ZIP 204: specify protocol version assignment procedure; ZIP 258: assign NU6.3 protocol versions
Summary Specifies how peer-to-peer protocol version numbers are assigned to network upgrades — a procedure that has been implicit and hand-maintained until now — and assigns the NU6.3 values. ZIP 204 Adds a new "Assigning Protocol Versions to Network Upgrades" section documenting the invariants that protocol version assignments have always satisfied: 1. Zcash range — values are of the form 170000 + n. 2. Per-network monotonicity — strictly increasing per network across upgrades (required for epoch enforcement). 3.

[ZIP 312] Specify key generation, change randomizer handling
Changes to randomizer handling after I realized that it couldn't possibly be generated using the message as an input. It does simplify things too. Some additional fixes (using "Re-Randomized FROST" consistently; updating Owners) fixes #1051 Referenced issue #1051: [ZIP 312] Complete the specification for FROST key generation. This needs to be compatible with quantum resilience.

NU7: ZIP 218 rounding lowers the supply cap that ZIP 237 claims to keep
Found by @str4d. ZIP 218 sets the post-NU7 subsidy to floor(MaxBlockSubsidy / (2·3·2^Halving)), so three 25-second blocks pay up to 2 zatoshi less than one 75-second block. ZIP 218 states the resulting shortfall from MAX_MONEY: 0.6720 + (H_3 − A)/10^8 ZEC, of which 0.1848 ZEC predates NU7. ZIP 237 reissues only the NSM Value Balance: pre-NU6 unclaimed value plus removed funds. The rounding loss never enters it, so Mainnet issuance converges to MAX_MONEY minus 67,200,000 + (4,406,400 − A) zatoshi, where A is the NU7 activation height.
