+                Release Notes for cloc version 1.68
+                   https://github.com/AlDanial/cloc
+                             June 3, 2016
+
+New Languages:
+    o Blade
+    o Brainfuck
+    o builder
+    o Clean
+    o INI
+    o JSX
+    o liquid
+    o Logtalk
+    o Markdown
+    o Mathematica
+    o Pug
+    o Qt Linguist
+    o Slim
+    o TTCN
+
+Updates:
+    o --help output now goes to STDOUT instead of STDERR.
+    o Shortened cloc's output header line by removing "https:" from the
+      github repository URL.
+    o Add block comment support to CoffeeScript.
+    o Improve Coq/Verilog disambiguator by recognizing more Coq keywords.
+    o Improve handling of HAML block comments.
+    o Improve Pascal/Puppet disambiguator.
+    o Improve Perl/Prolog disambiguator by recognizing Perl HERE documents.
+    o Add .cuh extension for CUDA.
+    o Add .hxx extension for C/C++ header files.
+    o Associate .mk extension with make.
+
+New options and features:
+
+    --use-sloccount           If SLOCCount is installed, use its compiled
+                              executables c_count, java_count, pascal_count,
+                              php_count, and xml_count instead of cloc's
+                              counters.  SLOCCount's compiled counters are
+                              substantially faster than cloc's and may give
+                              a performance improvement when counting projects
+                              with large files.  However, these cloc-specific
+                              features will not be available: --diff,
+                              --count-and-diff, --strip-comments, --unicode.
+     --vcs=<VCS>              Invoke a system call to <VCS> to obtain a list of
+                              files to work on.  If <VCS> is 'git', then will
+                              invoke 'git ls-files'.  If <VCS> is 'svn' then
+                              will invoke 'svn list -R'.  The primary benefit
+                              is that cloc will then skip files explicitly
+                              excluded by the versioning tool in question,
+                              ie, those in .gitignore or have the svn:ignore
+                              property.
+                              Alternatively <VCS> may be any system command
+                              that generates a list of files.
+                              Note:  cloc must be in a directory which can read
+                              the files as they are returned by <VCS>.  cloc
+                              will not download files from remote repositories.
+                              'svn list -R' may refer to a remote repository
+                              to obtain file names (and therefore may require
+                              authentication to the remote repository), but
+                              the files themselves must be local.
+
+
+    o Handle .deb archive files on Unix-like operating systems that have
+      the Debian 'dpkg-deb' command.  This is only useful for counting
+      lines in Debian packages that contain source code--most contain
+      only compiled executables.
+
+Bug Fixes:
+    o Updated documentation for --exclude-dir to prohibit path separators.
+    o Correct file path normalization problem when directory contains
+      trailing slash.
+    o --list-file:  Return an empty list if the file cannot be read.
+    o --exclude-dir:  correctly handle command line input consisting of a 
+      file with leading directory names, eg abc/def/hello.c, by first
+      checking that parent directories aren't in exclusion list.
+    o Expand behavior of --fullpath to also work with --not-match-d.
+    o Split into two statements expressions like "scalar(split(..))"
+      which are deprecated in Perl 5.22.
+    o --sum-reports: Give a useful error message when encountering an unknown 
+      language during report summation.
