+## Custom Patches
+
+If you use a custom `HTTPConnection` class, or otherwise make http
+requests in a way that requires additional patching, you can use the
+`custom_patches` keyword argument of the `VCR` and `Cassette` objects
+to patch those objects whenever a cassette's context is entered. To
+patch a custom version of `HTTPConnection` you can do something like
+this:
+
+```
+import where_the_custom_https_connection_lives
+from vcr.stubs import VCRHTTPSConnection
+my_vcr = config.VCR(custom_patches=((where_the_custom_https_connection_lives, 'CustomHTTPSConnection', VCRHTTPSConnection),))

 ## Changelog
+  * 1.3.0 Fix/add support for urllib3 (thanks @aisch), fix default
+    port for https (thanks @abhinav).
+  * 1.2.0 Add custom_patches argument to VCR/Cassette objects to allow
+    users to stub custom classes when cassettes become active.
+  * 1.1.4 Add force reset around calls to actual connection from stubs, to ensure
+    compatibility with the version of httplib/urlib2 in python 2.7.9.
   * 1.1.3 Fix python3 headers field (thanks @rtaboada), fix boto test (thanks
     @telaviv), fix new_episodes record mode (thanks @jashugan), fix Windows
