0.2.1:

  * Changed: title formatting.


0.2:

  * Fixed: corrected the leading order in the asymptotics for \rho_1 in
           theorem 1.2.

  * Fixed: The clusters in the cluster expansion are multi-sets, not sets.

  * Fixed: The Ursell function in lemma 3.3 needs to be divided by the
           multiplicity of each element.

  * Fixed: In the proofs of lemma 3.4 and theorem 1.2, when individuating a
           polymer from a cluster, one needs to sum over its multiplicity so
           as to avoid overcounting.

  * Fixed: Wrong estimate in the proof of lemma 3.4 which changes some of the
           constants.

  * Fixed: Missing a smallness condition on \alpha in the proof of lemma 3.4.

  * Fixed: Wrong argument for the analyticity of \zeta in the proof of
           theorem 1.2.

  * Fixed: miscellaneous minor tweaks, reformulations, clarifications and
           typos.

  * Fixed: deleted erroneous reference to Kramers and Wannier.

  * Fixed: changed boundary conditions.

  * Fixed: definition of \mathbb S(X).

  * Fixed: miscellaneous minor tweaks, formatting and typos.
