Release Notes

Changes since v0.8.5. Breaking changes

  • lore-client: logging CLI arguments are now strictly mutually exclusive; a command line passing conflicting logging flags is rejected instead of silently accepted
  • Auth login/info now return NotSupported (code 18) when the server has no auth endpoint configured, and surface NotAuthenticated / Disconnected instead of a generic internal error (code -1); scripts branching on these exit/FFI codes must be updated
  • Presigned URL vending (POST /v1/repository/{id}/content/{address}/presign) is now restricted to service accounts; normal user tokens can no longer mint presigned URLs Features
  • lore-server: forward BranchList and RepositoryCreate to a remote Lore server when configured (extending the existing BranchCreate/BranchDelete/BranchGet forwarding)
  • lore: add a batch node-add verb (lore_revision_tree_add) to the low-level revision API, landing a whole subtree atomically
  • lore: run the service process (lore service run) on Linux and macOS, not just Windows
  • lore: validate that all strings passed to the C API are valid UTF-8, rejecting invalid input up front with a named field
  • lore-server: support file:// JWKS endpoints in the JWK service
  • lore-revision: optional durable_delay on the composite store so read replicas can answer before the durable tier is queried
  • lore-storage: self-heal corrupt (torn-write / zero-filled) mutable store buckets instead of failing to open the store
  • lore-server: add Cache-Control headers to the presigned-URL redeem endpoint for immutable content
  • Add a self-contained Terraform example for an AWS primary + edge deployment under contrib/aws/ Fixes & Improvements
  • lore-storage: read_into now respects the requested byte range for single-fragment reads (partial reads of files ≤ 256 KiB no longer fail)
  • lore-server: fix JWK refresh cache check so a missing/rotated key triggers a fetch, allowing key rotation without a restart
  • lore-credential: require a DNS label boundary when matching a dotless JWT aud, and allow exact apex-domain matches, closing an audience-suffix leak
  • lore-revision: preserve dirty move status through status --scan instead of degrading it to delete + add
  • lore-revision: bound commit read memory with a travelling fragment permit, and cap directory recursion fan-out during commit
  • lore-revision: drain staging tasks on all error paths so failures propagate cleanly
  • lore-storage: batch FastCDC chunking to cut per-chunk overhead on medium/large writes
  • Add transport connect timeouts so local reads no longer stall on an unreachable remote
  • lore: use the calling process's working directory for absolute-path resolution in the service process
  • Fix lore_branch_switch and lore_branch_reset to restore the branch name→id mapping (so the branch appears in the local list), with a --force override
  • lore-revision: fix restore failing with Dirty node remain after nodes were committed
  • lore-base: update vendored rpmalloc to 2.0.1
