 Next generation concurrency primitives for Clojure built on top of Project Loom

 ### Project State
 
-Tapestry is in beta. As the APIs in loom have stabilized so too has tapestry.
-Still, breaking changes may happen as we evolve the library. Pre-`1.0.0` we will
-use the minor version to denote breaking changes.
+Tapestry is still pre-1.0. As the APIs in loom have stabilized so too has tapestry.
 
 Tapestry is being used in production for several of Teknql's projects and has
 more or less replaced both `clojure.core/future` and `manifold.deferred/future`.
 
+It is the ambition of the project to eventually drop manifold entirely, at which
+point it will likely hit 1.0.
+
 ## Installation
 
 Add to your deps.edn:
 
 ```
-teknql/tapestry {:mvn/version "0.3.0-SNAPSHOT"}
-```
-
-
-### Installing JDK 19
-
-You will need to be running a recent JDK 19 release
-
-You can download the latest version from the [JDK 19 Site](https://jdk.java.net/19/).
-
-On linux, installing it looks something like this:
-
-```
-tar -xvzf openjdk-19_linux-x64_bin.tar.gz
-sudo mv jdk-19/ /usr/lib/jvm/jdk-19
-cd /usr/lib/jvm
-sudo rm default default-runtime
-sudo ln -s jdk-19 $PWD/default
-sudo ln -s jdk-19 $PWD/default-runtime
-```
-
-Then you will need to add the `--enable-preview` flag to your JVM opts. In deps.edn it looks like:
-
-```
-{:aliases
- {:preview
-  {:jvm-opts ["--enable-preview"]}}}
+teknql/tapestry {:mvn/version "0.4.0"}
 ```
 
-```
-clojure -A:preview
-```
-
-Alternatively, you can install a loom preview build via [sdkman](https://sdkman.io/install):
-
-```
-$ sdk install java 17.ea.2.lm-open
-    ...
-Installing: java 17.ea.2.lm-open
-Done installing!
-
-Do you want java 17.ea.2.lm-open to be set as default? (Y/n): n
-$ sdk use java 17.ea.2.lm-open
-
-Using java version 17.ea.2.lm-open in this shell.
-```
-The sdkman maintainers update the loom preview build often. To find the current version identifier for the loom preview build run `sdk list java` and look for the identifier containing "lm-open".

 ## Showcase
 
-Full API documentation can be seen in the `tapestry.core` ns itself. Right now we can't build
-the documentation using clj-doc. You can track the issue [here](https://github.com/cljdoc/cljdoc/issues/275)
