+	* 5.1.3: release
+
+	* Bug fix: fix-qdf was not handling object streams with more than
+	255 objects in them.
+
+	* Handle Microsoft crypt provider initialization properly for case
+	where no keys have been previously created, such as in a fresh
+	Windows installation.
+
+	* Include time.h in QUtil.hh for time_t

+
+	* Detect loops in Pages structure. Thanks to Gynvael Coldwind and
+	Mateusz Jurczyk of the Google Security Team for providing a sample
+	file with this problem.
+
+	* Prevent buffer overrun when converting a password to an
+	encryption key. Thanks to Gynvael Coldwind and Mateusz Jurczyk of
+	the Google Security Team for providing a sample file with this
+	problem.
+
+	* Ensure that arguments to "R" when parsing the file are direct
+	objects before trying to resolve them. This prevents specially
+	crafted files from causing qpdf to crash with a stack overflow.

+
+	* Some broken PDF files lack the required /Type key for /Page and
+	/Pages nodes in the page dictionary. QPDF now uses other methods
+	to figure out what kind of node it is looking at so that it can
+	handle those files. Original reported at
+	https://bugs.launchpad.net/ubuntu/+source/qpdf/+bug/1397413
+
+2014-11-14  Jay Berkenbilt  <ejb@ql.org>
+
+	* Bug fix: QPDFObjectHandle::getPageContents() no longer throws an
+	exception when called on a page that has no /Contents key in its
+	dictionary. This is allowed by the spec, and some software
+	packages generate files like this for pages that are blank in the
+	original.

+Local Windows Testing Procedure
+===============================
+
+This is what I do for routine testing on Windows.
+
+From Linux, run ./autogen.sh and make autofiles.zip

+test with. Run from msys started from one of the visual studio command
+line shells. The build doesn't work from git bash on my local system.

+Small, command-line tool only enhancements to do soon
+=====================================================
+
+ * Handle input file = output file as a special case. See issue 29.
+   Behavior: detect if output file is the same as one of the input
+   files. If so, refuse to operate unless --allow-overwrite is
+   specified. In that case, write to a temporary file and, if there
+   are no errors or warnings, rename the temporary output file over
+   the input file. If rename fails, delete the temporary file.
+
+ * Consider providing alternative methods for specifying passwords.
+   The methods should be general enough to use for both encryption and
+   decryption passwords. Example methods could be reading the password
+   from a file, a file descriptor, or prompting. Prompting should
+   never be done with being specifically requested though; we don't
+   want to create a situation where running qpdf might block waiting
+   for input where it previously did not. Test case: encrypt an
+   encrypted file with the output file having different user/owner
+   passwords. Make sure we have a predictable way to read all three
+   passwords (input, output user, output owner). Maybe we have
+   something like --password-source=<method>:<which>,... where method could
+   be file=/path, fd=n, or prompt and which could be one of input,
+   user, owner. If a password source is provided for input, it takes
+   precedence over --password if specified later on the command line.
+   If a password source is specified for output passwords, the
+   corresponding passwords must be '-'. If more than one password is
+   read from the same source, passwords are newline separated.
+   Trailing newlines are ignored. Example:
+
+   qpdf --password-source=fd=3:input,owner a.pdf b.pdf
+
+   would read two lines from file descriptor 3. The first would the
+   password for reading a.pdf, and the second would be the owner
+   password for b.pdf. The encryption arguments would specify the
+   actual user password for b.pdf and - as the owner password.
+
+   qpdf --password-source=file=/tmp/a:input --password=source=prompt:user,owner
+
+   would read the input file from /tmp/a and would prompt twice: one
+   for the user password and once for the owner password.
+
+ * Consider adding "uninstall" target to makefile. It should only
+   uninstall what it installed, which means that you must run
+   uninstall from the version you ran install with. It would only be
+   supported for the toolchains that support the install target
+   (libtool).

         Bug fix: linearizing files could create a corrupted output
         file under extremely unlikely file size circumstances. See
         ChangeLog for details. The odds of getting hit by this are
