+## 2.1.4 (January 5, 2020)
+
+Bugfixes:
+
+  - Fix `net-http-pipeline` no longer being allowed in Gemfiles if already installed in the system due to our vendored version of `net-http-persistent` optionally requiring it [#7529](https://github.com/bundler/bundler/pull/7529)
+  - Fix inline gems no longer being requirable if no Gemfile is present in the directory hierarchy [#7537](https://github.com/bundler/bundler/pull/7537)
+
 ## 2.1.3 (January 2, 2020)
