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.
