What is Apereo CAS?

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

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.

2.5

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

◆ Current state

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

◆ Where it's heading

Candidates arrive about monthly, and 8.1 has overtaken 8.0 as the active line. Without notes in the entries, the feed tracks timing rather than content.

◆ Prediction

An 8.1.0-RC4 or an 8.1.0 final is the next likely entry, on the same roughly monthly rhythm.

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.
