Prefect

This release includes the ability to easily orchestrate flow runs for deployments from other flow runs! If you're currently using `OrionClient.create_flow_run_from_deployment`, or if that's been too complicated, you'll be excited to see our sync-compatible `run_deployment` function that links created runs as subflows. There are a bunch of other enhancements and fixes too! Check out the [release notes](https://github.com/PrefectHQ/prefect/blob/main/RELEASE-NOTES.md#release-250) for details.

This release disables block protection. With block protection enabled, as in 2.4.3 and 2.4.4, client and server versions cannot be mismatched unless you are on a version before 2.4.0. Disabling block protection restores the ability for a client and server to have different version.

Block protection was added in 2.4.1 to prevent users from deleting block types that are necessary for the system to function. With this change, you are able to delete block types that will cause your flow runs to fail. New safeguards that do not affect client/server compatibility will be added in the future.

Note this release also restores block memoization by default, reverting the change in 2.4.4 as it did not patch the issue as intended.

**When running a server with this version, the client _must_ be the same version.** This does not apply to clients connecting to Prefect Cloud.

This release attempted to fix a bug affecting a subset of users on 2.4.3 where block schemas cannot be saved. This release did not address the issue as intended and is fixed in 2.4.5.

**When running a server with this version, the client _must_ be the same version.** This does not apply to clients connecting to Prefect Cloud.
