Prometheus vs Meilisearch
Side-by-side trajectory, velocity, and editorial themes.
Prometheus ships 3.13 LTS while hardening the 3.5 line against a steady drip of CVEs
Prometheus is running two supported tracks at once: the long-lived 3.5 LTS, which now takes near-monthly security-only patches, and the new 3.13 LTS, which lands a large batch of PromQL, service-discovery, and TSDB work. The bulk of recent releases are security maintenance and incremental engine improvements rather than new user-facing surface.
The center of gravity is experimental PromQL (start-timestamp-aware rate/increase, smoothed/anchored rate over native histograms, new scalar and search functions) and native-histogram maturation across TSDB and scrape. Alongside that runs a disciplined security cadence — sanitize-html bumps, credential-forwarding fixes on redirects, snappy-decode limits — backported across both LTS lines.
Expect 3.13.x to stabilize out of RC and continue the native-histogram and start-timestamp buildout behind feature flags, with the 3.5 LTS line receiving security-only patches as new CVEs surface.
Meilisearch hardens auth and speeds synonyms as its new settings indexer nears completion
Meilisearch is on a fast weekly point-release cadence centered on engine performance and security. Its new settings indexer reached feature-complete in v1.47, synonym storage was reworked for up to 13x faster search on large synonym sets, and two authentication CVEs were patched across the 1.47 and 1.48 branches. Experimental work on a render-template route and multimodal fragments points at deeper embedder tooling underneath the search core.
The near-term arc is consolidation: finishing the settings-indexer migration, tightening authentication, and stabilizing the S3 snapshot and remote-federated-search paths. The experimental render-template and fragment routes suggest Meilisearch is building out its vector and multimodal search story so document templates and embedders can be tested and iterated before indexing.
Expect v1.50 to graduate some of the experimental render-template and embedder tooling toward stable, while security and settings-indexer hardening continue in the point releases.
