Fabric CA 1.5.14 Issue
The update in Fabric CA v1.5.14 to not use FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3 by default has caused some issues in the community.
Since v1.3.x was 6 years ago we thought there was no need to use the old compatibility mode by default anymore, since it was meant to be a temporary mode, and deployments could still set FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=true if they really needed it.
However, it turns out some components like fabric-operations-console never updated to use the new authorization header, until the recent v1.0.9-33. And in some deployments (e.g. kubernetes operators) it is not straightforward to update environment variables for a managed pod.
If anybody sees issues related to “
Invalid token in authorization header: Token signature validation failed" when interacting with Fabric CA server please open an issue.

fabric-sdk-py fix merged for the Fabric CA issue mentioned above, this is the last known issue related to the Fabric CA update. The fix also unblocked fabric-ansible-collection.
Proposal - Archive (deprecated) legacy SDK GitHub repositories
fabric-sdk-node, fabric-sdk-java, fabric-sdk-go have been deprecated for several years without much maintenance. They are replaced with fabric-gateway SDK.
RECOMMENDATION - Archive them (they can still be cloned and could be unarchived if a maintainer steps up)
fabric-sdk-py also hasn’t been maintained much, although it hasn’t formally been deprecated and is still used in other community tools such as fabric-ansible-collection
RECOMMENDATION - Deprecate fabric-sdk-py.
