Weaver 0.16.3 release notes

Downloads and queue

Responsive downloads on slow storage. Decoded batches now write on the
disk owner thread without blocking the pipeline, keeping dispatch, status
updates, and the UI responsive while writes finish.
Fix a queue stall under write pressure. When the highest-priority job
cannot use a server, that server can continue downloading other eligible
jobs. Soft pressure limits each handout to one article instead of leaving
the connection idle against a backlog it cannot drain.
Safer write completion and repair. Pending writes finish before archive
demotion, PAR3 source publication, or shutdown proceeds. Damaged-segment
writes avoid clean ranges still being written, removed jobs retain their
memory accounting until writes finish, and failed handback writes fail the
job instead of only logging an error.
Correct paused-job responses. Jobs added paused, including duplicates
held back by duplicate handling, immediately report Paused even before
the queue has admitted them.

Windows tunnel revocation. Refresh the connection state of duplicated
sockets so revoking a tunnel closes connections that have just finished
connecting.
Certificate trust updates. Update certificate validation and root stores
to remove distrusted emSign intermediates and address
RUSTSEC-2026-0381, RUSTSEC-2026-0382, and RUSTSEC-2026-0383.
Older Linux kernels. Enable the secure-randomness fallback in the static
musl builds for systems without the required entropy syscall support.

Unified accelerated CRC checks. Use crc-turbo for yEnc, archive, and
recovery checksums, including CRC combination and zero-filled ranges. Kernel
diagnostics report the selected tier and any CRC_TURBO_TIER override.
Archive library updates. Update the RAR, 7z, LZMA, PAR2, and PAR3 engines,
including explicit wiping of RAR member cipher keys when they are dropped.
More reliable validation. Build and pull end-to-end test images for the
host architecture by default, and remove timing races from disk-write
accounting and proxy fallback tests.
