What is Prometheus?
Prometheus 3.16 turns query cost into a setting while its smoothed selectors go stable
Prometheus is working toward 3.16, with rc.2 dated 27 October. The candidate makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits behind --enable-feature=query-cost, and brings metadata-wal-records to Agent mode. The patch tracks are moving separately: 3.15.1 and 3.13.5 both distrust two root CAs after the eMudhra key compromise and rebuild on patched Go releases.
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.

Prometheus 3.16 turns query cost into a setting while its smoothed selectors go stable
◆ Current state
Prometheus is working toward 3.16, with rc.2 dated 27 October. The candidate makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits behind --enable-feature=query-cost, and brings metadata-wal-records to Agent mode. The patch tracks are moving separately: 3.15.1 and 3.13.5 both distrust two root CAs after the eMudhra key compromise and rebuild on patched Go releases.
◆ Where it's heading
The 3.16 notes spend most of their length on correctness and cost rather than new surface: TSDB out-of-order sample loss, exemplar handling in OTLP and OpenMetrics 2.0, and a long list of parser and memory reductions. Query cost limits are the one addition aimed at operators of shared servers, since a limit on execution is a control that sample counts alone never gave them. Start-timestamp handling also keeps widening, now with a per-query header and counter-reset detection on anchored and smoothed selectors, though it stays behind its feature flag.
◆ Prediction
A 3.16.0 final is the next move, given this candidate has reached rc.2. Query cost and start-timestamp handling both remain behind flags in these notes, so expect feedback on those before either becomes a default.

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.
