ReleasePort's take

Light signal

editorial:auto 10d

ReleasePort Layer 1 v1.3.0 adds cron scheduling for email downloads and introduces several performance optimizations across the Tokio runtime, memdb layer, BlobManager I/O, Tantivy indexing, and WAL flushing.

Why it matters: Enables automated, scheduled email download workflows (key for batch processing) while improving latency on low‑core systems, reducing blocking in Tokio workers, batching memdb commits (100 ops/10 s), offloading BlobManager writes, and ensuring clean shutdown of the memdb WAL.
