Does Combine 4 require nightly?

[fulmicoton]

As I am trying to update the requirement to combine@4 in tantivy i hit the following error :

use of unstable library feature 'float_to_from_bytes'
   --> /home/paul/.cargo/registry/src/github.com-1ecc6299db9ec823/combine-4.0.0/src/parser/byte.rs:468:34

Is nightly required now?

No, but it does require 1.40 as float_to_from_bytes was stabilized in that (letting me drop the byteorder dependency). If that is a problem it would be possible to use features to conditionally use bytorder to lower the needed rust version or to conditionally disable this parser.

Thanks for the quick reply.

As you wish. I can also just wait a month or two before updating.
