+2.1-193 | 2012-12-03 14:11:14 -0800
+
+  * Fix a set of bugs with table/set attributes. (Jon Siwek)
+
+    - Identifiers that are initialized with set()/table() constructor
+      expressions now inherit attributes from the expression.  Before,
+      statements like
+
+         const i: set[string] = set() &redef;
+
+      associated the attribute with the set() constructor, but not the
+      "i" identifier, preventing redefinition.  Addresses #866.
+
+    - Allow &default attribute to apply to tables initialized as empty
+      (via either "{ }" or "table()") or if the expression supplied to it
+      can evaluate to a type that's promotable to the same yield type as
+      the table.
+
+2.1-191 | 2012-12-03 14:08:56 -0800
+
+  * Add test of record() constructor to table initializer unit test.
+    (Jon Siwek)
+
+  * Fix table(), set(), vector() constructors in table initializer
+    lists. Also adds type checking of yield values to table()
+    constructor and fixes the type checking of yield values in
+    vector() constructor. Addresses #5. (Jon Siwek)
+
+2.1-188 | 2012-12-03 14:04:29 -0800
+
+  * Hook functions now callable with "hook" expression (i.e., hook is
+    no longer a statement). The return value of the call is an
+    implicit boolean value of T if all hook handlers ran, or F if one
+    hook handler exited as a result of a break statement and
+    potentially prevented other handlers from running.
+
+    Scripts don't need to declare hooks with an explicit return type of bool
+    (internally, that's assumed), and any values given to (optional) return
+    statements in handler definitions are just ignored.
+
+    Addresses #918. (Jon Siwek)
+
+  * Clarification in hook documentation. (Jon Siwek)
+
+2.1-184 | 2012-12-03 13:59:50 -0800
+
+  * Slightly fix up file name extraction from Content-Disposition
+    headers. (Seth Hall)
+
+  * Adding -b flag to bro in unit tests so they run faster.
+
+  * Fixed a DNS attribute issue. Reported by Matt Thompson. (Seth
+    Hall)
+
+  * Adding NEWS placeholder for hooks and CSV mode. (Robin Sommer)
