Prometheus vs RaspAP: at a glance
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 RaspAP?
RaspAP folded its Insiders-only features into the open release, then rebuilt its VPN handling.
RaspAP 3.5.6 in late September merged the Insiders-exclusive features into the public release. 3.5.8 followed with a command-injection fix in SSID and OpenVPN handling, and 3.5.9 on 1 November is the largest release in the feed: dozens of pull requests, most from one contributor, fixing the WireGuard kill switch, adding an uplink watchdog, NetworkManager support for Wi-Fi client networks, captive-portal access for AP clients while the kill switch is on, and login protection for the QR code pages.

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.
RaspAP
2.5DEVOPS
RaspAP folded its Insiders-only features into the open release, then rebuilt its VPN handling.
◆ Current state
RaspAP 3.5.6 in late September merged the Insiders-exclusive features into the public release. 3.5.8 followed with a command-injection fix in SSID and OpenVPN handling, and 3.5.9 on 1 November is the largest release in the feed: dozens of pull requests, most from one contributor, fixing the WireGuard kill switch, adding an uplink watchdog, NetworkManager support for Wi-Fi client networks, captive-portal access for AP clients while the kill switch is on, and login protection for the QR code pages.
◆ Where it's heading
Two changes stand out. The sponsor-only Insiders tier no longer holds features back from the open release, which changes what the free version is. And the work has moved from the dashboard refactor of 3.5.4 into networking correctness: VPN routing, kill-switch rules and interface detection, the parts that break in real deployments with VPNs and Wi-Fi 7 access points.
◆ Prediction
Expect more VPN and routing fixes in 3.5.x as the kill-switch and NetworkManager changes meet more setups. The entries don't say how the Insiders program works now that its features are public.
