Remove protocol version field from `StAnnTx` types
Use precomputed plutus contexts in Alonzo UTXOS
Introduce `LEDGERS` for Alonzo and pass `unsafeLinearExtendEpochInfo`
in `mkStAnnTx`
Extract signal-generation function in shelley trace generation
so it can be reused in Alonzo
Deprecate old `applyTx` and `Validated`-based `Mempool` API
Migrate uses of to-be-deprecated functions from `Mempool` module
Adjust instances of refactored `ApplyTx` class for all eras
Simplify imports in `Mempool` module
Introduce user-facing replacements to `applyTx` and `reapplyTx`
Add `internalReapplyValidatedTx` to `ApplyTx`
for more per-era control over revalidation of transactions
Qualify `Babbage.UTXO` import in Conway `Utxos`
Re-export deprecated rule names from Shelley API
Since `Cardano.Ledger.Shelley.API` will be removed, we would like to keep re-exporting the deprecated names which will force us to change the imports at other places.
Add `internalApplyTxWithValidation` to `ApplyTx`
to replace `applyTxValidation`, operating on `ValidatedTx`. Define `applyTxValidation` in terms of `applyTxWithValidation`
Add Dijkstra rule deprecation helpers
