Subject: [PATCH] BIP-375: update labeled test vectors
Now PSBT_OUT_SP_V0_INFO provides labeled-spend public key not the base-spend
public key.
Modify test vector with labeled-spend key to the same recipient from:
two sp outputs - output 0 uses label=3 / output 1 uses label=1
to:
three sp outputs (same scan key) - output 0 uses label=1, outputs 1 and 2 uses label=2 (same spend key)
This vector excercises the BIP375 sorting outputs with same scan key properly.
The next commit will fix the validation logic and address this failing test.
bump ChangeLog to 0.1.3
