 associated libraries, especially with regards to changes visible to
 the user of the Subplot software.
 
+# Version 0.3.1, released 2021-11-16
+
+* The primary purpose of this release is to make the `PATH` bug fix
+  available via crates.io, to fix use of Subplot in the Sequoia-PGP
+  project. There are no breaking changes, so only the patch level of
+  the version number is incremented.
+
+* The licence of Subplot has been changed to
+  [MIT-0](https://mit-license.org/), to make it as simple as possible
+  to use Subplot on other projects, without having to worry about
+  license compatibility. Previously, this was technically possible,
+  but the Subplot licence situation was complex enough that it caused
+  people ask questions.
+
+  The Subplot developers prefer, for Subplot, to maximize adoption and
+  though they would favor a copyleft licence otherwise, they're
+  willing to compromise this time.
+
+* A bug has been fixed in the Rust `lib/runcmd` function
+  implementation to prepend a directory to the `PATH`, in the
+  `subplotlib::steplibrary::runcmd::try_to_run_in` function. The bug
+  meant that the directories in `PATH` ended up in the wrong order.
