Cortex is betting on Parquet block storage and graduating years of experimental features.
A side-by-side editorial comparison of Apache HertzBeat and Graphite — release velocity, themes, recent moves, and the top alternatives to consider.
A monitoring project whose public release feed skips the release that mattered.
HertzBeat's tracked entries cover four release candidates, and the record is patchy — v1.7.1 through v1.7.3 in mid-2025 carry no notes beyond a merge commit or a signoff line, then an eleven-month gap to v1.9.0-rc1 in July 2026. The 1.8.0 release never appears in the feed at all despite v1.9.0-rc1's own changelog referencing 1.8.0 documentation and download page updates, so this record is missing a version. What v1.9.0-rc1 does show is a split of hertzbeat-common into core and Spring modules, monitoring template fixes and broad internationalization work.
Graphite's answer to its own CVE backlog is a pre-release nobody calls official.
Graphite's release feed shows three entries across four years. The last tagged work is a pair of 1.2.1 pre-releases whose own notes decline to call them official: they exist, in the maintainer's words, as a master-branch milestone for people who want to avoid CVE checks against 1.1.x, with the second adding XSS fixes. Both point at a single open discussion thread about the state of the project.

What v1.9.0-rc1 does show is a split of hertzbeat-common into core and Spring modules, monitoring template fixes and broad internationalization work.
The visible direction is structural cleanup rather than new monitoring coverage — separating framework-agnostic code from Spring-specific code is the kind of refactor a project does when it wants the core embeddable elsewhere. The internationalization work and Apache graduation blog point at a project investing in the things that widen a contributor base. The revert of MongoDB user account metrics within the same candidate suggests new collectors still land unevenly.
Expect the common module split to continue and MongoDB account metrics to return once the issue behind the revert is resolved. The missing 1.8.0 entry is a feed gap worth confirming before treating the eleven-month silence as real.

Both point at a single open discussion thread about the state of the project.
This is a project whose maintenance and its release process have come apart. The security fixes are real and are in master, but nothing has been promoted to a release users can adopt through normal channels, which leaves operators choosing between a version that fails CVE scans and an explicitly unofficial tag. The four-year gap since the 1.1.9 preparation commit is the clearest signal available.
Nothing in these entries supports a confident call on a 1.2.1 final; the maintainer has pointed the question at a discussion thread rather than a roadmap.
