 # Changelog
 
+## Version 1.3.2
+
+*February 3, 2016*
+
+A small bugfix for slightly incorrect background colors on code samples in some cases.
+
+## Version 1.3.1
+
+*January 31, 2016*
+
+A small bugfix for incorrect whitespace in code blocks.
+
+## Version 1.3
+
+*January 27, 2016*
+
+We've upgraded Middleman and a number of other dependencies, which should fix quite a few bugs.
+
+Instead of `rake build` and `rake deploy`, you should now run `bundle exec middleman build --clean` to build your server, and `./deploy.sh` to deploy it to Github Pages.

-# Contributing to Slate
+# Before You Submit an Issue
 
-Thanks for contributing to Slate! A couple of quick guidelines for submitting PRs:
+- Are you using Windows? We unfortunately don't support Windows. You could try using Docker, as outlined in the `README`.
+- Is your version of Slate out of date? We have [upgrade instructions](https://github.com/tripit/slate/wiki/Updating-Slate) in the wiki. You could also try seeing if your problem is reproducible on the latest version of Slate.
 
-- Please point your pull requests at the `dev` branch, and keep your commit messages clear and informative.
+If you answered "no" to each of the questions above, feel free to submit an issue! It's also helpful if you include a code example of your problem (if applicable), we can't help you if you just say "Slate stopped loading for me once I added my documentation" without telling us the problematic documentation.

+# Before You Submit a Pull Request
+
+Thanks for contributing to Slate! A couple of quick guidelines for submitting pull requests:
+
+- **Please point your pull requests at the `dev` branch.** We don't accept pull requests to `master`.
 - Please make sure your contributions work in the most recent version of Chrome, Firefox, and IE.
 - If you're implementing a new feature, even if it's relatively small, it's nice to open an issue before you start so that others know what you're working on and can help make sure you're on the right track.
