+This is technically a hotfix patch release for 1.18.0, which was discovered to be [severely broken](https://github.com/scala-js/scala-js/issues/5107), and was therefore never announced.
+These release notes therefore present it as a "minor release" compared to 1.17.0.
 
 This release drops support for Scala 2.12.{2-5} and 2.13.{0-2}.

 If upgrading from Scala.js 0.6.x, make sure to read [the release notes of Scala.js 1.0.0]({{ BASE_PATH }}/news/2020/02/25/announcing-scalajs-1.0.0/) first, as they contain a host of important information, including breaking changes.

+This is a **minor** release, compared to 1.17.0:
 
 * It is backward binary compatible with all earlier versions in the 1.x series: libraries compiled with 1.0.x through 1.17.x can be used with 1.18.0 without change.
 * It is *not* forward binary compatible with 1.17.x: libraries compiled with 1.18.0 cannot be used with 1.17.x or earlier.
 * It is *not* entirely backward source compatible: it is not guaranteed that a codebase will compile *as is* when upgrading from 1.17.x (in particular in the presence of `-Xfatal-warnings`).
 
+Technically 1.18.1 is a patch release with respect to 1.18.0.
+Our usual patch version guarantees do apply, despite the retraction of 1.18.0.

 As a reminder, libraries compiled with 0.6.x cannot be used with Scala.js 1.x; they must be republished with 1.x first.
 
 ## Changes with compatibility concerns
 
 ### Enforce stricter rules on the use of `this` in the IR of constructors
 
 Exceptionally, **this is theoretically a binary-breaking change**.
-It is possible for previously valid IR (Intermediate Representation, as published in binaries on Maven Central) to be rejected by Scala.js 1.18.0.
+It is possible for previously valid IR (Intermediate Representation, as published in binaries on Maven Central) to be rejected by Scala.js 1.18.x.
 
 We now enforce, during IR checking (by default, only enabled in `fullLink` builds), that constructors abide by stricter rules.
 Before calling their `super` constructor (or delegate `this()` constructor), they may not refer to the `this` instance.
