The README states:
Get an Eclipse IDE for JavaScript and Web developers: download from https://download.eclipse.org/wildwebdeveloper/releases/latest/IDEs , unpack and run.
However the latest version that has the "IDEs" section is Eclipse Wild Web Developer 1.3.3
Did Eclipse maintainers forget to publish the standalone Wild Web Developer IDE packages after version 1.3.3, or did development change and remove the standalone IDEs with the intention of only having the plugin available post 1.3.3, making the README no longer accurate?
