 ## [Unreleased]
 
+## [0.16.0] — 2026-07-18
+
+### Added
+- **Show / Add tabs on the patient record dialog.** Editing a record now opens on a read-only
+  "Show" view (the existing `PatientDetail`), with an "Add" tab for the editable form and its Add
+  buttons. Saving from the Add tab still offers the existing "send to the patient's wallet" step
+  when the patient is wallet-linked (`frontend/components/chat/patient-form-dialog.tsx`).
+- **Barcode scanning in the pharmacy.** The inventory Add-item dialog can now scan a medication
+  barcode with the camera (`@zxing/browser`, native `BarcodeDetector` where available) into a new
+  Barcode/NDC field, auto-filling expiry (AI 17) and lot (AI 10) from a GS1 DataMatrix. Adds a
+  nullable `inventory.barcode` column (migration `0036`).
+- **Scan a patient's wallet code when importing.** "Import from a patient app" gains a Scan button
+  that reads the QR or 2D barcode shown in the patient's wallet app and fills the wallet number
+  (`frontend/components/patients/import-from-wallet-dialog.tsx`).
+
+### Changed
+- **Settings "separated panels" now match COSS exactly.** The opt-in `separated` settings frames
+  render a real COSS Frame — a muted tray holding distinct bordered panels spaced apart — instead
+  of a `gap-4` bolted onto the panel-fusing `CardFrame`. New `frontend/components/ui/frame.tsx`.
+
+## [0.15.1] — 2026-07-17
+
+### Fixed
+- **Settings frames with more than one panel now breathe.** When a settings section stacked
+  several cards — the AI availability toggles and the patient/account notification lists — the
+  panels sat flush against each other with no gap, reading as one joined block. Those frames now
+  use the COSS "separated panels" spacing (a 1rem gap that keeps each card's rounded corners),
+  while intentional joined lists (care team, records) stay flush. Opt-in via a new `separated`
+  prop on `SettingsFrame`/`SettingsSection` (`frontend/components/settings/settings-parts.tsx`).
+
+## [0.15.0] — 2026-07-15
+
+### Fixed
+- **Prescriptions pushed to a wallet now actually arrive.** `createPrescription` writes to the
+  `prescriptions` table, but the sealed bundle only carried `patient.medications`, which comes from
+  the separate `patient_medications` table and never grows when a prescription is written. The
+  patient approved a bundle identical to what they already had, so nothing appeared in the app's
+  Prescriptions section — the "New prescription: X" line in `changes` is display text, not data.
+  The bundle now ships `prescriptions` alongside the appointments and invoices that were already
+  handled this way, keeping prescriber/status/dates (`backend/src/services/wallet-updates.ts`).
+- **No more bogus "this clinic's key changed" warnings.** Update events now carry a stable
+  `clinicId`. Wallets pinned a clinic's signing key against its display *name*, which is mutable
+  and falls back to the literal "A clinic" for unnamed orgs — so two unnamed clinics collided on
+  one pin and the second always warned.
+- **Silent drops on the wallet-push path are now logged.** `sendToWallet` no-ops when an org has no
+  live relay hub, and `applyUpdateResponse` returned `null` without a word when a response arrived
+  unsigned or already resolved. From the clinic side both looked exactly like a patient who never
+  tapped Approve.
+- **Windows checkouts no longer break the backend image.** The repo had no `.gitattributes`, so Git
+  for Windows' default `core.autocrlf=true` rewrote `docker-entrypoint.sh` to CRLF; the container
+  then died with `exec /usr/local/bin/docker-entrypoint.sh: no such file or directory`. Line
+  endings are pinned, and the image strips CR before `chmod` so existing checkouts are fixed too.
+- **Settings frames use the COSS default padding.** `CardFramePanel` (added in 0.14.0) isn't part of
+  the COSS registry: its `p-5` inset content twice over, and wrapping the body made every card a
+  grandchild of `CardFrame`, so the frame's direct-child selectors never applied and each card drew
+  its own border — a box inside a box. Body padding now sits on the card, where COSS puts it.
+- **99 lint errors cleared.** `npm run lint` had been failing (the build hides it via
+  `eslint.ignoreDuringBuilds`). Vendored `components/charts` and `components/ai-elements` are now
+  ignored; the 31 in our own code are fixed. Two were real bugs: the employee dialog could keep a
+  typed password when switching to another member, and the wallet-sync hook could carry a patient's
+  `linked` state to a newly-selected patient, briefly offering to push a record to someone else's
+  wallet.
+
+### Changed
+- The clinic→wallet update event carries `clinicId`, and the sealed bundle carries `prescriptions`.
+  Both are additive; older wallets ignore them. See the
+  [signing API docs](https://docs.temetro.com/docs/api/signing#clinic--wallet-record-updates).
+
