 web_components, and template_binding) if they impact polymer.
 
-#### Pub version 0.12.1-dev
+#### Pub version 0.12.1
+  * **New**: When running in pub-serve, any warnings and errors detected by the
+    polymer transformers will be displayed in the lower-right corner of your
+    entrypoint page. You can opt-out by adding this option to your pubspec:
+
+        transformers:
+        - polymer:
+            ...
+            inject_build_logs_in_output: false
+
+  * **New**: there are now two template generators in the polymer package! On
+    any project that depends on polymer, you can create template files for a new
+    custom element by invoking:
+
+        pub run polymer:new_element element-name [-o output_dir]
+
+    And, if you invoke:
+
+        pub run polymer:new_entry web/index.html
+
+    we will create a new entry-point file and add it to your pubspec for you.
+
   * Added the ability to override the stylesheet inlining behavior. There is now
     an option exposed in the pubspec.yaml called `inline_stylesheets`. There are
     two possible values, a boolean or a map. If only a boolean is supplied then

+                packages/foo/bar.css: true
 
-  * Added `inject_build_logs_in_output` option to pubspec for polymer
-    transformers. When set to `true`, this will inject a small element into your
-    entry point pages that will display all log messages from the polymer
-    transformers during the build step. This element is only injected when not 
-    running in release mode (ie: `pub serve` but not `pub build`).
+    
+  * Bug fix for http://dartbug.com/20286. Bindings in url attributes will no
+    longer throw an error.

 #### Pub version 0.12.0+7
   * Widen the constraint on `unittest`.

+# The nossl file below help work around bugs/features in interaction between
+# AppEngine and AppCache. When a return user goes to http://try.dartlang.org/
+# (no SSL), AppCache will serve index.html from cache, try to fetch the old
+# manifest (nossl.appcache) and the files listed in the manifest. In additation
+# the files listed in the manifest, it will also fetch index.html, as it is the
+# master. However, we want index.html to be redirected to the SSL version, and
+# AppCache sees this redirection as a network error. When an error occurs,
+# AppCache will keep serving the old page. So we configure nossl.appcache to
+# provide fallbacks for index.html and leap.dart.js. The fallback for
+# leap.dart.js is nossl.js which will take care of redirecting to
+# https://try.dartlang.org/ (with SSL) using JavaScript.  Unfortunately, Chrome
+# seems to keep the old version of index.html cached indefinitely. The only way
+# to avoid that appears to serve up a different index.html depending on if it
+# is a secure connection or not. This would require a Python script, and
+# something we may consider implementing in the future.
