    Mistakenly path to @file{.do} file was not absolute and OS can

@anchor{Release 2_0_0}
@section Release 2.0.0
@itemize
@item
    Huge quantity of performance optimisations.

@item
    Fixed possible unexpected lock file closing.

@item
    When resulting target has the same contents, it does not replace
    already existing one. That was done previously. But now it also
    copies the file's mode flags to the target (for example making it
    executable).

@item
    If @command{redo-*} command runs under control of another
    (top-level) redo, then it does not parse the flags as options and
    treat each argument as a target, allowing passing the targets with
    dashes in the beginning.

@item
    Prevented possible concurrent stderr writing by multiple running targets.

@item
    @command{redo-depfix} command now always rewrites dependency files
    and calculates checksums of the files.

@item
    Own binary format is used for dependency files (@file{.dep}),
    instead of recfile (@file{.rec}) one. It is several times smaller
    and much faster to parse. You must run @command{redo-depfix} to
    convert all existing @file{.redo/*.rec} files to that binary format.

@item
    @command{redo-dep2rec} command appeared, that can convert
    @file{.dep} to recfile on stdout.

@anchor{Release 1_28_0}
@section Release 1.28.0
@itemize
@item
    Do not remove @file{.lock} files, that leads to possible races

@anchor{Release 1_25_0}
@section Release 1.25.0
@itemize
@item
    Target's lock file requires a token from the jobserver now. So
    amount of simultaneously opened lock files depends on job slots
    available.

@anchor{Release 1_23_0}
@section Release 1.23.0
@itemize
@item
    @command{redo-ifchange}'s @option{-f} option forces each target
    rebuilding. Comparing to @command{redo}, it will parallelize the
    process.
@item
    Inode's number is also stored as dependency information, just to
    prevent possible @code{ctime} collision of two files.
@item
    Performance optimization: do not use target's temporary output file
    at all, if its hash equals to already existing target's one. Just
    touch existing target file instead.
@end itemize

@anchor{Release 1_22_0}
@section Release 1.22.0
@itemize
@item
    @code{flock} locks replaced with POSIX @code{fcntl} ones.
    They could be more portable.
@item
    @command{redo-depfix} command appeared, that traverses through all
    @file{.redo} directories and their dependency files, checks if
    corresponding targets has the same content but different
    @code{ctime}/@code{mtime} values and rewrites dependencies with that
    updated inode information.
@item
    With @env{$REDO_STOP_IF_MODIFIED=1} environment variable redo will
    stop and fail if it meet externally modified file. By default user
    is only warned about it, but building continues for convenience.

@section Release 1.21.0
@itemize
@item
    @env{$REDO_INODE_NO_TRUST} is replaced with @env{$REDO_INODE_TRUST}
    environment variable, that takes either @code{none}, or @code{ctime}
    (the default one), or @code{mtime} (new one). Check documentation's
    separate page about that option.

    directory, command line arguments, start/finish times, duration,
    participated PIDs, return codes are saved in corresponding

    @option{-c} option to @command{redo-log}.
