 The above represents the core, stable dependency which brings in the entirety of Cats Effect. This is *most likely* what you want. All current Cats Effect releases are published for Scala 2.12, 2.13, 3.0, and Scala.js 1.7.

 If you're a middleware framework (like [Fs2](https://fs2.io/)), you probably want to depend on **std**, which gives you access to `Queue`, `Semaphore`, and much more without introducing a hard-dependency on `IO` outside of your tests:
 
 ```scala
 libraryDependencies ++= Seq(
-  "org.typelevel" %% "cats-effect-std" % "3.4.10",
-  "org.typelevel" %% "cats-effect"     % "3.4.10" % Test)
+  "org.typelevel" %% "cats-effect-std" % "3.4.11",
+  "org.typelevel" %% "cats-effect"     % "3.4.11" % Test)
 ```
 
 You may also find some utility in the **testkit** and **kernel-testkit** projects, which contain `TestContext`, generators for `IO`, and a few other things:
 
 ```scala
-libraryDependencies += "org.typelevel" %% "cats-effect-testkit" % "3.4.10" % Test
+libraryDependencies += "org.typelevel" %% "cats-effect-testkit" % "3.4.11" % Test
 ```
 
 Cats Effect provides backward binary compatibility within the 2.x and 3.x version lines, and both forward and backward compatibility within any major/minor line. This is analogous to the versioning scheme used by Cats itself, as well as other major projects such as Scala.js. Thus, any project depending upon Cats Effect 2.2.1 can be used with libraries compiled against Cats Effect 2.0.0 or 2.2.3, but *not* with libraries compiled against 2.3.0 or higher.
