v2.2.2

• Fixed a bug introduced in v2.2 that prevented setting the Pygments style in
  the preamble. Style definitions are now more compatible with using
  \MintedPygmentize to call a custom pygmentize.

v2.2.1

• The shellesc package is loaded before ifplatform and other packages
  that might invoke \write18 (#112).
• When caching is enabled, XeTeX uses the new \mdfivesum macro from TeX
  Live 2016 to hash cache content, rather than using \ShellEscape with
  Python to perform hashing.

v2.2

• All uses of \ShellEscape (\write18) no longer wrap file names and paths
  with double quotes. This allows a cache directory to be specified relative
  to a user's home directory, for example, ~/minted_cache. cachedir and
  outputdir paths containing spaces will now require explicit quoting of
  the parts of the paths that contain spaces, since minted no longer
  supplies quoting. See the updated documentation for examples (#89).
• Added breakbefore, breakbeforegroup, breakbeforesymbolpre, and
  breakbeforesymbolpost. These parallel breakafter*. It is possible to
  use breakbefore and breakafter for the same character, so long as
  breakbeforegroup and breakaftergroup have the same setting (#117).
• Added package options finalizecache and frozencache. These allow the
  cache to be prepared for (finalizecache) and then used (frozencache) in
  an environment in which -shell-escape, Python, and/or Pygments are not
  available. Note that this only works if minted content does not need to
  be modified, and if no settings that depend on Pygments or Python need to
  be changed (#113).
• Style names containing hyphens and underscores (paraiso-light,
  paraiso-dark, algol_nu) now work (#111).
• The shellesc package is now loaded, when available, for compatibility
  with luatex 0.87+ (TeX Live 2016+, etc.). \ShellEscape is now used
  everywhere instead of \immediate\write18. If shellesc is not available,
  then a \ShellEscape macro is created. When shellesc is loaded, there
  is a check for versions before v0.01c to patch a bug in v0.01b (present in
  TeX Live 2015) (#112).
• The bgcolor option now uses the snugshade* environment from the framed
  package, so bgcolor is now compatible with page breaks. When bgcolor
  is in use, immediately preceding text will no longer push the minted
  environment into the margin, and there is now adequate spacing from
  surrounding text (#121).
• Added missing support for fancyvrb's labelposition (#102).
• Improved fix for TikZ externalization, thanks to Patrick Vogt (#73).
• Fixed breakautoindent; it was disabled in version 2.1 due to a bug in
  breakanywhere.
• Properly fixed handling of \MintedPygmentize (#62).
• Added note on incompatibility of breaklines and obeytabs options.
  Trying to use these together will now result in a package error (#99).
  Added note on issues with obeytabs and multiline comments (#88). Due to
  the various obeytabs issues, the docs now discourage using obeytabs.
• Added note to FAQ on fancybox and fancyvrb conflict (#87).
• Added note to docs on the need for \VerbatimEnvironment in environment
  definitions based on minted environments.

v2.1

• Changing the highlighting style now no longer involves re-highlighing
  code. Style may be changed with almost no overhead.
• Improved control of automatic line breaks. New option breakanywhere
  allows line breaks anywhere when breaklines=true. The pre-break and
  post-break symbols for these types of breaks may be set with
  breakanywheresymbolpre and breakanywheresymbolpost (#79). New option
  breakafter allows specifying characters after which line breaks are
  allowed. Breaks between adjacent, identical characters may be controlled
  with breakaftergroup. The pre-break and post-break symbols for these
  types of breaks may be set with breakaftersymbolpre and
  breakaftersymbolpost.
• breakbytoken now only breaks lines between tokens that are separated by
  spaces, matching the documentation. The new option breakbytokenanywhere
  allows for breaking between tokens that are immediately adjacent. Fixed a
  bug in \mintinline that produced a following linebreak when
  \mintinline was the first thing in a paragraph and breakbytoken was
  true (#77).
• Fixed a bug in draft mode option handling for \inputminted (#75).
• Fixed a bug with \MintedPygmentize when a custom pygmentize was
  specified and there was no pygmentize on the default path (#62).
• Added note to docs on caching large numbers of code blocks under OS X (#78).
• Added discussion of current limitations of texcomments (#66) and
  escapeinside (#70).
• PGF/Ti_k_Z externalization is automatically detected and supported
  (#73).
• The package is now compatible with LaTeX files whose names contain spaces (#85).

v2.0

• Added the compatibility package minted1, which provides the minted 1.7 code.
  This may be loaded when 1.7 compatibility is required. This package works with
  other packages that \RequirePackage{minted}, so long as it is loaded first.
• Moved all old \changes into changelog.
• Caching is now on by default.
• Fixed a bug that prevented compiling under Windows when file names
  contained commas.
• Added breaksymbolleft, breaksymbolsepleft,
  breaksymbolindentleft, breaksymbolright, breaksymbolsepright,
  and breaksymbolindentright options. breaksymbol,
  breaksymbolsep, and breaksymbolindent are now aliases for the
  correspondent *left options.
• Added kpsewhich package option. This uses kpsewhich to locate
  the files that are to be highlighted. This provides compatibility
  with build tools like texi2pdf that function by modifying
  TEXINPUTS (#25).
• Fixed a bug that prevented \inputminted from working with outputdir.
• Added informative error messages when Pygments output is missing.
• Added final package option (opposite of draft).
• Renamed the default cache directory to _minted-<jobname> (replaced
  leading period with underscore). The leading period caused the cache
  directory to be hidden on many systems, which was a potential source
  of confusion.
• breaklines and breakbytoken now work with \mintinline (#31).
• bgcolor may now be set through \setminted and \setmintedinline.
• When math is enabled via texcomments, mathescape, or
  escapeinside, space characters now behave as in normal math by
  vanishing, instead of appearing as literal spaces. Math need no
  longer be specially formatted to avoid undesired spaces.
• In default value of \listoflistingscaption, capitalized “Listings” so that
  capitalization is consistent with default values for other lists
  (figures, tables, algorithms, etc.).
• Added newfloat package option that creates the listing
  environment using newfloat rather than float, thus providing
  better compatibility with the caption package (#12).
• Added support for Pygments option stripall.
• Added breakbytoken option that prevents breaklines from breaking
  lines within Pygments tokens.
• \mintinline uses a \colorbox when bgcolor is set, to give more
  reasonable behavior (#57).
• For PHP, \mintinline automatically begins with startinline=true (#23).
• Fixed a bug that threw off line numbering in minted when
  langlinenos=false and firstnumber=last. Fixed a bug in \mintinline that
  threw off subsequent line numbering when langlinenos=false and
  firstnumber=last.
• Improved behavior of \mint and \mintinline in draft mode.
• The \mint command now has the additional capability to take code
  delimited by paired curly braces {}.
• It is now possible to set options only for \mintinline using the new
  \setmintedinline command. Inline options override options specified via
  \setminted.
• Completely rewrote option handling. fancyvrb options are now handled on the
  LaTeX side directly, rather than being passed to Pygments and then
  returned. This makes caching more efficient, since code is no longer
  rehighlighted just because options changed.
• Fixed buffer size error caused by using cache with a very large
  number of files (#61).
• Fixed autogobble bug that caused failure under some operating
  systems.
• Added support for escapeinside (requires Pygments 2.0+; #38).
• Fixed issues with XeTeX and caching (#40).
• The upquote package now works correctly with single quotes when
  using Pygments 1.6+ (#34).
• Fixed caching incompatibility with Linux and OS X under xelatex
  (#18 and #42).
• Fixed autogobble incompatibility with Linux and OS X.
• \mintinline and derived commands are now robust, via \newrobustcmd
  from etoolbox.
• Unused styles are now cleaned up when caching.
• Fixed a bug that could interfere with caching (#24).
• Added draft package option (#39). This typesets all code using
  fancyvrb; Pygments is not used. This trades syntax highlighting
  for maximum speed in compiling.
• Added automatic line breaking with breaklines and related options
  (#1).
• Fixed a bug with boolean options that needed a False argument to
  cooperate with \setminted (#48).

v2.0-alpha3

v2.0-alpha3 (2013/12/21)

• Added autogobble option. This sends code through Python's
  textwrap.dedent() to remove common leading whitespace.
• Added package option cachedir. This allows the directory in which
  cached content is saved to be specified.
• Added package option outputdir. This allows an output directory for
  temporary files to be specified, so that the package can work with
  LaTeX's -output-directory command-line option.
• The kvoptions package is now required. It is needed to process
  key-value package options, such as the new cachedir option.
• Many small improvements, including better handling of paths under
  Windows and improved key system.

v2.0-alpha2

v2.0-alpha2 (2013/08/21)

• \DeleteFile now only deletes files if they do indeed exist. This eliminates warning messages due to missing files.
• Fixed a bug in the definition of \DeleteFile for non-Windows systems.
• Added support for Pygments option stripnl.
• Settings macros that were previously defined globally are now defined locally, so that \setminted may be confined by \begingroup...\endgroup as expected.
• Macro definitions for a given style are now loaded only once per document, rather than once per command/environment. This works even without caching.
• A custom script/executable may now be substituted for pygmentize by redefining \MintedPygmentize.
