File	Category	Summary
`common/accessibility/images.xsl`	Transform Accessibility	New Images-Title template separating an image's tooltip (title attribute) from its alternate text A declared empty title means the author wrote no tooltip; frames with no declaration keep the historical alt-text fallback
`common/landmarks/landmarks-core.xsl`	Transform	New Landmarks-ComputeLandmarkID template honoring the per-style landmark-id-format option (hashed-16 default, hashed-8, source-id) with cross-document collision warnings; landmark paths no longer prefix anchors with `ww`
`common/links/document_unique.xsl`	Transform	Only processes link files for documents present in the target-filtered project, so documents excluded from the target no longer contribute stale link entries
`common/links/group.xsl`	Transform	Same target-filtered document restriction when merging per-group link files
`common/locale/locales.xml`	Localization	Added GroupsGridLabel string (Splash page Contents grid heading) across all locales; documented the optional CharacterFolding element for search character equivalence
`common/locale/select.xsl`	Transform Localization	Injects a default search CharacterFolding into any locale that does not declare its own Default folds curly (U+2019) and modifier-letter (U+02BC) apostrophes to the straight apostrophe (U+0027); an empty CharacterFolding element disables folding
`common/pages/popups.xsl`	Transform	Progress counter now declares the actual popup count per document, preventing counter overflow when a document contains more than one popup
`common/scripts/third-party-js.xsl`	Transform	New file — pipeline that copies bundled third-party JavaScript libraries (DOMPurify, markdown-it) from versioned Helpers into output so the AI Assistant has no runtime CDN dependency
`common/toc/resolve.xsl`	Transform	TOC entries whose paragraph generates no output now inherit the destination of the nearest linkable child entry, fixing unlinkable entries and dead breadcrumbs
`markdown/markdown-frames.xsl`	Transform	Image title attribute resolved through the shared Images-Title template (tooltip vs. alt-text separation), including the Markdown image-link path
`markdown/markdown-output.xsl`	Transform	Compresses leading whitespace so content is not mistaken for an indented code block; code-span delimiters sized to exceed the longest interior backtick run, with CommonMark space padding; code-span content emitted raw (no HTML entity escaping); intra-word underscores no longer escaped (snake_case publishes cleanly); blockquote continuation fixed to check only the immediately following paragraph's resolved syntax; code-fence continuation prefix flattened to its string value
`markdown/markdown-tables-html2md.xsl`	Transform	Note scoping fixed for nesting: only notes whose nearest enclosing table is this table are emitted
`reports/links/document.xsl`	Transform	New report-links-runtime-anchor severity: runtime hash anchors (#/, #context/, #page/, #search/) are classified at that severity in formats that declare the setting instead of always reporting as unresolved anchors
`reverb/url_maps.xsl`	Transform	Shell-only targets (Generate Groups disabled) emit the url_maps skeleton without group-derived topic, page, or baggage entries

WebWorks Reverb 2.0

File	Category	Summary
`format.wwfmt`	Configuration	Adds federated-composition capabilities (generate-empty-project, composition-transform, composition descriptor names); new ThirdPartyScripts pipeline bundling DOMPurify + markdown-it; page-templates stage gains Page/Popup template URI parameters; landmarks generation moved to format-local Transforms/landmarks-json.xsl; new descriptor.xsl stage after url_maps
`API/reverb-search.js`	Scripting	Baggage-page search highlighter now folds equivalent characters (from the wwr_cf value passed by main search) and expands highlight terms into character classes so either apostrophe form matches
`Pages/Connect.asp`	UI Scripting Accessibility	Links new css/custom.css (loaded last) on every page; loads idb-cache.js and conditional optimized-reader.js; adds draggable menu resize handle (role=separator, keyboard-focusable) AI Assistant now loads locally bundled DOMPurify and markdown-it instead of a CDN Search iframe gets tabindex="-1"
`Pages/Footer.asp`	UI	Removed the data-highlight-require-whitespace attribute from the html element
`Pages/Header.asp`	UI	Removed the data-highlight-require-whitespace attribute from the html element
`Pages/NotFound.asp`	UI	Links the new css/custom.css user-override stylesheet
`Pages/Page.asp`	UI	Links css/custom.css; loads conditional optimized-reader.js; removed data-highlight-require-whitespace attribute
`Pages/Parcel.asp`	UI	Adds warning comment only — do not pretty-print this template (a self-closed script element silently drops the parcel's topics); no functional markup change
`Pages/Popup.asp`	UI	Links css/custom.css; removed data-highlight-require-whitespace attribute
`Pages/Search.asp`	UI	Links css/custom.css; loads idb-cache.js and conditional optimized-reader.js; removed data-highlight-require-whitespace attribute
`Pages/Splash.asp`	UI	Replaces the static splash image, inline styles, and WebWorks logo/disclaimer table with a splash_groups nav container populated at runtime with group entry-point cards (Contents grid); links css/custom.css; loads conditional optimized-reader.js
`Pages/sass/_borders.scss`	Styling	New dedicated Assistant nav-button border variables (plus hover/click states); nav buttons unified on divider-on-the-right convention; new Splash groups-grid card border variables
`Pages/sass/_colors.scss`	Styling	New assistant "powered by" badge colors and the Splash groups-grid card color palette
`Pages/sass/_fonts.scss`	Styling	New Splash groups-grid card title and member font variables
`Pages/sass/_sizes.scss`	Styling	New assistant_generate flag; nav-buttons row collapses when fewer than two of index/TOC/assistant are generated; new Splash groups-grid sizing set
`Pages/sass/connect.scss`	Styling	Menu width driven by the --menu-width custom property for runtime resizing; new resize-handle styles; nav row converted to flex layout shared by assistant/TOC/index; AI Assistant chat restyled as a flat transcript with role labels, avatar-image support, streaming reasoning blocks, and a "powered by" badge
`Pages/sass/custom.scss`	Styling	New file — user customization layer compiled to css/custom.css and linked last on every page; imports the variable partials and emits no CSS itself, so projects can override it to restyle output
`Pages/sass/menu_initial_closed.scss`	Styling	Closed-menu offsets switched to calc() on the --menu-width custom property (resizable menu)
`Pages/sass/menu_initial_open.scss`	Styling	Same --menu-width custom-property conversion for initial-open offsets, page margins, and widths
`Pages/sass/skin.scss`	Styling	Menu resize handle appearance; Assistant nav button uses its own variables; last nav button drops its right divider; new Splash groups-grid card styling (accent keyline, focus outline, reduced-motion handling); new Assistant chat theming block (role labels, user bubble, avatar, bubble typography)
`Pages/sass/webworks.scss`	Styling	Responsive layout rules for the Splash groups grid inside the page iframe (narrow/tall single column, narrow padding and gap)
`Pages/scripts/assistant.js`	Scripting	AI Assistant reworked: single POST chat/stream request with hand-rolled SSE parsing and abortable streaming; structured usage-limit refusals with countdown input lockout; streaming reasoning indicator and throttled render; all rendered markdown/evidence sanitized through bundled DOMPurify; page context capped at 16KB; configurable avatar image with safe-URL validation; anonymous end-user identity tokens; optional "Powered by WebWorks" badge
`Pages/scripts/common.js`	Scripting	New Diagnostics module logging unexpected caught exceptions with subsystem/parcel context; Message.Listen separates JSON-parse failures from handler throws; new shared own-property-guarded Message.Dispatch; parcel/index post failures now logged instead of swallowed
`Pages/scripts/connect.js`	Scripting	Parcel failure tolerance (onerror/watchdog so an absent parcel cannot hang the preload spinner; failed deep-links route to not-found); progressive hydration (non-gating hashes defer remaining parcel loads to idle); IndexedDB cache integration with per-parcel search/landmark hash keys; splash Groups Grid data collection and posting; menu Default Tab support; assistant tab hidden on file:// when configured; author-chrome runtime-hash link interception; menu resizer initialization
`Pages/scripts/idb-cache.js`	Scripting	New file — shared IndexedDB cache for per-parcel search records and the book index, in a per-base-url database; queued pre-open access, unavailability fallback, cross-instance LRU bookkeeping, database pruning, and a ?ww_no_cache=1 dev bypass
`Pages/scripts/landmarks.js`	Scripting	localStorage write-through caching of landmark chunks per parcel with stale-record sweeping, an origin-wide cache budget with LRU eviction, and quota-error retry; landmark extraction widened beyond 16-hex hashes so hashed-8 and source-id landmarks (including Unicode) resolve; re-entrant-safe load; missing chunks warn instead of erroring
`Pages/scripts/menu.js`	Scripting	New draggable/keyboard-operable menu width resizer (200-600px clamp, --menu-width custom property, persisted in localStorage, ARIA value attributes, disabled in narrow layout)
`Pages/scripts/optimized-reader.js`	Scripting Accessibility	New file — Optimized reader mode (accessibility-optimized-reader-mode target setting) Suppresses tab stops and hides decorative chrome from assistive tech; adds Alt+S/M/A/C jumps, F6 area cycling, cross-frame Tab routing with end-of-page advance, arrow-key content scrolling, and Escape handling
`Pages/scripts/page.js`	Scripting	New splash Groups Grid renderer built with DOM APIs and textContent, hrefs validated via Message.IsSafeURL, layout mirroring the connect frame; dispatch switched to shared Message.Dispatch
`Pages/scripts/popup.js`	Scripting	Dispatch switched to the shared own-property-guarded Message.Dispatch
`Pages/scripts/search.js`	Scripting	Search character folding (folds stop words, forwards folding spec to baggage highlighter); IndexedDB search-chunk caching with per-parcel cache keys and write-through on network load; absent/corrupt chunk tolerance keeps scope maps aligned and the spinner alive; breadcrumb chunks drained on idle instead of re-walking all anchors; shell-only (zero-parcel) builds still complete the query
`Pages/scripts/search-client.js`	Scripting	Client search tokenizer folds query words to canonical form (matching the folded build-time index) and expands foldable characters into regex character classes for highlighting
`Transforms/baggage-search-index.xsl`	Transform	Locale-driven character folding configured into the C# baggage indexer; indexed words, synonyms, and stop words folded to canonical form so baggage indexing matches the content index and client tokenizer
`Transforms/breadcrumbs.xsl`	Transform	A breadcrumb entry resolving to the page being generated is emitted as plain text instead of a self-referential link
`Transforms/compose.xsl`	Transform	New file — federated-composition renderer: rebuilds the composed parcels manifest from a merge-settings spec plus harvested per-parcel manifest leaves, so a composition job can splice parcels into a deployed shell's index.html without rebuilding any parcel
`Transforms/connect.fti`	Configuration	New Generate Groups setting (connect-groups-generate; false builds a content-free shell); AI Assistant settings enabled plus knowledge-base-per-parcel and hide-when-file-local; new menu-default-tab setting (assistant/toc/index); new accessibility group with accessibility-optimized-reader-mode setting
`Transforms/connect.xsl`	Transform	Per-parcel search/landmark cache hashes emitted as data attributes on parcel manifest anchors (rebuilds only evict changed parcels' caches); shell-only mode emits an empty parcels manifest; MergeSettings fallback synthesizes one merge group per top-level group; optimized-reader page condition and new script replacements (default tab, hide-when-file-local, optimized reader)
`Transforms/content.xsl`	Transform	Custom-marked footnotes supported (mark rendered instead of a number, no number consumed, link targets the note paragraph); `ww` prefix removed from generated IDs, aria-controls, and link anchors; nested table/frame note scoping fixed; image title via shared Images-Title template; character-style tag can come from the document style catalog; runtime-link regex extended to match #/ anchors
`Transforms/descriptor.xsl`	Transform	New file — emits a durable per-parcel deploy descriptor into each group's output (composition metadata, url_maps slice, and a byte-identical parcels-manifest leaf) plus a shell descriptor; the bootstrap contract for federated composition
`Transforms/index.xsl`	Transform	Index generation gated on Generate Groups, so a shell-only target emits no per-group index
`Transforms/knowledge-base-content.xsl`	Transform	Knowledge-base anchors computed via Landmarks-ComputeLandmarkID (honors landmark-id-format); nested-table note scoping fix; image title via shared Images-Title template
`Transforms/knowledge-base-pages.xsl`	Transform	Knowledge Base zip renamed to knowledge-(project)-(generation-hash).zip; new per-parcel mode emits one knowledge zip per top-level group with its own groupID; guards against zero knowledge pages on shell builds
`Transforms/landmarks-json.xsl`	Transform	New file — format-local landmarks JSON driver whose per-group loop is gated on Generate Groups, so shell-only targets emit no landmark chunks; reuses shared landmarks-core.xsl
`Transforms/not-found.xsl`	Transform	Companion-PDF linking suppressed when Generate Groups is disabled
`Transforms/pages.fti`	Configuration	New landmark-id-format paragraph-style option (hashed-16 default, hashed-8, source-id); new report-links-runtime-anchor report setting (default ignore) declaring runtime hash anchors as browser-resolved
`Transforms/pages.xsl`	Transform	Page generation and companion-PDF link skipped for shell-only builds; page-landmark-id computed via Landmarks-ComputeLandmarkID; last-modified date can be overridden by a `date` marker; optimized-reader page condition; `ww` prefix dropped from dropdown IDs; obsolete highlight-require-whitespace replacement removed
`Transforms/parcel.xsl`	Transform	Parcel generation gated on Generate Groups; parcel TOC data now emitted whenever the splash page is in use (feeds the Contents groups grid); `ww` prefix removed from generated anchors
`Transforms/project-copy.xsl`	Transform	Adds Page/Popup page-template inputs to the action checksum and inventories group-level template chrome for zero-document (federated shell) builds
`Transforms/sass.xsl`	Transform	Adds Pages/sass/custom.scss to the SCSS inventory and action checksum (user override hook); passes an assistant_generate Sass variable from ai-assistant-generate
`Transforms/search.xsl`	Transform	Emits the locale's character-folding pairs into search.js so the client tokenizer folds like the index; optimized-reader page condition; obsolete highlight-require-whitespace replacement removed
`Transforms/search-index.xsl`	Transform	Character folding configured into the C# search indexer (words, synonyms, stop words); per-group index and word-pair generation gated on Generate Groups
`Transforms/sitemap.xsl`	Transform	Group enumeration gated on Generate Groups, suppressing per-group sitemaps and stub-group references in shell-only builds
`Transforms/splash.xsl`	Transform	New groups-grid-label replacement from the GroupsGridLabel locale string; optimized-reader page condition; companion-PDF linking gated on Generate Groups
`Transforms/styles.xsl`	Transform	Per-group document CSS generation gated on Generate Groups; character-style CSS also emits span.(class) selectors when the style's tag is not span

Markdown++ Output

File	Category	Summary
`Transforms/content.xsl`	Transform	Nested-table note scoping fix; image title attribute resolved through the shared Images-Title template (tooltip vs. alt-text separation), including the Markdown image-link path

PDF

File	Category	Summary
`Transforms/compile.xsl`	Transform	Upgrades Apache FOP 2.8 to 2.11 (wildcard CLASSPATH); a failed FO-to-PDF conversion (non-zero exit or missing PDF) is now reported as a generation error instead of silently succeeding; FOP console output partitioned so INFO noise logs as progress and only warning/error lines log as warnings
`Transforms/content.xsl`	Transform	Preformatted paragraphs may break across pages (taller-than-page code blocks no longer clipped); nested table/frame note scoping fix; raster images with explicit width/height/content-width/content-height dimensions are scaled by the FO engine at render time, preserving full resolution instead of pixel resampling

Dynamic HTML

File	Category	Summary
`Transforms/content.xsl`	Transform	Custom-marked footnotes supported (mark rendered instead of a number, no number consumed); nested table/frame note scoping fix; character-style tag can come from the document style catalog; image title attribute via shared Images-Title template
`Transforms/styles.xsl`	Transform	Character-style CSS also emits span.(class) selectors when the style's tag is not span, so styling applies to both the semantic tag and span fallbacks

Markdown++

File	Category	Summary
`helper/markdown/markdown/frontmatter.py`	Adapter Parsing	New file — converts YAML front matter at the top of a document into a markers:{} directive attached to the first content block Flat key-value pairs, quoted scalars, and flow arrays; keywords/description keys canonicalized to the stock Keywords/Description marker names
`helper/markdown/markdown/includes.py`	Adapter Parsing	Front matter converted once per file before condition and include processing Link targets with any URI scheme (mailto:, tel:, ftp:, ...) are no longer rebased against the document directory as file paths
`helper/markdown/markdown/parser.py`	Adapter Parsing Imaging	Custom aliases and auto-generated heading slugs resolved as separate namespaces with deterministic collision suffixes (custom alias wins the bare identifier; duplicate custom aliases report MDPP008); element IDs derive from the primary alias so anchors and landmarks stay stable; NFC normalization keeps accented identifiers consistent Multiline table cells: unstyled top-level paragraphs take the cell's style; whitespace-only separator rows no longer emit empty structure-breaking rows; code spans honor CommonMark delimiter-run and space-padding rules; fragment-only links (including Reverb runtime hashes) keep an empty URL for same-document resolution Reference-style image alt text uses the reference label; the tooltip (title) is declared explicitly on every image so formats can distinguish "no tooltip written" from "no tooltip field"; tables emit one TableColumn definition per column (width "auto") so formats can attach column widths
`helper/markdown/markdown/patterns.py`	Parsing Adapter	Inline code accepts multi-backtick delimiter runs; intra-word underscores no longer open or close emphasis (CommonMark flanking rules) so snake_case passes through as text Condition names may contain hyphens; new URI-scheme expression (excludes single-letter Windows drive references); new block-tag scan and fenced-code expressions supporting the custom-alias pre-scan
`helper/markdown/markdown/styles.py`	Adapter	Default style catalog now declares semantic HTML tags (h1-h6, p, blockquote, pre, strong, em, code, del) with zeroed margins so rendered geometry is tag-independent; title style split into title 1 / title 2 levels; a style name used by more than one element kind drops its tag to avoid invalid nesting
`helper/markdown/markdown/variables.py`	Parsing	Escaped variable references (backslash before $name;) emit the reference as literal text — never substituted and never added to the project's variable list; code fences, code blocks, and code spans remain untouched

Adobe FrameMaker

`xml/scripts/dita/ant/webworks-4.4.xml`	Adapter	New file — Ant build script for DITA-OT 4.4
`xml/scripts/dita/ant/xsl/webworks-pdf-prep.xsl`	Transform	Synthesizes a minimal DITA map for bare-topic inputs (topics added to a project without a ditamap), so DITA-OT topicmerge no longer produces empty merge output and the pdf2 plug-in no longer aborts
`xml/scripts/dita/xsl/batch-files.xsl`	Adapter	Adds DITA-OT 4.4 support (new default) with a Java 17-or-later environment check and its own batch-file template using FOP 2.11
`xml/scripts/dita/xsl/generate-xml.xsl`	Transform	Reads the new dita-use-source-ids adapter setting into the generate pipeline
`xml/scripts/dita/xsl/generate-xml/util.xsl`	Transform	Generate-ID uses the element's source @id when dita-use-source-ids is enabled, caching per node and deduping duplicate IDs with _2/_3 suffixes and a warning; new Compute-Satellite-ID keeps satellite element IDs collision-proof (colon-suffixed names cannot collide with NCName source IDs)
`xml/scripts/dita/xsl/generate-xml/paragraph.xsl`	Transform	Topic and section titles inherit their parent's source @id under dita-use-source-ids; markopen/markclose paragraph IDs built via Compute-Satellite-ID
`xml/scripts/dita/xsl/generate-xml/content.xsl`	Transform	Markopen/markclose paragraph IDs built via Compute-Satellite-ID
`xml/scripts/dita/xsl/generate-xml/character.xsl`	Transform	Markopen/markclose, trademark, and copyright TextRun IDs built via Compute-Satellite-ID
