What is NGINX?

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

What is rsyslog?

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

5.0

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

◆ Current state

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

◆ Where it's heading

HTTP/3 has needed fixes in each of the last three mainline releases, two of them CVEs. Mainline is adding features and removing legacy code at the same time, while stable gets the CVE backports.

◆ Prediction

More HTTP/3 fixes on both lines are likely; on mainline, follow-up work on the control API and JSON module is the next feature thread to watch.

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

◆ Current state

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

◆ Where it's heading

Across 2026 rsyslog has moved from a host syslog daemon toward a container and cloud log shipper, adding inputs for Kubernetes and outputs for AWS services each cycle. Queueing is the other active area.

◆ Prediction

The next scheduled-stable snapshot is due in December on the two-month rhythm; which outputs it adds is unclear from the feed.
