+* File unlocks are atomic again via rename. Read-only files on Windows are
+  made read-write if necessary.
+
+* Share open packfiles across repositories to share descriptors and mmaps.
+
+* Use a map for the treebuilder, making insertion O(1)
+
+* LF -> CRLF filter refuses to handle mixed-EOL files
+
+* LF -> CRLF filter now runs when * text = auto (with Git for Windows 1.9.4)
+
+* The git_transport structure definition has moved into the sys/transport.h
+  file.
+
+* The git_transport_register function no longer takes a priority and takes
+  a URL scheme name (eg "http") instead of a prefix like "http://"
+
+* The git_remote_set_transport function now sets a transport factory function,
+  rather than a pre-existing transport instance.
+
+* A factory function for ssh has been added which allows to change the
+  path of the programs to execute for receive-pack and upload-pack on
+  the server, git_transport_ssh_with_paths.
+
+* The git_clone_options struct no longer provides the ignore_cert_errors or
+  remote_name members for remote customization.
+
+  Instead, the git_clone_options struct has two new members, remote_cb and
+  remote_cb_payload, which allow the caller to completely override the remote
+  creation process. If needed, the caller can use this callback to give their
+  remote a name other than the default (origin) or disable cert checking.
+
+  The remote_callbacks member has been preserved for convenience, although it
+  is not used when a remote creation callback is supplied.
+
+* The git_clone_options struct now provides repository_cb and
+  repository_cb_payload to allow the user to create a repository with
+  custom options.
+
+* git_clone_into and git_clone_local_into have been removed from the
+  public API in favour of git_clone callbacks
+
+* Add support for refspecs with the asterisk in the middle of a
+  pattern.

+   inflateBack() needs more input, it calls in().  When inflateBack() has
+   filled the window with output, or when it completes with data in the
+   window, it calls out() to write out the data.  The application must not

+   inflateBack() returns.
+
+   in() and out() are called with a descriptor parameter provided in the

+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
+   was in() or out() that caused in the error.  Otherwise,  inflateBack()
+   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+   error, or Z_MEM_ERROR if it could not allocate memory for the state.

+   to read, looking for another gzip stream.  Any number of gzip streams may be
+   concatenated in the input file, and will all be decompressed by gzread().
+   If something other than a gzip stream is encountered after a gzip stream,
+   that remaining trailing garbage is ignored (and no error is returned).
+
+     gzread can be used to read a gzip file that is being concurrently written.
+   Upon reaching the end of the input, gzread will return with the available
+   data.  If the error code returned by gzerror is Z_OK or Z_BUF_ERROR, then
+   gzclearerr can be used to clear the end of file indicator in order to permit
+   gzread to be tried again.  Z_OK indicates that a gzip stream was completed
+   on the last gzread.  Z_BUF_ERROR indicates that the input file ended in the
+   middle of a gzip stream.  Note that gzread does not return -1 in the event
+   of an incomplete gzip stream.  This error is deferred until gzclose(), which
+   will return Z_BUF_ERROR if the last gzread ended in the middle of a gzip
+   stream.  Alternatively, gzerror can be used before gzclose to detect this
+   case.
 
      gzread returns the number of uncompressed bytes actually read, less than
    len for end of file, or -1 for error.
