# v1.6.2

## Major 📜

### 🗳️ Stable validator slots (epoch 877)

• Each epoch's validator set is now a fixed roster + active mask — a slash clears one bit instead of rewriting the list
• Signer indexes stay valid for the whole epoch, even across slashes; quorum counts active validators only
• Several slashes in one block now accumulate (previously the last one overwrote the others)
• Aggregate signatures carry mask_active; mask_size / mask_set_size are derived, no longer sent
• slash_trainer and contract deploy drop their fixed 0.01 AMA exec fee — it exceeded the 0.002 AMA exec cap, so neither could ever succeed. Metered DB/storage costs still apply
• Slash txs attach gas to cover writing the new validator record

### 📥 Sync inbox

• Incoming blocks, attestations and consensuses land in an in-memory inbox (3 GB cap), not RocksDB
• Signatures, hashes and txs are checked on arrival, in parallel; validator-set checks run only when it's the next block to apply or root
• Blocks far ahead of the tip never touch the database; competing forks are kept until finality and re-verified after a softfork
• When full, the furthest heights are evicted first, so the next blocks always fit
• Catchup no longer re-requests blocks already buffered

### 🔁 Faster catch-up

• Bulk block fetching is no longer starved while blocks are being applied

## Fixes & hardening 🔧

• Pruner: drops rewind data (muts_rev) below the previous epoch — a rewind never goes below the root
• HTTP keep-alive: fixed body reads across keep-alive requests; memory released between requests
• Slash motions: signed for the correct epoch at the epoch boundary; dropped if the validator set or parent block changes mid-motion
• Bootstrap: default snapshot height 85,800,302;
