Subject: [PATCH 1/2] Inject plotly.js into the output cell on every
 `init_notebook_mode` call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #458

Running init_notebook_mode injects plotly.js into the output cell.
Before, if you ran it twice, it would clear the output cell on the
second call and remove plotly.js from DOM.
This was deceiving, because any existing plots on the page wouldn’t
disappear even though their underlying plotly.js was no longer present.
But, if you refresh the page, the plots would not render (as plotly.js
was no longer in the output cell)

 ## [Unreleased]
 
+## [1.10.0] - 2016-05-19
+### Fixed
+Version 1.9.13 fixed an issue in offline mode where if you ran `init_notebook_mode`
+more than once the function would skip importing (because it saw that it had
+already imported the library) but then accidentally clear plotly.js from the DOM.
+This meant that if you ran `init_notebook_mode` more than once, your graphs would
+not appear when you refreshed the page.
+Version 1.9.13 solved this issue by injecting plotly.js with every iplot call.
+While this works, it also injects the library excessively, causing notebooks
+to have multiple versions of plotly.js inline in the DOM, potentially making
+notebooks with many `iplot` calls very large.
+Version 1.10.0 brings back the requirement to call `init_notebook_mode` before
+making an `iplot` call. It makes `init_notebook_mode` idempotent: you can call
+it multiple times without worrying about losing your plots on refresh.
+
+
+## [1.9.13] - 2016-05-19
+### Fixed
+- Fixed issue in offline mode related to the inability to reload plotly.js on page refresh and extra init_notebook_mode calls.
+
 ## [1.9.12] - 2016-05-16
 ### Added
 SSL support for streaming.
