explicitly, keeps session responses private, and remains fail-closed while the service is unavailable.

Changes

Correction

Actionable outage responses

Login, registration, and session checks now distinguish a retryable account-service outage from invalid credentials, malformed input, and an ordinary signed-out session.

Correction

Private authentication responses

Authentication endpoints now prevent shared caching on every response, including errors and session-state checks.

Correction

Fewer account-store queries

Login and protected role checks reuse returned or already-loaded account records, removing redundant data-store reads without changing access decisions.

v0.3.118 Aug 2026

Resilient published paper details

Published Literature pages can continue from the immutable V6 snapshot when the live mutable record is unavailable.

Changes

Correction

Database-outage fallback

Exact published paper IDs now render from the V6 snapshot during classified data-service outages, while mutation tools remain disabled.

Correction

Visible fallback identity

Snapshot-backed paper pages identify the V6 schema and generation time and keep Ask this Paper locked to the exact snapshot record.

v0.3.018 Aug 2026

Context-aware scientific Ask

One transparent Ask workspace can now answer across the database or stay locked to Literature, one simulant, or one paper.

Changes

Feature

Ask by scientific context

Ask the Database, Ask the Literature, Ask this Simulant, and Ask this Paper reuse one grounded question-answering workflow.

Feature

Contextual entry points

Simulant profiles and Literature pages now open the Ask workspace with the relevant scientific context already selected.

Correction

Server-enforced evidence scope

Locked simulant and paper contexts are validated against the bundled public snapshot and applied before evidence is selected.

Correction

Visible and accurate execution details

Streaming progress is visible while a question runs, and deterministic answer paths no longer imply that a chat model was used.
