Releasing Octez v12.1

The limit on the size of metadata stored by a node, introduced by Octez v12.1, causes some RPCs to occasionally return "too large". This is intended behavior but it is also a breaking change for certain applications including indexers.

We have released Octez v12.2 which addresses this issue, by making the size limit configurable and increasing its default value.

Note: blocks that have been stored using Octez v12.1 are not retroactively filled with the missing metadata.
