v0.11-0  (2019-04-01)

  o returns: 'weights' may now also be a matrix with as
    many rows as 'rebalance.when'. Also, rebalancing at
    the first timestamp is no longer implied (see
    ChangeLog entry of 2018-11-09 for details).

  o position: new argument 'use.names', which allows to
    use names/colnames as instrument information. Also,
    matrix input is now treated specially; see examples at
    http://enricoschumann.net/notes/computing-positions.html

  o NAVseries: new argument 'drop.NA'. Also, if 'NAV'
    inherits from 'btest', the function now calls
    'as.NAVseries.btest'.

  o summary.NAVseries: new argument 'bm' ("benchmark").
    If set, a 'tracking.error' is computed. The summary
    method now can handle several NAVseries as inputs,
    which allows easier comparison of series.

  o as.NAVseries.btest: method gains optional arguments
    'instrument', 'title' and 'description'

  o plot_trading_hours.R: fix axis-tick positions when
    'label' is "days"

  o functions 'scaleTrades' and 'splitTrades' have
    finally been removed (they had not been exported
    for a long time; see ChangeLog entry of 2017-06-23).
    Use drop-in replacements 'scale_trades' and
    'split_trades' instead.

  o split_trades: 'price' may now be missing (in which
    case NA is used)

  o various documentation updates/fixes; see the
    ChangeLog for all details.

v0.10-0  (2018-10-19)

  o btest: support automatic computation of
    variations, both serially and in parallel.  See new
    arguments 'variations', 'variations.settings'
    and 'replications'. See some examples at
    http://enricoschumann.net/notes/parallel-backtests.html

  o new generic function 'streaks' with methods for
    zoo, NAVseries and numeric vectors

  o new vignette on 'drawdowns and streaks'

  o pl: In several cases in which profit/loss was set
    to NA, it now defaults (more appropriately) to 0.
    For instance, with a custom timestamp the
    realised/unrealised profit/loss before the first
    trade is now 0, not NA.

  o quote32: the function now also recognises a
    colon (:) as a separator. The function can now parse
    more variations; see examples at
    http://enricoschumann.net/notes/treasury-bond-quotes.html

  o instrument: new replacement method
    `instrument<-.journal`

  o drawdowns: new method for NAVseries

  o valuation.position method is now exported (though
    still experimental)

  o pl.btest: fixed passing of additional arguments

  o returns: argument 'period' may also be 'hourly'

  o scale1: argument 'when' may also be 'last'

  o various documentation updates/fixes; see the
    ChangeLog for all details. The manual at
    http://enricoschumann.net/R/packages/PMwR/manual/PMwR.html
    has also been updated.

v0.9-0  (2018-06-09)

  o summary.NAVseries: argument 'monthly' has been
    renamed:

        monthly   =>   monthly.vol

  o summary.NAVseries: new argument 'assume.daily',
    with default FALSE; when TRUE, numeric
    timestamps are considered daily data, e.g. for
    annualising returns

  o NAVseries: add a 'window' method

  o NAVseries: summary now includes recovery from
    drawdown

  o journal: add an 'all.equal' method

  o btest: new argument 'include.timestamp', with
    default TRUE

  o returns: for portfolio returns, if a timestamp
    is specified, 'rebalance.when' is matched
    against this timestamp (e.g., 'rebalance.when'
    may be specified as Date when the timestamp is
    of class Date)

v0.8-0  (2018-04-30)

  o drawdowns: new generic function with methods for
    zoo and numeric vectors

  o plot_trading_hours: improved support for daily
    series (interval becomes "1 day", etc.)

  o pl: new argument 'do.sum'; if TRUE, P/L across
    instruments is summed

  o pl: new argument 'pl.only'; if TRUE, return P/L as
    a numeric vector

  o btest: if a timestamp of class Date or POSIXct is
    specified, burnin 'b' may be an actual timestamp

  o rebalance: new argument 'current.weights' with
    default FALSE; if TRUE, the current portfolio is
    assumed to be a vector of weights

  o returns: add method for as.data.frame for
    holding-period returns

  o the manual has been substantially revised. See
    http://enricoschumann.net/R/packages/PMwR/manual/PMwR.html

v0.7-0  (2018-01-01)

  o scale1: objects that are modified by 'scale1' gain
    an attribute "scale1_origin", which provides the
    timestamp at which scaling starts

  o btest: the handling of argument 'lag' has been
    fixed (the argument had been ignored in some
    situations)

  o quote32: the function now also recognises a
    colon (:) as a separator

  o pl: new method for data frames

  o New vignettes: "Computing returns", "Treasury
    Quotes with 1/32 Fractions" and "Profit/Loss for
    Open Positions"

v0.6-0  (2017-11-16)

  o btest: two arguments have been renamed

        tradeOnOpen      =>  trade.at.open
        assignInGlobals  =>  Globals

  o plot_trading_hours: two arguments have been renamed

        excludeWeekends  =>  exclude.weekends
        do.plotAxis      =>  do.plot.axis

  o Function 'isValidISIN' is no longer available; use
    the drop-in replacement 'is_valid_ISIN' instead.

  o Byte-compilation is now on by default.

  o New vignette 'FinTeX'.

  o New datasets DAX and REXP.

  o New generic function instrument, also for
    replacement.

  o NAVseries: new method 'toLatex.summary.NAVseries';
    see the vignette for examples.

  o pricetable: the function is now a generic, with a
    default and a zoo method. Methods for pricetable
    have been added (print, `[`, as.matrix).

  o quote32: the function now recognises both a hyphen
    (-) or single quote (') as a separator

  o A more-comprehensive list of changes is available
    in the ChangeLog:
    http://enricoschumann.net/R/packages/PMwR/ChangeLog

v0.5-0  (2017-06-23)

  o A number of functions have been renamed:

      isValidISIN      => is_valid_ISIN
      closeOnFirst     => close_on_first
      plotTradingHours => plot_trading_hours
      scaleToUnity     => scale_to_unity
      scaleTrades      => scale_trades
      splitTrades      => split_trades
      twExposure       => tw_exposure

    For the time being, the old functions can still be
    called with

      PMwR:::<old-fun-name>

    but the old names shall be removed in a future
    version.

  o New 'as.matrix' method for monthly holding-period
    returns, which places returns into a numeric matrix
    with years in rows and months in columns. For other
    holding periods, as.matrix is called on the raw
    numeric data.

  o returns: argument 'period' may also be 'quarterly'
    or a single year, such as "2007"

  o btest: 'do.signal' and 'do.rebalance' can also be
    the string 'lastofquarter' to rebalance on last day
    of quarter; or 'firstofquarter' to rebalance on
    first day of quarter

  o A more-comprehensive list of changes is available
    in the ChangeLog:
    http://enricoschumann.net/R/packages/PMwR/ChangeLog

v0.4-0  (2017-02-07)

  o New functions 'unit_prices', for computing
    time-weighted returns, and 'rc', for computing
    return contributions.

  o New helper functions '.expand' and '.tree', for
    displaying account hierachies.

  o Various new methods: 'as.data.frame.position',
    'summary.journal', 'as.zoo.position', 'pl.btest',
    'toOrg.journal'.

  o Support for (some) arithmetic operations on
    'position' and 'quote32' objects.

  o Updated manual chapter on computing returns:
    http://enricoschumann.net/R/packages/PMwR/manual/PMwR.html#computing-returns

  o Updated manual chapter on backtesting:
    http://enricoschumann.net/R/packages/PMwR/manual/PMwR.html#backtesting

v0.3-4  (2016-06-13)

  o Moved function 'runStats' to a separate package 'runStats'
    http://enricoschumann.net/R/packages/runStats/ .
    The PMwR package contains only R code now, so no
    special tools are required for installing from source.

  o There is a public Git repository at
    https://github.com/enricoschumann/PMwR

v0.1-96  (2016-03-13)

v0.1-90  (2016-02-25)

  o A draft of the manual chapter on scaling series is
    available:
    http://enricoschumann.net/R/packages/PMwR/manual/PMwR.html#scaling-series

    profit-and-loss and returns, reporting, and more.
    The package is still under heavy development.
    Please see the ChangeLog for updates.
