- ledger 2: entries contain transactions
- hledger 0.4: Entrys contain RawTransactions (which are flattened to Transactions)
- ledger 3: transactions contain postings
- hledger 0.5: LedgerTransactions contain Postings (which are flattened to Transactions)
- hledger 0.8: Transactions contain Postings (referencing Transactions..)
