- Fix a bug where the codemirror editor did not show correctly on small screens.
- If an error occurs, give information about whether it happens in the learner's code, or in the creator's prepended/postpended code.
- Change the indent unit to 4.
* GraphInput: Fix #1265: limit the number of vertices in the graph used for isomorphism checks.

v2.1.1 (29 Dec 2015)
--------------------
Learner page:
* Fix #1084: redo the display of recommendations at the end of an exploration.
* When the learner submits feedback, automatically append the current state name to the feedback.
* Fix #714: add an e2e test for exploration ratings.
* Move the help card to the bottom right of the supplemental interaction.
* Do not animate the initial display of an exploration, even if its first state includes a supplemental interaction.
Gallery page:
* In the gallery tiles, show the number of views an exploration has received.
* Unify the backend methods that compute data for the summary tiles.
* Show a badge that indicates if an exploration has recently been updated.
* Fix a bug that caused a backend error to be raised when new-style YAML versions of explorations are uploaded.
* Fix a bug that caused the exploration summary tile data in the gallery to not update correctly when the search query is changed.
* Update the icon used to denote the Mathematics category.
Profile page:
* Fix #1248: correctly display multi-paragraph bios in the Profile page.
* Change heading of statistics tab from 'Statistics' to 'Impact'.
Interactions:
* GraphInput: add a heuristic pre-check for graph isomorphism before performing the full calculation.
* LogicProof: add inline feedback, and improve the handling of tab characters and blank lines.
* For the following interactions, migrate the rule evaluation logic to the frontend: CodeRepl, GraphInput, InteractiveMap, MultipleChoiceInput, PencilCodeEditor and TextInput.
Rich-text components:
* VideoMp4: fix a Chrome bug that caused HTML5 video requests to sometimes forever remain in the 'pending' state.
Editor page:
* Fix #1259: autofocus on the commit message textarea when the Publish Exploration modal is opened.
Other pages:
* Remove the email feature from the moderator page.
Infrastructure:
* Incorporate the string classifier into the backend classification logic.
* Lint all the JavaScript files in the codebase.
* Refactor PlayerServices.js, breaking it down into separate services with distinct responsibilities.
* Create frontend domain objects for Explorations and States.
* Add tests for the third-party manifest file.
* Remove the backend test count.
* Fix #1272: generate minified files before launching the Protractor tests.
* When running the karma tests, do so for both minified and unminified JS files.
Other:
* Add gitter badge to README.md.
v2.1.0 (7 Dec 2015)
-------------------
Learner page:
* Fix #1164: on narrow viewports with supplemental interactions, add buttons to the bottom of both cards to make it easier to navigate to the card that isn't currently showing.
* Fix #1083: prevent the rating form from showing up before the learner has reached the final card of the exploration.
* Fix some errors in the display of the average rating, contributor list, and last-updated time in the exploration information card.
* Make the 'blackboard' background file size much smaller, in order to reduce loading times.
* Fix a bug that caused the window to judder when the feedback link in the navbar was hovered over.
Gallery page:
* Redesign the gallery using smaller tiles and new images. Increase the number of tiles loaded at a time from 10 to 24.
* Remove the video from the front page, and the "Dive into an exploration" heading. Replace both of these with a blurb directing users to the About page.
* Show rating information in the exploration summary tiles if at least one rating is received (rather than waiting for there to be at least three ratings).
Profile page:
* Fully redesign the profile page, adding a first-contributed date, a field for subject interests, an impact score, and a list of created/edited explorations.
* Add links to the profile page from both the Preferences page and the top-right menu.
* Add new backend jobs to compute a user impact score, the list of contributors to each exploration, the list of explorations created or edited by a user, the first contribution date of a user, and the first date on which an exploration was published.
Interactions:
* Create a new interaction for inputting and evaluating math expressions.
* Build a framework for evaluating learner answers in the frontend, and migrate the following interactions: ImageClickInput, ItemSelectionInput, LogicProof, MusicNotesInput, NumericInput and SetInput.
* EndExploration: Change the displayed name from 'End Conversation' to 'End Exploration'.
* EndExploration: Use the new summary tiles to display exploration recommendations.
* ItemSelectionInput: Fix a bug in the implementation of the "DoesNotContainAtLeastOneOf" rule.
* LogicProof: Extend the timeout for the frontend tests which checks the interaction's evaluation speed, since these tests occasionally fail on slow machines.
Editor page:
* Allow moderators to send emails when unpublishing or featuring explorations.
* Prevent an exploration from being saved if there are critical interaction validation errors.
* Restyle the history page to use checkboxes instead of radio buttons.
* Fix a bug that prevented the title of a state from showing up when the corresponding node in the exploration graph was hovered over.
Other pages:
* Remove some unnecessary warnings that were triggered when a user moved to another page while there was a pending HTTP request.
* Fix an issue where the site feedback link at the bottom left was blocking content on small screens.
* Update the text on the privacy page for clarity.
* Make the 'development mode' indicator a bit less obtrusive.
Infrastructure
* Rewrite the installation scripts using gulp and a manifest, and add tasks for bundling JS and CSS dependencies in order to reduce the number of backend requests on page load.
* Check that versions of installed node modules are correct when running the setup scripts; if not, download the correct version of the module.
* Fix #1170: Check if pip is present on the developer's machine, and output an error message if it isn't.
* Automatically install a local copy of the numpy dependency.
* Skip the App Engine SDK update check at startup.
* Speed up Travis-CI runs by making the coverage report for backend tests optional.
v2.0.3 (21 Nov 2015)
--------------------
Learner page:
* Add help cards for Oppia's responses for supplemental interactions.
* Increase width of cards without supplements.
* Animate changes in card widths.
* Change the 'Previous responses' heading to 'Previous answers'.
Interactions:
* Fix a bug where rule fields of type CodeString default to None instead of the empty string.
Editor page:
* Partially fix a bug where the save and publish buttons drop off the navbar on small screens.
Rich-text editor components:
* Fix a bug where images overspill their boundaries in Firefox.
* Fix a bug that caused images to display inline; they should display as centered block elements instead.
* Remove whitespace around links.
Other pages:
* Make the site feedback form more prominent.
* Add a frontend learner view for collections.
Infrastructure:
* Reduce the time taken for backend tests by splitting up the jobs files.
* Rename test scripts to run_backend_tests.sh, run_frontend_tests.sh and run_e2e_tests.sh.
* Create a run_tests.sh script to run all of the tests.
* Run all tests on deployment, instead of just the backend ones.
v2.0.2 (8 Nov 2015)
-------------------
Learner page:
* Add conversation bubbles to the conversation skin.
* Remove the card-level feedback icon.
* On mobile devices, do not autofocus form fields.
