What is Apache HertzBeat?

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.

What is OpenReplay?

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

Apache HertzBeat vs OpenReplay: editorial side-by-side

A2.5

A monitoring project whose public release feed skips the release that mattered.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

ANALYTICS
5.0

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

◆ Current state

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

◆ Where it's heading

The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.

◆ Prediction

Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
