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.
What is Rollbar?
Rollbar now runs Resolve by itself: a new error can become a fix PR with no one starting it
Agent Automation, released in September, lets teams set rules so a matching error triggers root cause analysis and then Resolve, which opens a pull request for review. Rollbar can post the result to Slack, and a merged fix resolves the item. October's work is plumbing around that loop: personal API tokens, item history and comments through the API, Metrics API queries across all projects, and faster Analyze queries. Analyze is now included in every Advanced and Enterprise plan.

NATS
5.0DEVOPS
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.

Rollbar now runs Resolve by itself: a new error can become a fix PR with no one starting it
◆ Current state
Agent Automation, released in September, lets teams set rules so a matching error triggers root cause analysis and then Resolve, which opens a pull request for review. Rollbar can post the result to Slack, and a merged fix resolves the item. October's work is plumbing around that loop: personal API tokens, item history and comments through the API, Metrics API queries across all projects, and faster Analyze queries. Analyze is now included in every Advanced and Enterprise plan.
◆ Where it's heading
The error-to-fix loop has moved from human-started to rule-started, with humans kept at the merge step. The API work supports the same direction: automated checks can now read an item's history and write comments on it. Personal tokens scoped to what a user can reach also suit scripts and agents better than shared account tokens. Bundling Analyze removes an add-on from the top plans.
◆ Prediction
Resolve adoption will depend on how often rule-triggered PRs get merged, so expect finer rule controls and reporting on those runs. Rule history pages with CSV export are an early sign.
