v0.7.2

Fixed

• Tilt polling no longer duplicates readings across multiple active batches when the same hydrometer is linked to more than one — writes to the first (oldest) batch only and logs a warning
• Dashboard entry count now includes hydrometer_readings rows, so Tilt-only batches display a correct count instead of zero
• CSV import now detects gravity stratification in the first 24h of readings and sets the batch OG to the peak gravity rather than the first reading; pre-peak readings are imported with isExcluded = true, excludeReason = "stratification"
• CSV import no longer auto-links the historical import to a currently registered Tilt of the same color — hydrometer selection in import mode is now optional and always user-initiated

Changed

• hydrometer_readings.hydrometer_id is now nullable; readings imported without a device link are fully supported

v0.7.1

Fixed

• Batch deletion now hard-deletes with cascade instead of archiving; batch settings includes a danger-zone "Delete batch" action gated behind a name-confirmation dialog
• Tilt polling status accurately reflects running state across Next.js module contexts by persisting tilt.lastPollTime to the DB and deriving running from recency rather than an in-memory flag
• Adding the first Tilt hydrometer now auto-enables polling without requiring a separate settings toggle
• Protocol tab correctly displays "Gravity stable for 24h" instead of "3 readings" when stableDurationHours is set; seed templates and default criteria builder updated to include stableDurationHours: 24

v0.7.0

Added

• Standard protocol mode for batch wizard: opinionated wine phase defaults (Primary, Secondary/MLF, Clearing, Aging, Bottling, Bottle Aging) with red/white variants
• Phase reordering: drag-and-drop and up/down arrows to reorder all phases in the wizard
• Contextual phase suggestions: nitrogen-demand-aware nutrient timing, punch-down for reds, fining agents, bottling additions — shown as opt-in chips per phase
• Custom phase support: add user-defined phases with configurable completion criteria, interspersed with standard phases
• Time-window gravity stability: stableDurationHours criteria checks all readings within a window (e.g. 24h) rather than just consecutive readings
• Phase suggestion engine (phase-suggestions.ts) with yeast nitrogen demand lookup from reference data
• Default wine phase definitions (default-phases.ts) for red and white wine with temperature ranges and completion criteria
• Hydrometer reading outlier detection with IQR-based anomaly flagging
• Reading cleanup UI for reviewing and removing outlier readings
• Additives form overhaul: searchable dropdown with common wine/beer additions grouped by category
• Wine color theming utilities
• Reference data: expanded yeast strain database with nitrogen demand ratings

Changed

• Batch wizard Protocol step redesigned: Standard mode shows all phases in a single reorderable list with inline on/off toggles for optional phases
• Phase engine evaluates stableDurationHours for gravity_stable criteria (backward compatible — falls back to consecutive readings when unset)
• Phase indicator supports new phase types and displays phase count accurately
• Fermentation chart styling refinements
• Batch detail page layout improvements
• Status badge component updates
• Searchable combobox ARIA compliance (added aria-controls)

v0.6.0

Added

• Backfill unlinked hydrometer readings: Tilt readings stored with batch_id = NULL when no active batch exists, claimable during batch creation
• Unlinked readings API: GET/POST /api/v1/hydrometers/[id]/unlinked-readings for querying and claiming orphaned readings
• Batch wizard backfill prompt: shows count, SG range, and "include these readings" checkbox when creating a batch with a Tilt that has unlinked data
• New user onboarding: /welcome page with timezone auto-detection, unit preferences (temp, volume, gravity), and Tilt prompt
• User preference settings: user.timezone, user.tempUnit, user.volumeUnit, user.gravityUnit, onboarding.complete
• Searchable combobox component for style and yeast selection in batch wizard
• Reference data: built-in wine/beer style list and common yeast strains with temp ranges
• Standalone Tilt CSV parser (parse-tilt-csv.ts) extracted from import module

Changed

• hydrometer_readings.batch_id is now nullable — readings can exist without a batch
• Tilt adapter stores readings even when no batch is linked (previously dropped them)
• Dashboard redirects fresh installs (no batches + no onboarding flag) to /welcome
• Daily recap generation uses configured timezone instead of UTC for determining "today"
• Batch wizard step 1 uses searchable dropdowns for style and yeast fields

Fixed

• Seed data yeast strain naming consistency (RC212 → RC-212)

v0.5.0

Added

• Batch Settings tab with manual OG field (auto-saves on blur/enter)
• Hydrometer live status API: GET /api/v1/hydrometers now returns status (live/waiting/unknown), lastGravity, lastTemperature, minutesSinceLastReading derived from lastSeenAt vs poll interval
• getLatestReadingByHydrometer() query for fetching most recent reading by hydrometer ID
• Live network scan in batch wizard: selecting a hydrometer triggers a TiltPi scan to verify it's broadcasting, independent of polling history
• "Scan for Tilts" button in wizard Connect step wired to /api/v1/hydrometers/scan
• HydrometerWithStatus and HydrometerStatus types

Changed

• Removed starting gravity (OG) from batch wizard step 1 — OG is now set via batch Settings tab, hydrometer auto-read (future), or CSV import (future)
• Wizard Connect step redesigned: shows hydrometer status indicators, live reading from scan, contextual messages for waiting/unknown states
• Hydrometer status model uses honest labels: "live" (receiving data), "waiting" (registered, awaiting data), "unknown" (never reported) instead of misleading "offline"

Fixed

• Dashboard batch cards rendering stray "0" from JSX short-circuit evaluation of overdueActionCount and unresolvedAlertCount

v0.4.1

Added

• Smart timeline consolidation: Tilt hydrometer readings now appear on the timeline as individual entries (last 4) and hourly summaries (older), computed at read-time from hydrometer_readings
• HourlySummaryEntry component for rendering consolidated hourly reading buckets
• timeline-consolidation.ts module for timezone-independent reading consolidation
• hourly_summary timeline entry type with HourlySummaryData interface

Fixed

• Dashboard cards for Tilt-only batches now show gravity and temperature (previously blank because only timeline_entries was checked, not hydrometer_readings)
• Timeline consolidation no longer depends on UTC "today" — uses unrecapped reading dates instead, fixing timezone-related empty timeline bug

v0.4.0

Added

• Hydrometer device management: register, edit calibration, toggle active, scan for Tilts on the network
• Hydrometer CRUD API (/api/v1/hydrometers) with scan endpoint for TiltPi BLE discovery

• Alert detection on reading ingest: stuck fermentation, temperature drift, gravity anomaly

Changed

• Tilt polling config moved from environment variables to database-backed Settings UI
• Batch creation accepts optional hydrometerId to link a hydrometer
• Timeline source enum updated to manual | hydrometer-auto | hydrometer-confirmed | system | api
• Scan route reads TiltPi URL from DB settings instead of env vars

Added

• Protocol templates system with 3 built-in templates (Kit Wine Red, Kit Wine White, Simple Beer Ale)
• Template CRUD API (/api/v1/templates) with built-in deletion protection
• Batch phases: ordered phase sequences with status tracking (pending/active/completed/skipped)
• Phase engine evaluating 5 completion criteria types: gravity_stable, duration, action_count, manual, compound
• Phase actions with scheduling (one-time and recurring) and overdue tracking
• Phase management API: advance-phase, skip-phase, phase-status endpoints
