alloy-rs/alloy v2.0.0 on GitHub

This new major release includes several breaking changes as preparation for the Glamsterdam hardfork.

Notable breaking changes are:

network transaction-builder traits were reshaped: TransactionBuilder was split, network-specific methods moved to NetworkTransactionBuilder, and Network bounds tightened around TransactionRequest / TxEnvelope (#3344, #3723).
Blob transaction APIs changed: TransactionBuilder7594 was folded into TransactionBuilder4844, blob-sidecar methods were renamed/specialized, the default TxEip4844Variant generic changed, and PooledTransaction now uses the EIP-7594 sidecar type (#3600, #3328, #3468).
AnyTransactionReceipt is now a dedicated struct instead of a type alias, so code that relied on alias semantics or direct wrapped-type usage needs updating (#3153).
ChainConfig is now non-exhaustive, and Amsterdam support adds new header/config fields plus new BlockHeader requirements; exhaustive struct literals, pattern matches, and custom header impls may need changes (#3566, #3871).
Provider builder / filler APIs changed: .network() now replaces the filler stack, and GasFiller is no longer a unit struct, so .filler(GasFiller) becomes .filler(GasFiller::default()) or custom estimator wiring (#3686, #3849).
AnyNetwork no longer silently signs or re-encodes unknown transaction types; those paths now fail fast (#3794).
muxTracer now keys mux configs / frames by GethDebugTracerType instead of GethDebugBuiltInTracerType, which breaks existing tracer map code (#2442).
Pubsub / RPC surface types gained new variants and fields, including transactionReceipts subscriptions and newer header / transaction fields, so exhaustive enum matches and struct literals may need .. / wildcards (#3410, #3707, #3871).
