A PSBT test vector arrives because a bug got past the old ones
BIP-174 gains a combiner vector for the sighash type, plus an instruction to run the existing vectors in both orders - because Combine is not commutative and the tests were.

BIP-138 encrypts the part of a wallet backup that is not the seed
A new draft BIP defines a compact encryption scheme for output script descriptors, wallet policies and other metadata. The payload is forbidden from containing private key material.
The descriptor BIPs are reclassified from Standard to Specification
A merge into the BIPs repository moves BIP 379 through BIP 390 to the Specification type introduced by the revised BIP process.
A new BIP lands for encrypting the wallet data that is not the seed
BIP-138, merged into the BIPs repository, specifies a compact encryption scheme for non-seed wallet data such as descriptors.
A BIP-352 reference fix stops the silent-payments test asserting on nothing
The change guards an assertion in the silent-payments reference code so it only runs when the optional expected value is present, instead of dereferencing a None.
BIP-374 now reduces its challenge modulo the curve order
The discrete log equality proof spec went to version 0.3.0: the challenge is reduced mod n on generation, a verifier must reject e above the order, and test vectors cover both cases.
