## 3.0.0 (2019-09-12)

This is a major release of the semver package which includes API changes. The Go
API is compatible with ^1. The Go API was not changed because many people are using
`go get` without Go modules for their applications and API breaking changes cause
errors which we have or would need to support.

The changes in this release are the handling based on the data passed into the
functions. These are described in the added and changed sections below.

### Added

- StrictNewVersion function. This is similar to NewVersion but will return an
  error if the version passed in is not a strict semantic version. For example,
  1.2.3 would pass but v1.2.3 or 1.2 would fail because they are not strictly
  speaking semantic versions. This function is faster, performs fewer operations,
  and uses fewer allocations than NewVersion.
- Fuzzing has been performed on NewVersion, StrictNewVersion, and NewConstraint.
  The Makefile contains the operations used. For more information on you can start
  on Wikipedia at https://en.wikipedia.org/wiki/Fuzzing
- Now using Go modules

### Changed

- NewVersion has proper prerelease and metadata validation with error messages
  to signal an issue with either of them
- ^ now operates using a similar set of rules to npm/js and Rust/Cargo. If the
  version is >=1 the ^ ranges works the same as v1. For major versions of 0 the
  rules have changed. The minor version is treated as the stable version unless
  a patch is specified and then it is equivalent to =. One difference from npm/js
  is that prereleases there are only to a specific version (e.g. 1.2.3).
  Prereleases here look over multiple versions and follow semantic version
  ordering rules. This pattern now follows along with the expected and requested
  handling of this packaged by numerous users.

### Fixed

- #24: Fixed edge case issue where constraint "> 0" does not handle "0.0.1-alpha"
  properly.

## Release 1.2.0 (2016-11-04)

### Added

- #20: Added MustParse function for versions (thanks @adamreese)
- #15: Added increment methods on versions (thanks @mh-cbon)

### Fixed

- Issue #21: Per the SemVer spec (section 9) a pre-release is unstable and
  might not satisfy the intended compatibility. The change here ignores pre-releases
  on constraint checks (e.g., ~ or ^) when a pre-release is not part of the
  constraint. For example, `^1.2.3` will ignore pre-releases while
  `^1.2.3-alpha` will include them.
