+## [0.12.0] — 2026-02-25
+
+### Added
+- **File handling and vision support.** Upload images, PDFs, and documents
+  into chat via 📎 button, drag-and-drop, or paste. Multimodal message
+  assembly injects base64 images for vision-capable models and extracted
+  text for documents. Staged attachment strip shows upload progress and
+  extraction status. Auth-aware blob rendering with Bearer tokens. Image
+  lightbox viewer. Vision capability hints on image attachments.
+- **Storage backend abstraction.** `ObjectStore` interface with two
+  implementations: PVC (local filesystem) for single-node/dev and S3
+  (minio-go) for multi-node production. S3 backend works with any
+  S3-compatible API: MinIO, Ceph RGW, AWS S3. Auto-detection when
+  `STORAGE_BACKEND` is not set (tries PVC, disables if not writable).
+  Both backends share identical semantics — all handlers, attachment
+  CRUD, multimodal assembly, and orphan cleanup work regardless of
+  backend.
+- **S3 configuration.** `S3_ENDPOINT`, `S3_BUCKET`, `S3_ACCESS_KEY`,
+  `S3_SECRET_KEY`, `S3_REGION`, `S3_PREFIX`, `S3_FORCE_PATH_STYLE` env
+  vars. Endpoint auto-detects SSL from scheme. Path-style URLs default
+  on (required for MinIO/Ceph). Optional key prefix for shared buckets.
+  CI pipeline syncs S3 secrets to K8s when `STORAGE_BACKEND=s3`.
+- **Text extraction pipeline.** PDF, DOCX, XLSX, PPTX, ODT, RTF text
+  extraction via filesystem-based queue. Inline and sidecar modes.
+  Crash recovery for items stuck in processing state.
+- **Admin storage panel.** Backend health, file count, total size,
+  orphan detection and cleanup. Shows PVC path or S3 endpoint/bucket
+  depending on active backend. Extraction queue status.
+- **Vault CLI commands.** `switchboard vault rekey` re-encrypts all
+  provider API keys when rotating the encryption key.
+  `switchboard vault status` shows encryption health. Admin UI
+  encryption status indicator in Settings tab.
+- **Per-chat model persistence.** Server-side `channels.settings`
+  JSONB field stores `last_selector_id`. Roams across devices with
+  localStorage write-through cache as fallback.
