    statements (bug #370)

    totals

  + Make automated transactions work with assertions (bug
    #1127)

  + Improve parsing of date tokens (bug #1626)

  + Don't attempt to invert a value if it's already zero
    (bug #1703)

  + Do not parse user-specified init-file twice

  + Fix parsing issue of effective dates (bug #1722,
    TALOS-2017-0303, CVE-2017-2807)

  + Fix use-after-free issue with deferred postings (bug
    #1723, TALOS-2017-0304, CVE-2017-2808)

  + Fix possible stack overflow in option parsing routine
    (bug #1222, CVE-2017-12481)

  + Fix possible stack overflow in date parsing routine (bug
    #1224, CVE-2017-12482)

  + Fix use-after-free when using --gain (bug #541)

  + Python: Removed double quotes from Unicode values.

  + Python: Ensure that parse errors produce useful
    RuntimeErrors
