    `Attrs` objects (for example, stream filters and generators).
  * Python code blocks are now supported using the `<?python ?>` processing
    instruction (ticket #84).
- * Runtime error handling in template expressions has become more strict
-   (ticket #88). Where you previously could access undefined variables or
-   members, you now get an exception. If a variable is not necessarily defined
-   at the top level of the template data, the new built-in functions
-   `defined(name)` and `value_of(name, default)` need to be used.
+ * The way errors in template expressions are handled can now be configured. The
+   option `LenientLookup` provides the same forgiving mode used in previous
+   Genshi versions, while `StrictLookup` raises exceptions when undefined
+   variables or members are accessed. The lenient mode is still the default in
+   this version, but that may change in the future. (ticket #88)
+ * If a variable is not necessarily defined at the top level of the template
+   data, the new built-in functions `defined(key)` and `value_of(key, default)`
+   can be used so that the template also works in strict lookup mode. These
+   functions were previously only available when using Genshi via the template
+   engine plugin (for compatibility with Kid).
  * `style` attributes are no longer allowed by the `HTMLSanitizer` by default.
    If it is explicitly added to the set of safe attributes, and unicode escapes
    in the attribute value are handled correctly.
