What is NATS?

NATS 2.15.3 and 2.14.10 go final with a reload check and lighter JetStream scans.

NATS released 2.15.3 and 2.14.10 on November 11 after two release candidates each. Both bring optional client-certificate verification, account-hash subject mappings, configurable leafnode and gateway ping intervals, and JetStream filestore scans that skip non-matching messages. 2.15.3 also adds the -t --test_reload flag that says whether a config change needs a restart.

What is Apache Arrow Rust?

Arrow Rust cuts release candidates on three older lines at once.

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

NATS vs Apache Arrow Rust: editorial side-by-side

N
NATS
DEVOPS
5.0

NATS 2.15.3 and 2.14.10 go final with a reload check and lighter JetStream scans.

◆ Current state

NATS released 2.15.3 and 2.14.10 on November 11 after two release candidates each. Both bring optional client-certificate verification, account-hash subject mappings, configurable leafnode and gateway ping intervals, and JetStream filestore scans that skip non-matching messages. 2.15.3 also adds the -t --test_reload flag that says whether a config change needs a restart.

◆ Where it's heading

NATS runs two supported lines in lockstep, with RCs every few days before each patch. The work is operator-focused: multi-tenant account mappings, health checks for leafnodes and less JetStream overhead under large backlogs. New operator tooling lands on 2.15 first.

◆ Prediction

Expect quiet weeks of maintenance and then the next RC pair for 2.15.4 and 2.14.11, likely with more JetStream filestore tuning.

A5.0

Arrow Rust cuts release candidates on three older lines at once.

◆ Current state

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

◆ Where it's heading

The project keeps four major lines alive and patches them together, so downstream users on older Arrow versions still get fixes. Feature work stays on the 60 line.

◆ Prediction

Expect the three patch releases to publish after the vote period, and a 60.2.0 or 61.0.0 candidate to follow.
