+## Changes
+
+- Compiler performance has [improved significantly](developer.lightbend.com/blog/2017-06-12-faster-scala-compiler/) and is now [automatically benchmarked](https://scala-ci.typesafe.com/grafana/) after each change.
+- A new [optimizer setting](https://github.com/scala/scala/pull/5964) `-opt-inline-from` limits the classes from which the inliner will copy code. `scalac -opt-inline-from:help` provides [detailed help](https://gist.github.com/retronym/29932ea76712ff374d1363c9eda6eabe).
+- The presentation compiler has [improved support for implicit macros](https://github.com/scala/scala/pull/5929), which should improve the experience with libraries based on Shapeless. It also has [better support](https://github.com/scala/scala/pull/5927) for code completion for dependently typed methods.
+
+Further [significant changes](https://github.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.12.3%20label%3Arelease-notes) since 2.12.2 include:
+
+- [#5978](https://github.com/scala/scala/pull/5978) Avoid calling static initializers when reflecting on Java classes
+- [#5964](https://github.com/scala/scala/pull/5589) New setting `-opt-inline-from` to control where to inline from
+- [#5931](https://github.com/scala/scala/pull/5931) Upgrade to jline 2.14.4
+- [#5880](https://github.com/scala/scala/pull/5880) bundle newer scala-parser-combinators (1.0.5->1.0.6)
+- [#5879](https://github.com/scala/scala/pull/5879) -Xlint:unused -Ywarn-unused is intuitive
+- [#5848](https://github.com/scala/scala/pull/5848) add per-phase profiling to scalac
+
+For more information, check out [all closed bugs](https://github.com/scala/bug/issues?q=is%3Aclosed%20milestone%3A2.12.3) and [merged PRs](https://github.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.12.3).
+
+As usual for minor releases, Scala 2.12.3 is binary compatible with the whole Scala 2.12 series.
