What is Barman?

Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.

Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.

What is NATS?

NATS second release candidates add a config reload check and faster redelivery queues.

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.

◆ Current state

Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.

◆ Where it's heading

After closing the cloud backup-and-restore loop in 3.18 and 3.19, Barman is hardening it for regulated, least-privilege setups: customer-supplied keys, data kept on Outposts, and now a fix aimed exactly at deployments where the uploading identity has fewer rights than Barman. Releases come roughly every two to three months.

◆ Prediction

A 3.21.0 feature release is the likely next step on the usual cadence, probably continuing cloud storage and retention safety work.

5.0

NATS second release candidates add a config reload check and faster redelivery queues.

◆ Current state

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

◆ Where it's heading

The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.

◆ Prediction

Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
