Include previous/next page URLs, current page and total page counts, and user reactions in the Snap Changelog RSS feed (snap_changelogs/show.rss.builder). Enhances the RSS with navigation metadata and reaction data so feed consumers can paginate reliably and surface engagement.

Adds a new boot option that shows the boot UI only when a user drags an image onto the drop area. Implemented in app/javascript/bundles/changelog/media-upload-receiver.js, introducing drag-detect logic (useDragDetect, onDragEnter/Leave/Drop/Over) and a boot-preference update flow under MediaUploadReceiver. This upcoming default behavior cleans up the initial UI and ties boot visibility to the drag action, with no bug fixes.

Adds a responsive, high-contrast long-term sparkline (app/javascript/bundles/cab-viewer/historic-sparkline.js) with date labels, resize handling and styled plotting to the Commit Activity Browser. Fixes Elite history fallback by aligning Elite history to the all-time window and falling back to the entity subscription when a resource subscription is missing; tests and factories updated. Improves long-term activity visibility and restores correct Elite history data.

Adds a v1 HistoricSparkline component and styles to render a compact commit-activity sparkline above the Commit Activity Browser. Changes touch historic-sparkline.js/.scss and include styling and render tweaks in recent-branches-prs-viewer.js/.scss, wiring hover/click behavior and cleanup. Deployed to production 2025-09-19 — provides an at-a-glance view of historic commit activity.

Add a faculty-level toggle to disable repository and team aggregation and expose the active aggregation mode. Fix release-driven chart stats by using release-specific metric segments, aligning release timestamps, and deduplicating deploy_committer entries (tests updated). Refactor RebuildResourceTeamStatConcern so rebuild_commit/rebuild_for_release accept an injectable logger and forward it into collect_team_stats/recalculate — improving chart accuracy, per‑faculty control, and rebuild logging.

Ensure users who request a team they cannot access are redirected to a team they can access by updating the ApplicationResourceConcern (derive_team_and_member). Also add a resource_team_stats association to resources, add CommitFactory.create(tag_name:), and a WIP integration test (test/integration/resource_team_stats_test.rb) to validate aggregate changes. Improves access handling, UX, and team-level stats testability.

Add a direct 'squash commit' link to the PR "Commits" tab (app/views/pull_requests/commit_list.html.haml) per Codrin's suggestion. Small view-only change that surfaces a link for each commit to access squash commit details quickly. Deployed to production 2025-09-19, improving navigation and workflow efficiency.

Adds denormalized team member counts and surfaces them in the team switcher. Introduces a TeamExtra migration/model, adds denormalize_team_stats and related methods to TeamMember, and updates Team/TeamExtra so the UI can display per-team member totals. Deployed to production 2025-09-19; users can now see member counts for faster, clearer team selection.

Commit title generation (app/models/commit.rb) now enforces a sentence cutoff before TITLE_SENTENCE_CUTOFF_LENGTH (default 60) and moves any remaining characters into the commit description. Added a committer_changelog test to validate the behavior. Impact: keeps changelog titles concise and sentence-complete while preserving overflow text in descriptions and preventing regressions.

Moved magnitude-selector logic from tracker_project_issue.rb into ChangelogProps and implemented derive_magnitude_em with assorted heuristics (vendor/gems/chart_glimpses/.../changelog_props.rb). Minor CommitterChangelog adjustments to consume the new selector. Replaces Diff Delta as the magnitude source and supplies richer magnitude/category metadata for AI-driven blog generation.

Introduce a suppress_aggregation flag in the reporting API and wire it through presenter/concern logic so charts can opt out of repo- or team-based aggregation. Changes touch StatScopeAndGrouperConcern, HistoricRepoCommitterStat, API definitions and tests. Exposed via Chart Settings on site, this lets faculty request unaggregated chart data for more precise reporting.

Implements drag-based navigation for the CAB date picker by adding a grabber-driven drag flow in CabDatesFrame (renderDate::useGrabber, handleDragStart/Move/End) and corresponding styling updates in cab-dates-frame.scss. Files affected: app/javascript/bundles/cab-viewer/cab-dates-frame.js and cab-dates-frame.scss. The change makes the CAB dates area draggable, improving discoverability and usability of the scroll affordance for end users.

Restore the hover explanation for commit activity bubbles in the CAB and update icon-priority logic so commits pending review take precedence over dependency/migration changes, then changelog publish, then received-comment. Changes touch bubble-hover-tooltip.js (tooltip text/logic) and commit-activity-bubbles-svg.scss (appearance/order). Deployed to production; improves clarity and prevents misleading status icons.

Integrated CabActivityCache into the Commit Activity Browser: added cache lookup and bubble_bound JSON wiring (cab_activity_cache.rb, bubble_bound_calculator.rb) and accompanying tests. Cache reuses recent activity per time zone so large teams that access CAB from the same zone more than once daily see ~10x faster loads. Deployed to production; next up: pre-warming auto-cache for frequent users.

Adds a magnifying-glass icon to mark Diff Delta items that require review, with the icon size scaled to the amount of unapproved changes. Implemented in the cab-viewer UI (app/javascript/bundles/cab-viewer/cab-defines.js and cab-viewer/commit-activity-bubbles-svg.scss) and supported by the BubblePresenter logic to compute circle radii. Improves visibility of pending reviews and helps reviewers focus on the most impactful diffs.

This work introduces a real distinction between CAB short and long titles, incorporating issue identifiers into short titles when available, and refines the derive_short_title logic for accuracy. It also fixes a bug in createElement attribute assignment in web-util.js. Additional improvements touch the JavaScript utility library, the commit_activity_browser gem (bubble_presenter_concern.rb), and the gc_util gem (api_utility.rb). Layout updates in _head_tag.html.haml and _footer.html.haml; sub...

Add a real short-vs-long title distinction for the Commit Activity Browser: implemented derive_short_title in BubblePresenterConcern to produce concise titles (including issue identifiers when present), updated commit-activity-browser-configurator to surface title options, and a minor cab-tick.js text-position tweak. Result: CAB displays consistent, scan-friendly titles with issue IDs in compact views.
