+Version 4.1b1 pre-release --- 2016-01-10
+----------------------------------------
+
+- Branch analysis has been rewritten: it used to be based on bytecode, but now
+  uses AST analysis.  This has changed a number of things:
+
+  - More code paths are now considered runnable, especially in `try`/`except`
+    structures.  This may mean that coverage.py will identify more code paths
+    as uncovered.  This could either raise or lower your overall coverage
+    number.
+
+  - Python 3.5's `async` and `await` keywords are properly supported, fixing
+    `issue 434`_.
+
+  - A some long-standing branch coverage bugs were fixed:
+
+    - `issue 129`_: functions with only a docstring for a body would incorrectly
+      report a missing branch on the ``def`` line.
+
+    - `issue 212`_: code in an ``except`` block could be incorrectly marked as
+      a missing branch.
+
+    - `issue 146`_: context managers (``with`` statements) in a loop or ``try``
+      block could confuse the branch measurement, reporting incorrect partial
+      branches.
+
+    - `issue 422`_: in Python 3.5, an actual partial branch could be marked as
+      complete.
+
+- Pragmas to disable coverage measurement can now be used on decorator lines,
+  and they will apply to the entire function or class being decorated.  This
+  implements the feature requested in `issue 131`_.
+
+- Multiprocessing support is now available on Windows.  Thanks, Rodrigue
+  Cloutier.
