Release WojakCoin Core 1.21.3.0 — MINERS/POOLS UPDATE BEFORE 180000 · WojakCoinProj/wojakcore

Caution

🚨 MINERS / POOLS: UPDATE TO 1.21.3.0 BEFORE BLOCK 180,000

Height	Rule
180,000	Dev fund 90/8/2 (miner / LP pool / dev vault)
190,000	15-min max future block time (time-warp mitigation)

Pools: use getblocktemplate — no -mineraddress required. Read the foundation array for non-miner coinbase outputs.

Older software will orphan after these heights. Update now.

Based on the Bitcoin Core 0.21 line (rebase-0.21.2). Tag: 1.21.3.0.

Latest: fix(rpc): update getblocktemplate for mining pool compatibility

Removed -mineraddress CLI option and the GBT requirement for it when the development fund is active
Removed legacy coinbasetxn field from the getblocktemplate response
Added foundation array with payee, script (hex), and amount for dev-fund / non-miner coinbase outputs
coinbasevalue is the total coinbase value (GetValueOut) per BIP 22

Pools no longer need a special node flag; build the coinbase from GBT fields as usual.

DNS seeds: bare-hostname lookup first (legacy pre-0.19 style, compatible with the old WojakCoin dnsseed), then x%x. service-bit filtered fallback
P2P: GetDesirableServiceFlags no longer requires NODE_WITNESS (SegWit never activates on Wojak — SegwitHeight = never), so outbound connections to legacy non-witness peers work again
Consensus: 15-minute max-future-block-time activation moved 175000 → 190000
Dev fund still activates at 180000 (90/8/2 miner / LP pool / dev vault)
macOS Qt: avoid QAction UAF crash on window teardown (hide main window / disconnect overlay before destroying menus)

macOS: Ad-hoc signed. Gatekeeper may warn — right-click → Open (or install under Applications and open the binary).

Rebuilt wojakcore-1.21.3.0-macos-arm64-qt.app.zip and bins from main (e7ecda9 / v1.21.3.0-e7ecda9), including the splash teardown fix for newer macOS (QAction crash on failed/slow init).
Linux/Windows assets unchanged.
