        <title>Vertical spacing</title>

        <description>This is a mundane revision where I've normalized the vertical space separators between text sections.  Like the last release, this one won't build for LaTeX without a coqdoc patch that may not be in Coq's Subversion repos yet.  This is the home stretch; I am going to make a proofreading pass through everything, and then I'll be looking for other proofreaders to help come up with the final version to be published by MIT Press!</description>

        <title>Taking advantage of coqdoc changes</title>

        <description>Starting with some help from Matthieu Sozeau, a number of improvements have been made to the coqdoc program, which is used to generate CPDT renderings.  The changes aren't in any Coq release yet (not even an 8.4 beta release), but I hope they will make it into the final 8.4, and I've used a working Coq version to generate pretty outputs.  Now the only concrete change I have planned before the final CPDT version for publication is tweaking of empty vertical space between some page elements.</description>

        <description>I'm getting ready for the final push to get the PDF rendering into shape to use as the final version of the book to deliver to MIT Press.  I plan to get some coqdoc issues fixed, and I've undone some hack-arounds that were meant to avoid a need for coqdoc changes, in addition to some general improvements to the markup.  I've also made some changes to take advantage of Coq 8.4 features.</description>

        <title>New chapter: "A Taste of Reasoning About Programming Language Syntax"</title>

        <description>This new chapter condenses and recasts some material from the old Part IV of CPDT.  I felt the level of detail I was giving was out of proportion to my certainty that the techniques I was demonstrating would make sense to use in 5 years, so I'm opting instead for a quick tour that is mostly meant to convey the moral that encoding choices matter (but also to introduce PHOAS).</description>

        <title>Two new tricks useful in proof by reflection</title>

        <author>adamc@csail.mit.edu</author>
        <description>The "Universes and Axioms" chapter has a new ending describing a way to avoid axioms in dealing with reified typing environments, and the "Proof by Reflection" chapter has a new ending explaining how to write a reification function that recurses under binders.</description>

        <description>I've moved the exercises out of the book, because I don't feel that I have the time to produce well-tested exercises yet; changed crush's use of autorewrite so that Hint Rewrite commands may be given without explicit hint databases; added a crucial new section to "More Dependent Types"; and added prose and other improvements to "Proof Search by Logic Programming."</description>

	<description>I've started passes through all chapters, with an eye toward getting ready both for <a href="http://stellar.mit.edu/S/course/6/fa11/6.892/">my fall class</a> and publication by MIT Press.  I'm adding bibliographic references, index entries, and additional exercises, along with the usual tweaks and improvements.  The version I've just put up is the result of a pass through Chapter 1.  Feedback is especially welcome now, as I get the book into final publishable shape!</description>
