 - Version hash now injected via build arg (`NEXT_PUBLIC_VERSION`) and shown in footer; build scripts updated.
 - In-cluster Varnish cache added in Deployment to cache `/api/images/*` and static assets.
 - Added `generate_images.py` and committed sample image assets for reseeding/rebuilds.
+- Price hint now stored in euros (schema field `priceHintPerNightEuros`); Prisma migration added to convert from cents, seeds and API/UI updated, and build now runs `prisma generate` automatically.
+- Listing creation amenities UI improved with toggle cards and EV button group.
+- Mermaid docs fixed: all sequence diagrams declare their participants and avoid “->” inside message text; the listing creation diagram message was rewritten to prevent parse errors. Use mermaid.live or browser console to debug future syntax issues (errors flag the offending line/column).
 
 To resume:
 1) If desired, render diagrams locally: PlantUML in `docs/plantuml`, draw.io in `docs/drawio`.
