Hopefully the next release this spring, but there are no definite plans in the works at the moment. Anything in the previous editor versions for water allocation was not correct anyhow. If you need to use water allocation soon, please work outside the editor for that part.
However, you also mention a problem with pesticides? Is that an unrelated issue? Let me know any errors or details about that. Pesticides should be working through the editor.
Thanks!
