2.4

For details on the changes see NEWS:

• Both "-$100.00" and "$-100.00" are now equivalent amounts.
• Simple, inline math (using the operators +-/*, and/or parentheses) is supported in transactions.
• Use of a "catch all" account is now possible, which auto-balances entries that contain only one transaction.
• Entries that contain a single transaction with no amount now always balance, even if multiple commodities are involved.
• Fixed several bugs relating to QIF parsing, budgeting and forecasting.

2.3

• The directive !alias ALIAS = ACCOUNT makes it possible to use
  "ALIAS" as an alternative name for ACCOUNT in a textual ledger file.
  You might use this to associate the single word "Bank" with the
  checking account you use most, for example.
• The --version page shows the optional modules ledger was built with.
• Fixed several minor problems, plus a few major ones dealing with imprecise date parsing.

2.2

For details on the changes see NEWS.

2.1

• Improved the autoconf system to be smarter about finding XML libs
• Added --no-cache option, to always ignore any binary cache file
• `ledger-reconcile' (in ledger.el) no longer asks for a number of days
• Fixed %.XY format, where X is shorter than the string generated by Y
• New directive for text files: D <COMM> specifies the default commodity
  used by the entry command

2.0

This version represents a full rewrite, while preserving much of the
original data format and command-line syntax. There are too many new
features to describe in full, but a quick list: value expressions,
complex date masks, binary caching of ledger data, several new
reporting options, a simple way to specify payee regexps, calculation
and display predicates, and two-way Python integration. Ledger also
uses autoconf now, and builds as a library in addition to a
command-line driver.

1.7

• # histories are now supported, so that ledger remembers the
  historical prices of all commodities, and can present register
  reports based on past and present market values as well as original
  cost basis. See the manual for more details on the new option
  switches.
