26 September 2023 (Puppet Application Manager 1.102.2)

New in this release:

Migrated from Weave to Flannel. Flannel has replaced Weave as the Kubernetes CNI on Puppet-supported clusters, as Weave is no longer supported. The installation has additional interactive prompts to support this change.
Important upgrade information:
- IPv6 and dual-stack networks are not supported on Flannel.
- Pod-to-pod networking now depends on UDP port 8472 being open instead of ports 6783 and 6784.
Added a host preflight. Added a host preflight in the installer to stop installation if the installer detects the presence of a default REJECT rule in the FORWARD chain of iptables.
Important upgrade information: This is a known issue with the Flannel installation. To check for a REJECT rule in the FORWARD chain of iptables, run:
```
iptables -vL FORWARD
```
If there are any REJECT rules, those rules must be removed prior to the upgrade. They can be restored afterwards.

Important: Version 1.0.2 of the puppetlabs/pam_firewall module is now available. To avoid conflicts, upgrade the module before upgrading Puppet Application Manager to version 1.62.0.

New in this release:

Kubernetes version upgrade. For standalone and HA installations, this version includes an upgrade of Kubernetes to version 1.21.8.
Important upgrade information: The upgrade process takes place on all nodes, and first upgrades Kubernetes to version 1.20 before upgrading to version 1.21.8. For a three-node cluster, you can expect the upgrade process to take around an hour. Confirmations are required during the upgrade process.
For legacy installations (installed before May 2021), this version includes an upgrade of Kubernetes to version 1.19.15.
Tip: See How to determine your version of Puppet Application Manager if you're not sure which installation type you're running.
Prometheus enabled on standalone architecture. Beginning with version 1.62.0 Prometheus is enabled by default on all new and existing standalone Puppet Application Manager installations. Prometheus requires an additional 350m CPU and 500MiB of memory, so ensure your system is properly sized before upgrading. Prometheus is an optional component; if you need to disable it to conserve resources, see Optional components.
Automatic certificate rotation. By default, the self-signed certificates used by Project Contour and Envoy expire after one year. This version includes an update that auto-rotates those certificates before they expire.
Component upgrades to address CVEs. To address various CVEs, this version includes an upgrade of containerd to version 1.4.12.
Other component upgrades. This version includes an upgrade of KOTS to version 1.62.0.

Deprecated in this release:

Legacy architecture. The legacy architecture, which was the version of Puppet Application Manager available for installation prior to May 2021, is now deprecated. (See How to determine your version of Puppet Application Manager if you need to confirm whether you're running the legacy architecture.) The legacy architecture utilizes Rook 1.0, which is incompatible with Kubernetes version 1.20 and newer versions. Kubernetes version 1.19 is no longer receiving security updates. Puppet will continue to update legacy architecture components other than Kubernetes until 30 June 2022. If security advisories against Kubernetes 1.19 arise, the remediation path is to migrate to one of the newer architectures by following the instructions in Migrating PAM data to a new system.
Important: Before beginning the migration process from a legacy deployment you must upgrade to PAM version 1.62.0 with the force-reapply-addons flag included in the upgrade command. Find upgrade instructions at PAM legacy upgrades and PAM offline legacy upgrades.

Rook upgrades. This version includes an upgrade of Rook in the high availability architecture to 1.5.11 and the version of Rook in the legacy architecture to 1.0.4-14.2.21. These upgrades address a vulnerability in Ceph components (CVE-2021-20288).

```

26 May 2021

New in this release:

runC. The version of runC has been upgraded to v1.0.0-rc95 to address CVE-2021-30465.

Known issues in this release:

Running the KOTS installer with the airgap and kurl-registry-ip flags results in an error.

10 May 2021 (Puppet Application Manager 1.40.0)

New in this release:

Distinct architectures for standalone and high availability deployments of the Puppet Application Manager platform. Standalone supports lower system requirements and resolves inherent flaws in using Ceph on a single node. High availability uses an updated version of Rook for faster, more reliable distributed storage.
Note: It is not possible currently to upgrade to these architectures from existing installations. However, migrating applications between them is on the roadmap for a future release.
The previous architecture is maintained as the legacy configuration. This version includes an upgrade of Kubernetes to 1.19.10; this upgrade process upgrades through Kubernetes 1.18, and happens on all nodes. It can take ~1 hour to do for a 3-node cluster, and requires confirmations during that period. It also includes an upgrade of Project Contour to version 1.14.1, adds Metrics Server 0.4.1, an upgrade of ekco to 0.10.1, and an upgrade of Prometheus to 2.26.0.
