The latest demo was for 2.11.0. Even that I guess since the v2 is in maintain mode, there will be no video...


System demos are typically held the week after a minor release becomes available. Check the [Open Mainframe Project Calendar](https://zoom-lfx.platform.linuxfoundation.org/meetings/zowe) for the latest schedule.

We shouldn't mentioned this one. I made a mistake. There is no functional change, it is just fix for pipeline/testing. It doesn't worth to be here.

It is more detail message than in the original APIML's changelog. We should change the text in there as well

Original text: Fix URLs for onboarding when AT-TLS is enabled and gateway read a keyring with empty values

There are two issues:

  • a wrong Gateway URL in API Catalog when AT-TLS is enabled
  • a startup issue is ICSF keyring is used

This text looks to me that the issue are releated, but not.

Ok. I changed this to:

"Fixed an incorrect Gateway URL in API Catalog when AT-TLS is enabled, and a startup issue when ICSF keyring is used."
Please verify if this is correct. Thanks

* Fixed correct protocol scheme in hybrid AT-TLS setup. ([#4338](https://github.com/zowe/api-layer/issues/4338))

### Vulnerabilities fixed

Zowe discloses fixed vulnerabilities in a timely manner giving you sufficient time to plan your upgrades. Zowe does not disclose the vulnerabilities fixed in the latest release as we respect the need for at least 45 days to decide when and how you upgrade Zowe. When a new release is published, Zowe publishes the vulnerabilities fixed in the previous release. For more information about the Zowe security policy, see the [Security page](https://www.zowe.org/security.html) on the Zowe website.

The following security issues were fixed by the Zowe security group in version 2.2.
