+
+About a month after the release of Jekyll v1.3.0, we are releasing
+Jekyll v1.4.0. This release will be the last release to support Ruby
+1.8.7 and our next release will be Jekyll 2.0.0
+
+Here are a few things we think you'll want to know about this release:
+
+* TOML is now a supported markup language for config files.
+
+* Maruku has been updated to 0.7.0 which provides some new features and
+  a ton of bugfixes over the previous 0.6.x releases.
+
+* Plugins are now sorted before they're processed, which can provide a
+  rudimentary way to establish a load order for plugins
+
+For a full run-down, visit our [change log](/docs/history/)!
+
+As always, Jekyll wouldn't be possible without the contributions from
+others in the Jekyll community. We'd like to thank the following people
+for contributing to this release: Anatol Broder, David Sawyer, Greg
+Karékinian, Jordon Bedwell, Matthew Iversen, Persa Zula, and Yi Zeng.
