v1.4.0

[1.4.0] — 2026-08-10

Schema: 20.

Added

• File version history (pdfs-fuse/src/revisions.rs + a GTK versions dialog): list a
  file's revisions, restore one, delete one, or write an old one out to a local path. A
  restore re-points the file server-side, so no content crosses the wire and nothing enters
  the drain queue; the daemon drops its cached content and repopulates on the next read.
• Persistent SDK entity cache (pdfs-core/src/sdkcache.rs): the SDK's decrypted node
  metadata now survives a daemon restart instead of re-walking the tree. It lives in its own
  sdk_cache.db, deliberately off the daemon's hot cache.db mutex, holds no key material,
  needs no migrations, and is cleared on logout.
• Per-node outcomes for batch operations (pdfs-core/src/batch.rs): trash/restore/
  delete/move report one result per node, so a node the server rejects no longer fails
  the whole batch.
• Photo viewer page in the GUI and richer photo metadata in the details pane.

Changed

• SDK telemetry routed into tracing, so its transfer/block-storage/request spans land in
  the daemon log instead of a no-op sink.
• A file that fits in one block uploads as a single atomic request rather than the
  draft/block/commit sequence.
