What is CircleCI?

CircleCI Functions: versioned, validated job setup that coding agents can configure.

CircleCI put Functions into beta on November 4: versioned programs that set up what a job needs, such as Node or AWS credentials, pinned like packages and validated before the pipeline runs. Agents can find and configure them through the CircleCI CLI or MCP server, and dependency caching is built in. Late October was spent on the eMudhra distrust across Runner and Server, GitHub check-run fixes and CLI-scripted Slack notifications.

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.

CircleCI Functions: versioned, validated job setup that coding agents can configure.

◆ Current state

CircleCI put Functions into beta on November 4: versioned programs that set up what a job needs, such as Node or AWS credentials, pinned like packages and validated before the pipeline runs. Agents can find and configure them through the CircleCI CLI or MCP server, and dependency caching is built in. Late October was spent on the eMudhra distrust across Runner and Server, GitHub check-run fixes and CLI-scripted Slack notifications.

◆ Where it's heading

CircleCI is redesigning config for a world where agents write it. The October project-creation flow already offered an AI prompt to generate config; Functions add a typed, versioned, checkable unit an agent can pick and validate before pushing. Orbs remain supported, but Functions look like their successor.

◆ Prediction

Expect the function catalog to grow and more agent-facing CLI and MCP commands around it; the entries do not yet show whether orbs will be deprecated.

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.
