# May Update 2026 Check out what we've been doing at Terra over the month of May 2026! ### Backend 💾 #### Features * New integration: **Mira** is out, with full hormone data support 🩸 * New integration: **Trailforks** is out * New integration: **Rouvy** webhooks are out * New integration: **Omron** webhooks are out * **Fitbit v2 API** integration is live * **Bring-your-own-app OAuth** pathway available for Strava, Oura, and WHOOP — connect your own OAuth app to Terra * New **AI Health Context** endpoint — query an LLM-grounded summary of a user's recent health data through the API * New **Hormone** scope available * **Raw FIT files** are now captured and stored from provider integrations * TrainingPeaks **strength workouts** are now included in the planned-workout response * Planned workouts on **Apple** are now supported * MacrosFirst now surfaces **weight** data * New webhook header `X-Terra-Ordering-Timestamp` exposes the emit-time of each event for ordering downstream * Daily Stress score (`SS_DAILY_STRESS`) re-enabled with a simpler training formula * Apple Health activity & lap average heart rate is now time-weighted for accuracy #### Bug fixes * Fixed a bug where Garmin swim summary aggregates were not mapped to lap and activity fields * Fixed a bug where Garmin `TRAIL_RUNNING` and `GRAVEL_CYCLING` activity types were not mapped correctly * Fixed a bug where Garmin planned-workout API errors surfaced as `500`s instead of `424`s with normalised messages * Fixed a bug where Garmin daily step / distance / active-calorie totals were not derived from epoch samples * Fixed a bug where Garmin absolute speed bounds were not derived from threshold/percentage targets for SPEED/PACE workouts * Fixed a bug where Fitbit re-delivery could overwrite a better GPS track * Fixed a bug where Fitbit daily steps and distance were not derived from intraday samples * Fixed a bug where Fitbit calories / activity-level samples used the wrong anchor time * Fixed a bug where Fitbit v2 was emitting passively-measured `SpO2` sentinel values (`percentage=50`) * Fixed a bug where Apple HealthKit body-fat values were sent as a fraction rather than a percent * Fixed a bug where Apple SDNN samples were not being set * Fixed a bug where Apple steps did not fall back to summing intraday samples * Fixed a bug where Apple all-zero daily records were not dropped for completed past days * Fixed a bug where Oura activity type mappings were incorrect * Fixed a bug where Zepp elevation summary fields and summary polyline were missing * Fixed a bug where Zepp GPS coordinates were scaled incorrectly * Fixed a bug where Zepp workout step count was not surfaced from the sports endpoint * Fixed a bug where Wahoo elevation summary fields were missing from FIT sessions * Fixed a bug where Huawei out-of-range pace targets caused hard errors instead of structured warnings, with pace values now clamped to the allowed range * Fixed a bug where COROS planned workouts required leaf intensity on repeat steps (now defaults to active) * Fixed a bug where Clue's current cycle was not fetched correctly * Fixed a bug where MyFitnessPal per-meal calories were `0` when MFP returned `value=null` (now correctly `nil`) * Fixed a bug where MacrosFirst food-level meals used the wrong parent meal name for the `MealType` mapping * Fixed a bug where the Apple and Fitbit responses drifted from our schema for several daily fields * Fixed a bug where `GET /v2/daily` returned future-dated daily records * Fixed a bug where workout / planned-workout IDs in `v2` were returned as numbers (now JSON strings for precision) * Fixed a bug where provider `429` rate-limits were surfaced as `424`s * Fixed several **score formula** transcription bugs — Activity Efficiency, `SS_DAILY_STRESS_V2`, `SS_RESPIRATORY_V2`, and Daily Strain * Fixed a bug where `SS_RESILIENCE` and `SS_READINESS` capped at 80 instead of running to 100 #### Changes * Webhook delivery now spools to disk and parallelises per-entry uploads for S3 destinations * Non-webhook destinations (GCS, SQL, Firestore, Supabase, Azure Blob, MongoDB) migrated to a streaming pipeline for lower memory and latency * Webhook dispatcher hardened with a per-destination safety-valve circuit breaker *** ### SDK 📱 #### [TerraiOS](ref:reference-ios-sdk) — `1.7.3` * Handle request failures correctly so an individual sample-type failure no longer breaks a whole sync * Background delivery now bounds observer-fire fan-out and adds a per-push cap (1.7.2) * Snowflake IDs are now decoded as `String` to avoid JavaScript number-precision loss * HealthStore now averages across all daily buckets, and `predicateOptions` was renamed to `options` * Sleep wrist-temperature query predicate relaxed so more devices report a value * Server-driven initial backfill on `initConnection` for Apple Health *** ### Frontend 📺 #### Landing Page ([tryterra.co](https://tryterra.co)) * New self-serve **DPA** page and ToS reference for enterprise customers () * Research articles now ship with a dedicated **Methodology** section and an **auto-generated FAQ** powered by Claude * Podcast page redesigned around per-episode article-style layouts, powered by the official **Spotify Web API** * New **planned workout pricing** on the pricing page * "**Become an Integration**" CTA added across homepage and footer * Toast notification banner connected to our Instatus status page so customers see incidents in real time * DPA + ToS last-updated date refreshed to May 1st, 2026 #### Dashboard ([dashboard.tryterra.co](https://dashboard.tryterra.co)) * **Scores V6** redesigned page is live — new modules for Daily Strain, the Activity quad (Strain / RCRS / TRIMP / Efficiency), Immunity, Resilience, Readiness, Sleep V2, Respiratory V2, and Daily Stress V2 * New **Score Sandbox** with a Sleep score playground — tweak inputs and see how scores change live * **Provider health** page is out — see provider status / outages at a glance * New **Hormone** scope available in the scopes UI * **Synthetic data fetch** — pull realistic synthetic samples without needing a real connection * Click-wrap updated to include **DPA + SCC** acceptance, with version-based terms tracking * Immunity now renders on its native 0–5 scale, and unbounded scores (RCRS, TRIMP) render as scale-aware histograms *** ### Blood Biomarkers 🩸 * Backfilled **1,506 LOINC codes** for the biomarker reference set * New public `biomarkers.json` generator so customers can sync the reference set * Lab-reports model default upgraded to `claude-opus-4-7` for higher-quality extraction --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in
