travis.yml: we can now run "cabal check" successfully

Hackage won't accept the package with that "hack" in place. If you want to
compile with profiling enabled, please configure the build with
--enable-profiling via "cabal" or "stack" or whatever build driver you're
using.

 # Change Log / Release Notes
 
+## 0.14 (July 30, 2018)
+
+### Bug Fixes
+
+  * The state file that xmonad uses while restarting itself is now
+    removed after it is processed.  This fixes a bug that manifested
+    in several different ways:
+
+    - Names of old workspaces would be resurrected after a restart
+    - Screen sizes would be wrong after changing monitor configuration (#90)
+    - `spawnOnce` stopped working (xmonad/xmonad-contrib#155)
+    - Focus did not follow when moving between workspaces (#87)
+    - etc.
+
+  * Recover old behavior (in 0.12) when `focusFollowsMouse == True`:
+    the focus follows when the mouse enters another workspace
+    but not moving into any window.
+
+  * Compiles with GHC 8.4.1
+
+  * Restored compatability with GHC version prior to 8.0.1 by removing the
+    dependency on directory version 1.2.3.

@@ -59,6 +59,81 @@ Here are some tips for getting your changes merged into xmonad:
     repository.  Include a new configuration file that shows off your
     changes if possible by creating a PR on that repository as well.
 
+  * Make sure you read the section on rebasing and squashing commits
+    below.
+
+## Rebasing and Squashing Commits
+
+Under no circumstances should you ever merge the master branch into
+your feature branch.  This makes it nearly impossible to review your
+changes and we *will not accept your PR* if you do this.
+
+Instead of merging you should rebase your changes on top of the master
+branch.  If a core team member asks you to "rebase your changes" this
+is what they are talking about.
+
+It's also helpful to squash all of your commits so that your pull
+request only contains a single commit.  Again, this makes it easier to
+review your changes and identify the changes later on in the Git
+history.
+
+### How to Rebase Your Changes
+
+The goal of rebasing is to bring recent changes from the master branch
+into your feature branch.  This often helps resolve conflicts where
+you have changed a file that also changed in a recently merged pull
+request (i.e. the `CHANGES.md` file).  Here is how you do that.
+
+  1. Make sure that you have a `git remote` configured for the main
+     repository.  I like to call this remote `upstream`:
+
+        $ git remote add upstream https://github.com/xmonad/xmonad-contrib.git
+
+  2. Pull from upstream and rewrite your changes on top of master.  For
+     this to work you should not have any modified files in your
+     working directory.  Run these commands from within your feature
+     branch (the branch you are asking to be merged):
+
+        $ git fetch --all
+        $ git pull --rebase upstream master
+
+  3. If the rebase was successful you can now push your feature branch
+     back to GitHub.  You need to force the push since your commits
+     have been rewritten and have new IDs:
+
+        $ git push --force-with-lease
+
+  4. Your pull request should now be conflict-free and only contain the
+     changes that you actually made.
+
+### How to Squash Commits
+
+The goal of squashing commits is to produce a clean Git history where
+each pull request contains just one commit.
+
+  1. Use `git log` to see how many commits you are including in your
+     pull request.  (If you've already submitted your pull request you
+     can see this in the GitHub interface.)
+
+  2. Rebase all of those commits into a single commit.  Assuming you
+     want to squash the last four (4) commits into a single commit:
+
+        $ git rebase -i HEAD~4
+
+  3. Git will open your editor and display the commits you are
+     rebasing with the word "pick" in front of them.
+
+  4. Leave the first listed commit as "pick" and change the remaining
+     commits from "pick" to "squash".
+
+  5. Save the file and exit your editor.  Git will create a new commit
+     and open your editor so you can modify the commit message.
+
+  6. If everything was successful you can push your changed history
+     back up to GitHub:
+
+        $ git push --force-with-lease
