# v2.0.3..v2.1.0-rc.1 Notes ## Significant L1 Changes ### 1. **Rollup Contract Interface Changes** - **`propose()` function signature changed**: Now requires an additional `_attestationsAndSignersSignature` parameter - **`validateHeaderWithAttestations()` function signature changed**: Also requires the new signature parameter - This affects any code that directly calls these functions on the rollup contract ### 2. **New Required Configuration Parameters** Several new configuration parameters are now required for deployment: - `localEjectionThreshold`: Stricter ejection threshold local to specific rollup (default: 196,000 tokens) - `slashingDisableDuration`: How long slashing can be disabled in seconds (default: 5 days) ### 3. **GSE Contract Changes** - **New function**: `setProofOfPossessionGasLimit()` \- allows governance to adjust gas limits for BLS proof validation - **Gas-limited proof validation**: Proof of possession validation now has configurable gas limits (default: 200,000 gas) ### 4. **Validator Queue Management Changes** - **`flushEntryQueue()` behavior changed**: Now has an overload accepting a `_toAdd` parameter to limit validator additions - **New validator flush accounting**: System now tracks available validator flushes per epoch Significant Non-Breaking Changes -------------------------------- ### 1. **Enhanced Slashing Controls** - **Temporary slashing disable**: Vetoers can now temporarily disable slashing for the configured duration - **New function**: `setSlashingEnabled(bool)` for controlling slashing state ### 2. **Improved Validator Selection** - **Configurable lag period**: Validator sampling now uses configurable epoch lag instead of fixed 2-epoch delay - **Better bootstrapping**: Enhanced validator set bootstrapping with improved flush size calculations ### 3. **Updated Default Values** - **Coin issuer rate**: Updated to `25,000,000,000 tokens / year` (approximately 793 tokens per second) - **Local ejection threshold**: Set to 196,000 tokens (stricter than global 50,000 threshold) ## Significant Node Changes ### Fixes - Rollback world state on failed block sync – Prevents bad state persistence by rolling back uncommitted data if block sync fails. [(#17158)](github.com//pull/17158) - Early rejection of duplicate nullifiers – Detects and rejects transactions with duplicate nullifiers before inclusion. [(#17157)](github.com//pull/17157) - Watcher pruning fix – Watcher now re-executes only blocks from the relevant pruned epoch, avoiding cross-epoch slashing issues. [(#17145)](github.com//pull/17145) - Improved proposal validation – Fully validates proposal headers (including archive root derivation) and blocks attempts to reuse existing block numbers. [(#17144)](github.com//pull/17144) - L1 to L2 message sync reliability – Waits for rollup to reach the inbox block before marking L1→L2 messages as synced; adds helpers to track message readiness. [(#17132)](github.com//pull/17132) - Slashing round recovery – Executes pending slashing rounds skipped during the first executable round; adds slashExecuteRoundsLookBack to control re-check depth. [(#17125)](github.com//pull/17125) - Broker restart on rollup change – Ensures broker restarts when rollup chain changes to stay synchronized. [(#17120)](github.com//pull/17120) - Remote signer readiness check – Verifies that a remote signer is available before use. [(#17119)](github.com//pull/17119) - Orchestrator and agent retry improvements – Makes connections to the broker more robust under transient failures. [(#17117)](github.com//pull/17117) - Telemetry cleanup – Fixes incorrect or spammy telemetry warnings. [(#17155)](github.com//pull/17155) ### Features - Network configuration support – Introduces centralized configuration for network parameters.
