What is Fluentd?

Fluentd's newest line spent its last release hardening the paths that accept untrusted data.

Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.

What is NetBird?

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

Fluentd's newest line spent its last release hardening the paths that accept untrusted data.

◆ Current state

Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.

◆ Where it's heading

The feature work landed in 1.19.0 — zstd compression across buffer, out_file, out_forward and in_forward, chunk evacuation when the retry limit is hit, TLS 1.3 in out_http — and everything since has been reliability and input validation. That ordering makes sense for a log collector: the interesting failure modes are decompression bombs, path traversal through tag names, and sockets that never close, not missing features. Ruby 4.0 compatibility work is threaded through the recent releases.

◆ Prediction

Expect 1.19.x to keep shipping validation and socket-lifecycle fixes with Ruby 4.0 support consolidating, and 1.16.x to receive only isolated backports.

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

◆ Current state

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

◆ Where it's heading

After v0.81 focused on device trust through certificate posture checks, v0.82 is about the management plane's storage and on hardening the built-in SSH server. Deprecating Rosenpass signals a change in how NetBird approaches post-quantum key exchange, though the entries do not name the replacement.

◆ Prediction

Expect v0.82.0 final with the MySQL removal intact, and a later release introducing the Rosenpass replacement.
