+Announcement for Dynare 4.2.4 (on 2011-12-02)
+=============================================
+
+We are pleased to announce the release of Dynare 4.2.4.
+
+This is a bugfix release. It comes only a few days after the previous release,
+because version 4.2.3 was affected by a critical bug (see below).
+
+The Windows package for the new release is already available for download at
+the official Dynare website <http://www.dynare.org>. The Mac and Linux packages
+should follow soon.
+
+All users are strongly encouraged to upgrade, especially those who have
+installed the buggy 4.2.3 release.
+
+The new release is compatible with MATLAB versions ranging from 7.0 (R14) to
+7.13 (R2011b) and with GNU Octave versions ranging from 3.0 to 3.4.
+
+Here is the list of the problems identified in version 4.2.3 and that have been
+fixed in version 4.2.4:
+
+ * Second order approximation was broken for most models, giving incorrect
+   results (this problem only affects version 4.2.3, not previous versions)
+
+ * Bayesian priors with inverse gamma distribution and very small variances
+   were giving incorrect results in some cases
+
+ * The `model_diagnostics' command was broken
