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 HAProxy Kubernetes Ingress Controller?

Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies

The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.

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.

H5.0

Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies

◆ Current state

The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.

◆ Where it's heading

The ssl-passthrough theme has faded, and the series is now closer to routine upkeep than stabilization. Fixes have moved to ingress class handling, TLS secret storage and concurrency, with test coverage arriving in the same changes. Patches keep coming, but no new configuration surface has appeared on this line in the entries shown, apart from amending the SSL frontend through a custom resource in v3.2.15.

◆ Prediction

Expect further patches dominated by go.mod and Kubernetes client updates, with new capability waiting for a later line.
