anchor.diff:  === MVEL template engine
   
   To use MVEL, you need to add the following _dependency_ to your project:
  -`io.vertx:vertx-web-templ-mvel:3.3.3`. Create an instance of the MVEL template engine using:
  +`io.vertx:vertx-web-templ-mvel:3.4.0-SNAPSHOT`. Create an instance of the MVEL template engine using:
   `io.vertx.ext.web.templ.MVELTemplateEngine#create()`
   
   When using the MVEL template engine, it will by default look for
  
positive.code: means the next one won't be executed until the previous one has completed. If you don't care about orderering and
  don't mind your blocking handlers executing in parallel you can set the blocking handler specifying `ordered` as
  false using `link:../../apidocs/io/vertx/ext/web/Route.html#blockingHandler-io.vertx.core.Handler-boolean-[blockingHandler]`.
