**Full Changelog**: https://github.com/flyteorg/flytekit/compare/v1.2.15...v1.2.16

As mentioned in the [1.2.14 release notes](https://github.com/flyteorg/flytekit/releases/tag/v1.2.14), official support for protobuf3 ended in 23Q2. This release backports the 1.6.1 and 1.6.2 releases, concluding then our support for protobuf3.

Only critical or security fixes will warrant another 1.2.x release going forward.

As official support for protobuf3 [ends in 23Q2](https://protobuf.dev/support/version-support/#python), this release marks the end of support for protobuf3.

We're backporting the majority of changes that made to the flytekit 1.7.0 [release](https://github.com/flyteorg/flytekit/releases/tag/v1.7.0), the major exception being the work to support agents.

As mentioned in [flytekit 1.3.0 release](https://github.com/flyteorg/flytekit/releases/tag/v1.3.0), we'll be backporting flytekit releases to the 1.2 release. This release is targeted at flytekit users who for some reason cannot upgrade to the new major version of the protobuf library. In this specific case we're backporting all changes announced in the [1.6](https://github.com/flyteorg/flytekit/releases/tag/v1.6.0) release.
