Each entry below describes changes since the previous version.

Par 1.00 released 25 July 1993
    The first release.

Par 1.10 released 2 August 1993
    Fixed the following bugs:
        In reformat.c I used sprintf() but forgot to #include <stdio.h>.
        I forgot to verify that <width> > <prefix> + <suffix>.
        The first word of a paragraph was expanded to include initial white
        characters, not just spaces, contrary to par.doc.
        Some invalid options were not complained about.
        NUL characters in the input were not handled.
        A pointer foul-up in freelines() in par.c could cause a crash.
    Added the following features:
        The f, j, and t options.
        The PARBODY environment variable.
        Multiple options may be concatenated into a single argument.
    Removed the m option:
        Its function is better performed by the f and t options.  Normally
        I would avoid making incompatible changes, unless I were doing a
        complete overhaul of the whole program, in which case I'd make the
        version number 2.00 to alert users to possible incompatibilities.
        However, in this particular instance I allowed an incompatibility in
        a minor upgrade because version 1.00 was distributed to only four
        people.
    Changed the handling of white characters:
        par now changes all of them (except newlines) to spaces as they are
        read.  This is another incompatible change, excused for the same
        reason.
    Made all error messages begin with "par error:".

Par 1.20 released 10 August 1993
    Since Par 1.10 was distributed to no one, I've made some more
        incompatible changes in Par 1.20.
    Added the following features:
        The d option.
        Paragraphs are now separated by vacant lines, not just blank lines.
        <hang> now affects not only <prefix> but also <suffix>.

Par 1.30 released 18 August 1993
    Since Par 1.20 was posted to comp.sources.misc, I have made only
        backward-compatible changes in Par 1.30.
    Fixed the following bugs:
        One wrong word in par.c sometimes caused par to crash.  Thanks go to
            [e-mail] (Contr Karl Vogel) for sending me
            an input file that caused a crash.
        Too-long words were chopped up before the first word in a paragraph
            was expanded to include initial spaces, allowing impossibility
            #1 to occur.  The order of the two operations has been reversed.
            Thanks go to [e-mail] (Andrew Cashin) for reporting
            the error message.
    Added the following features:
        The g option (motivated by suggestions from several people).
        The q option (inspired by a suggestion from [e-mail]
            (Andrew Cashin)).
        The R option (my attempt to squash a bad idea from Par 1.00).
        The PARQUOTE environment variable (comes with the q option).
        The PARPROTECT environment variable (inspired by a suggestion from
            [e-mail] (Dennis Flaherty)).
    Altered the terminology:
        Several terms have been added, and the meaning of some terms has
        been slightly modified.  This is a change in the language used to
        describe par's behavior, not a change in par's actual behavior.
    Added a clean target to protoMakefile (suggested by [e-mail] (Hal
        Jespersen)).

Par 1.31 released 7 September 1993
    The version number is 1.31 rather than 1.40 because all added features
        are really just enhancements of existing features.
    Fixed the following bug:
        In par.doc, in the example of a paragraph produced by a greedy
            algorithm, the word "establish" appeared twice in a row.  Thanks
            go to [e-mail] (Daniel Kussendrager) for first
            pointing this out.  (The example is now even better because the
            paragraph looks even worse than before.)
    Added the following features:
        A usage message to accompany command line or environment variable
            syntax errors (first suggested by [e-mail] (Karl
            Stiefvater)).
        The help and c options.
        The B, P, and Q options, which render PARBODY, PARPROTECT, and
            PARQUOTE no longer necessary.  They are retained, though, for
            compatibility and convenience.
        The _b, _q, and _Q escape sequences for charset syntax.
    Added the term "charset syntax".
    Isolated the character set code in charset.c and charset.h.

Par 1.32 released 13 September 1993
    Fixed the following bugs:
        par could crash when the + or - operator was used with the B, P, and
            Q options.  Thanks go to [e-mail] (Andrew Cashin) for
            reporting this.
        If <quote> were 1 and two adjacent lines had different
            quoteprefixes, one of which was a prefix of the other, and only
            the line with the shorter quoteprefix contained a non-quote
            character, then nothing would be altered.  According to
            par.doc 1.31, this was correct, but since neither line is
            vacant, I consider this a bug in the design of the <quote>
            feature.  Now the longer quoteprefix will be truncated to match
            the shorter one, and will therefore be vacant.  Thanks go to
            [e-mail] (Andrew Cashin) for asking about this.
    Made slight changes to the documentation.

Par 1.40 released 10 Oct 1993
    Fixed the following bugs:
        The phrase "containing at least two lines" was left out of the
            definition of "vacant line" in par.doc and par.1, although
            the code implemented the correct definition.  (The phrase now
            appears in the definition of "order <k> bodiless line".)
        There was still a flaw in the design of the <quote> feature.  If two
            adjacent lines had quoteprefixes neither of which was a prefix
            of the other, no line would be inserted between them, possibly
            causing other inserted lines not to be vacant.  Now it should
            be true that every line inserted or truncated by the <quote>
            feature will turn out to be vacant.
        When <hang> began affecting the default value of <suffix> (as of Par
            1.20), it should also have begun affecting the choice of source
            of characters for the suffixes of lines in OPs.
    Added the following features:
        The i option (suggested by [e-mail] (Alan Barrett)).
        The e option (inspired by a suggestion from [e-mail]
            (Tim Pointing)).
        The r option.
        The p, s, and w options are now accepted without numbers.
        par no longer gives up so easily when choosing default values for
            <prefix> and <suffix> for an IP with less than <hang>+2 lines,
            nor when choosing the source of characters for the prefix and
            suffix of the <i>th output line when <i> > <n> and <n> <=
            <hang>.  These are incompatible changes, but I cannot imagine
            anyone preferring the old behavior.
    Altered the terminology:
        Added the terms "bodiless line" (a generalization of "vacant line"),
            "fallback prelen", and "fallback suflen".
    Made miscellaneous changes to the documentation, including the addition
        of the Quick Start section.

Par 1.41 released 31 Oct 1993
    Moved the former Release Notes section of par.doc into its own file.
    Fixed the following bugs:
        A couple of inconsistencies of style in the code (pointed out by
            [e-mail] (Thomas E. Dickey).
        If <quote> and <hang> were 1 and a one-line paragraph beginning with
            quote characters was reformatted into a multi-line paragraph,
            the new lines began with spaces instead of quote characters.
            This was because the policy for copying prefixes used the
            fallback prelen rather than the augmented version of it used
            for computing the default value of <prefix>.  Now both use the
            same formula.  Thanks go to [e-mail] (Steven King) for
            reporting the problem.
        If the t option were given without a number, it was unset instead of
            being set to 1.
    Added the following feature:
        The E option (suggested by [e-mail] (Alex Matulich)).
    Altered the terminology:
        Added the term "augmented fallback prelen".
    Added to the Rights and Responsibilities section of par.doc a guideline
        for handling version numbers in patched versions of Par.
    Added a useful suggestion to protoMakefile.

Par 1.50 released 11 Feb 1996
    Added the following features:
        The T option (suggested by [e-mail] (Jules Junker)).
        The b option.
    Loosened the terms of the Copyright.
    Changed protoMakefile:
        Added the E and O macros (suggested by [e-mail]
            (Peter A. Getterman).
        Added sensible default values for all macros.
    Added question-mark to the recommended set of body characters.
    Restored documentation of the number-without-a-letter shortcut
        command-line option, which got lost between versions 1.00 and
        1.10.  Its absence was noted by [e-mail] (David W.
        Sanderson).
    Added .exrc examples (suggested by [e-mail]
        (Alex Matulich), though I used my own .exrc).
    Added the Apologies section to par.doc and par.1.
    Made many other tweeks to the documentation.
    Removed the useless synopsis from the runtime help message.
