+I've made some changes in the past few days to the CI setup for the
+[yesodweb/yesod repo](https://github.com/yesodweb/yesod) that I
+thought contributors may be interested in knowing about.
+
+* We were regularly running into build timeouts on OS X on Travis. To
+  work around this, we no longer build benchmarks and Haddocks on OS
+  X, and compile with
+  `-O0`. [Relevant Travis changes](https://github.com/yesodweb/yesod/commit/07147f42c2cbb47fddc4c67587e629a74c22fdd6)
+* I've (finally) bit the bullet and made the repo compile with `-Wall
+  -Werror` enabled, at least for recent versions of GHC. From now on,
+  PRs will need to maintain
+  warning-cleanliness. [Relevant Travis changes](https://github.com/yesodweb/yesod/commit/52f67fb04bebd050aa27b4a13fe2ca73aedf25f2#diff-354f30a63fb0907d4ad57269548329e3R178)
+* There's now an AppVeyor configuration, so PRs can be checked against
+  Windows (in addition to the existing Linux and OS X coverage
+  provided by Travis). This did, in fact, reveal
+  [two](https://github.com/yesodweb/yesod/commit/954f813569278ea80df61942537c91c1ab79d78e)
+  [issues](https://github.com/yesodweb/yesod/commit/1bc1ef5a35e0fae15ee990fa1876cdc91a2fc4e3)
+  around line
+  endings. [Relevant AppVeyor addition](https://github.com/yesodweb/yesod/commit/e90b31bb4a57d468c5d8428f7d84fe0ec31bea41).
+
+Nothing major, just a few changes that contributors should be aware
+of. Hopefully that green checkmark on a PR will now have a few less of
+both false positives and false negatives.
