Module libloading::changelog::r0_4_0

Release 0.4.0 (2017-05-01)

• Remove build-time dependency on target_build_utils (and by extension serde/phf);
• Require at least version 1.14.0 of rustc to build;
  • Actually, it is cargo which has to be more recent here. The one shipped with rustc 1.14.0 is what’s being required from now on.
