-## Setting route prefix
-
-In `v0.2.x` the route prefix could be set by assigning a string of `"pathname"`, `"hash"`, or `"search"` to `m.route.mode`. In `v1.x` this has been replaced by `m.route.prefix` which is a setter function. Passing it an empty string is analogous to using pathname mode. Other options include passing `"#"` for hash and `"?"` for search.

 ## m.request
 
 [m.request](request.md) now returns an [m.prop stream](prop.md) instead of a promise. The main difference is you'll have to use `.run` to get similar functionality as a promise's `.then`:
