What is Fluentd?

Fluentd 1.20 drops its yajl dependency to keep building on Ruby 4.1

Fluentd shipped 1.20.0 and 1.20.1 on the same day in late October. 1.20.0 replaces yajl with Ruby's built-in JSON, adds opt-in threaded parsing and directory watching to in_tail, a command timeout for in_exec, TCP keepalive for out_forward, a umask option and a cap on evacuated buffer chunks. 1.20.1 removed yajl-ruby from runtime dependencies because it cannot build on Ruby 4.1, so plugins that require it must now declare it themselves. 1.19.4 in September fixed buffer accounting leaks, a path traversal check and syslog limits.

What is Gitness?

Harness Open Source last shipped in August 2025, on this feed at least

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

Fluentd 1.20 drops its yajl dependency to keep building on Ruby 4.1

◆ Current state

Fluentd shipped 1.20.0 and 1.20.1 on the same day in late October. 1.20.0 replaces yajl with Ruby's built-in JSON, adds opt-in threaded parsing and directory watching to in_tail, a command timeout for in_exec, TCP keepalive for out_forward, a umask option and a cap on evacuated buffer chunks. 1.20.1 removed yajl-ruby from runtime dependencies because it cannot build on Ruby 4.1, so plugins that require it must now declare it themselves. 1.19.4 in September fixed buffer accounting leaks, a path traversal check and syslog limits.

◆ Where it's heading

The project is clearing old native dependencies ahead of new Ruby versions while making in_tail cheaper at high file counts. The hardening theme from 1.19.3 and 1.19.4 continues in the buffer and input paths.

◆ Prediction

Expect 1.20.x patches driven by plugins that break without yajl-ruby, since 1.20.1 pushes that dependency onto plugin authors.

Harness Open Source last shipped in August 2025, on this feed at least

◆ Current state

The feed holds two releases of Harness Open Source, tracked here as Gitness. v3.2.0 in May 2025 added Git LFS, default reviewers through branch rules and a Revert PR option; v3.3.0 that August added tag rules, a PR dashboard upgrade with favourite repositories, and a fix for a Git LFS upload path flaw. Nothing newer appears here.

◆ Where it's heading

Both releases deepen code-hosting governance: branch rules, then tag rules, plus review routing through Code Owners. That is parity work against established Git hosts rather than a new direction. With entries more than a year old, the feed shows where the project was heading in 2025, not where it is now.

◆ Prediction

The entries do not support a confident call: there is no release in this feed after v3.3.0, so it is unclear whether the project slowed or the feed stopped tracking it.
