-# SemVer
-
-The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
-
-* Parse semantic versions
-* Sort semantic versions
-* Check if a semantic version fits within a set of constraints
-* Optionally work with a `v` prefix
-
-[![Stability:
-Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
-[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
-
-If you are looking for a command line tool for version comparisons please see
-[vert](https://github.com/Masterminds/vert) which uses this library.
-
-## Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-```go
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-```
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
-
-## Sorting Semantic Versions
-
-A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
-package from the standard library. For example,
-
-```go
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-```
-
-## Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-```go
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-```
-
-## Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-* `=`: equal (aliased to no operator)
-* `!=`: not equal
-* `>`: greater than
-* `<`: less than
-* `>=`: greater than or equal to
-* `<=`: less than or equal to
-
-## Working With Pre-release Versions
-
-Pre-releases, for those not familiar with them, are used for software releases
-prior to stable or generally available releases. Examples of pre-releases include
-development, alpha, beta, and release candidate releases. A pre-release may be
-a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
-order of precidence, pre-releases come before their associated releases. In this
-example `1.2.3-beta.1 < 1.2.3`.
-
-According to the Semantic Version specification pre-releases may not be
-API compliant with their release counterpart. It says,
-
-> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
-
-SemVer comparisons without a pre-release comparator will skip pre-release versions.
-For example, `>=1.2.3` will skip pre-releases when looking at a list of releases
-while `>=1.2.3-0` will evaluate and find pre-releases.
-
-The reason for the `0` as a pre-release version in the example comparison is
-because pre-releases can only contain ASCII alphanumerics and hyphens (along with
-`.` separators), per the spec. Sorting happens in ASCII sort order, again per the spec. The lowest character is a `0` in ASCII sort order (see an [ASCII Table](http://www.asciitable.com/))
-
-Understanding ASCII sort ordering is important because A-Z comes before a-z. That
-means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
-sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
-the spec specifies.
-
-## Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-## Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `>= 1.2.x` is equivalent to `>= 1.2.0`
-* `<= 2.x` is equivalent to `< 3`
-* `*` is equivalent to `>= 0.0.0`
-
-## Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-* `~1` is equivalent to `>= 1, < 2`
-* `~2.3` is equivalent to `>= 2.3, < 2.4`
-* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `~1.x` is equivalent to `>= 1, < 2`
-
-## Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-* `^0.0.1` is equivalent to `>= 0.0.1, < 1.0.0`
-* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-* `^2.3` is equivalent to `>= 2.3, < 3`
-* `^2.x` is equivalent to `>= 2.0.0, < 3`
-
-# Validation
-
-In addition to testing a version against a constraint, a version can be validated
-against a constraint. When validation fails a slice of errors containing why a
-version didn't meet the constraint is returned. For example,
-
-```go
-    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-
-    // Validate a version against a constraint.
-    a, msgs := c.Validate(v)
-    // a is false
-    for _, m := range msgs {
-        fmt.Println(m)
-
-        // Loops over the errors which would read
-        // "1.3 is greater than 1.2.3"
-        // "1.3 is less than 1.4"
-    }
-```

-/*
-Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
-
-Specifically it provides the ability to:
-
-    * Parse semantic versions
-    * Sort semantic versions
-    * Check if a semantic version fits within a set of constraints
-    * Optionally work with a `v` prefix
-
-Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the documentation at https://godoc.org/github.com/Masterminds/semver.
-
-Sorting Semantic Versions
-
-A set of versions can be sorted using the `sort` package from the standard library.
-For example,
-
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-
-Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, err := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-
-Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-    * `=`: equal (aliased to no operator)
-    * `!=`: not equal
-    * `>`: greater than
-    * `<`: less than
-    * `>=`: greater than or equal to
-    * `<=`: less than or equal to
-
-Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-    * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-    * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-    * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `>= 1.2.x` is equivalent to `>= 1.2.0`
-    * `<= 2.x` is equivalent to `<= 3`
-    * `*` is equivalent to `>= 0.0.0`
-
-Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-    * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-    * `~1` is equivalent to `>= 1, < 2`
-    * `~2.3` is equivalent to `>= 2.3, < 2.4`
-    * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `~1.x` is equivalent to `>= 1, < 2`
-
-Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-    * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-    * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-    * `^2.3` is equivalent to `>= 2.3, < 3`
-    * `^2.x` is equivalent to `>= 2.0.0, < 3`

+
+## 3.0.1 (2019-09-13)
+
+### Fixed
+
+- #125: Fixes issue with module path for v3
+
+## 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.
+
+## 1.5.0 (2019-09-11)
+
+### Added
+
+- #103: Add basic fuzzing for `NewVersion()` (thanks @jesse-c)

+
+### 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.

+
+- Issue #9: Speed up version comparison performance (thanks @sdboyer)

+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix
+
+[![Stability:
+Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
+[![](https://github.com/Masterminds/semver/workflows/Tests/badge.svg)](https://github.com/Masterminds/semver/actions)
+[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/semver/v3)
+[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
+
+If you are looking for a command line tool for version comparisons please see
+[vert](https://github.com/Masterminds/vert) which uses this library.
+
+## Package Versions
+
+There are three major versions fo the `semver` package.
+
+* 3.x.x is the new stable and active version. This version is focused on constraint
+  compatibility for range handling in other tools from other languages. It has
+  a similar API to the v1 releases. The development of this version is on the master
+  branch. The documentation for this version is below.
+* 2.x was developed primarily for [dep](https://github.com/golang/dep). There are
+  no tagged releases and the development was performed by [@sdboyer](https://github.com/sdboyer).
+  There are API breaking changes from v1. This version lives on the [2.x branch](https://github.com/Masterminds/semver/tree/2.x).
+* 1.x.x is the most widely used version with numerous tagged releases. This is the
+  previous stable and is still maintained for bug fixes. The development, to fix
+  bugs, occurs on the release-1 branch. You can read the documentation [here](https://github.com/Masterminds/semver/blob/release-1/README.md).
+
+## Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an error is returned if there is an issue parsing the
+version. For example,
+
+    v, err := semver.NewVersion("1.2.3-beta.1+build345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. Getting the original string is useful if the semantic version was coerced
+into a valid form.
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+```go
+raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+vs := make([]*semver.Version, len(raw))
+for i, r := range raw {
+    v, err := semver.NewVersion(r)

+
+## Checking Version Constraints
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other uses `Constraints`. There are some important
+differences to notes between these two methods of comparison.
+
+1. When two versions are compared using functions such as `Compare`, `LessThan`,
+   and others it will follow the specification and always include prereleases
+   within the comparison. It will provide an answer that is valid with the
+   comparison section of the spec at https://semver.org/#spec-item-11
+2. When constraint checking is used for checks or validation it will follow a
+   different set of rules that are common for ranges with tools like npm/js
+   and Rust/Cargo. This includes considering prereleases to be invalid if the
+   ranges does not include one. If you want to have it include pre-releases a
+   simple solution is to include `-0` in your range.
+3. Constraint ranges can have some complex rules including the shorthand use of
+   ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns while PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+c, err := semver.NewConstraint(">= 1.2.3")
+if err != nil {
+    // Handle constraint not being parsable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+    // Handle version not being parsable.
+}
+// Check if the version meets the constraints. The a variable will be true.
+a := c.Check(v)
+```
+
+### Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of space or comma separated AND comparisons. These are then separated by || (OR)
+comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+* `=`: equal (aliased to no operator)
+* `!=`: not equal
+* `>`: greater than
+* `<`: less than
+* `>=`: greater than or equal to
+* `<=`: less than or equal to
+
+### Working With Prerelease Versions
+
+Pre-releases, for those not familiar with them, are used for software releases
+prior to stable or generally available releases. Examples of prereleases include
+development, alpha, beta, and release candidate releases. A prerelease may be
+a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
+order of precedence, prereleases come before their associated releases. In this
+example `1.2.3-beta.1 < 1.2.3`.
+
+According to the Semantic Version specification prereleases may not be
+API compliant with their release counterpart. It says,
+
+> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
+
+SemVer comparisons using constraints without a prerelease comparator will skip
+prerelease versions. For example, `>=1.2.3` will skip prereleases when looking
+at a list of releases while `>=1.2.3-0` will evaluate and find prereleases.
+
+The reason for the `0` as a pre-release version in the example comparison is
+because pre-releases can only contain ASCII alphanumerics and hyphens (along with
+`.` separators), per the spec. Sorting happens in ASCII sort order, again per the
+spec. The lowest character is a `0` in ASCII sort order
+(see an [ASCII Table](http://www.asciitable.com/))
+
+Understanding ASCII sort ordering is important because A-Z comes before a-z. That
+means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
+sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
+the spec specifies.
+
+### Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+* `1.2 - 1.4.5` which is equivalent to `>= 1.2 <= 1.4.5`
+* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
+
+### Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the patch level comparison (see tilde below). For example,
+
+* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `>= 1.2.x` is equivalent to `>= 1.2.0`
+* `<= 2.x` is equivalent to `< 3`
+* `*` is equivalent to `>= 0.0.0`
+
+### Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+* `~1` is equivalent to `>= 1, < 2`
+* `~2.3` is equivalent to `>= 2.3, < 2.4`
+* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `~1.x` is equivalent to `>= 1, < 2`
+
+### Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. This is useful when comparisons of API versions as a
+major change is API breaking. For example,
+
+* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+* `^2.3` is equivalent to `>= 2.3, < 3`
+* `^2.x` is equivalent to `>= 2.0.0, < 3`
+* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+* `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+* `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+* `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+## Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+if err != nil {
+    // Handle constraint not being parseable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+    // Handle version not being parseable.
+}
+
+// Validate a version against a constraint.
+a, msgs := c.Validate(v)
+// a is false
+for _, m := range msgs {
+    fmt.Println(m)
+
+    // Loops over the errors which would read
+    // "1.3 is greater than 1.2.3"
+    // "1.3 is less than 1.4"
+}
+```

+Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
+
+Specifically it provides the ability to:
+
+    * Parse semantic versions
+    * Sort semantic versions
+    * Check if a semantic version fits within a set of constraints
+    * Optionally work with a `v` prefix
+
+Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. 1.2) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an optional error can be returned if there is an issue
+parsing the version. For example,
+
+    v, err := semver.NewVersion("1.2.3-beta.1+b345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. For more details please see the documentation
+at https://godoc.org/github.com/Masterminds/semver.
+
+Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+    vs := make([]*semver.Version, len(raw))
+	for i, r := range raw {
+		v, err := semver.NewVersion(r)
+		if err != nil {
+			t.Errorf("Error parsing version: %s", err)
+		}
+
+		vs[i] = v
+	}
+
+	sort.Sort(semver.Collection(vs))
+
+Checking Version Constraints and Comparing Versions
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other is using Constraints. There are some important
+differences to notes between these two methods of comparison.
+
+1. When two versions are compared using functions such as `Compare`, `LessThan`,
+   and others it will follow the specification and always include prereleases
+   within the comparison. It will provide an answer valid with the comparison
+   spec section at https://semver.org/#spec-item-11
+2. When constraint checking is used for checks or validation it will follow a
+   different set of rules that are common for ranges with tools like npm/js
+   and Rust/Cargo. This includes considering prereleases to be invalid if the
+   ranges does not include on. If you want to have it include pre-releases a
+   simple solution is to include `-0` in your range.
+3. Constraint ranges can have some complex rules including the shorthard use of
+   ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns which PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+    c, err := semver.NewConstraint(">= 1.2.3")
+    if err != nil {
+        // Handle constraint not being parsable.
+    }
+
+    v, err := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parsable.
+    }
+    // Check if the version meets the constraints. The a variable will be true.
+    a := c.Check(v)
+
+Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma or space separated AND comparisons. These are then separated by || (OR)
+comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3. This can also be written as
+`">= 1.2, < 3.0.0 || >= 4.2.3"`
+
+The basic comparisons are:
+
+    * `=`: equal (aliased to no operator)
+    * `!=`: not equal
+    * `>`: greater than
+    * `<`: less than
+    * `>=`: greater than or equal to
+    * `<=`: less than or equal to
+
+Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+    * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+    * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
+
+Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the tilde operation. For example,
+
+    * `1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
+    * `>= 1.2.x` is equivalent to `>= 1.2.0`
+    * `<= 2.x` is equivalent to `<= 3`
+    * `*` is equivalent to `>= 0.0.0`
+
+Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+    * `~1.2.3` is equivalent to `>= 1.2.3 < 1.3.0`
+    * `~1` is equivalent to `>= 1, < 2`
+    * `~2.3` is equivalent to `>= 2.3 < 2.4`
+    * `~1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
+    * `~1.x` is equivalent to `>= 1 < 2`
+
+Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. This is useful when comparisons of API versions as a
+major change is API breaking. For example,
+
+    * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+    * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+    * `^2.3` is equivalent to `>= 2.3, < 3`
+    * `^2.x` is equivalent to `>= 2.0.0, < 3`
+    * `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+    * `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+    * `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+    * `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+    * `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+    if err != nil {
+        // Handle constraint not being parseable.
+    }
+
+    v, _ := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parseable.
+    }
+
+    // Validate a version against a constraint.
+    a, msgs := c.Validate(v)
+    // a is false
+    for _, m := range msgs {
+        fmt.Println(m)
+
+        // Loops over the errors which would read
+        // "1.3 is greater than 1.2.3"
+        // "1.3 is less than 1.4"
+    }

+## IMPORTANT NOTES
+
+Sprig leverages [mergo](https://github.com/imdario/mergo) to handle merges. In
+its v0.3.9 release there was a behavior change that impacts merging template
+functions in sprig. It is currently recommended to use v0.3.8 of that package.
+Using v0.3.9 will cause sprig tests to fail. The issue in mergo is tracked at
+https://github.com/imdario/mergo/issues/139.
+
+## Package Versions
+
+There are two active major versions of the `sprig` package.
+
+* v3 is currently stable release series on the `master` branch. The Go API should
+  remain compatible with v2, the current stable version. Behavior change behind
+  some functions is the reason for the new major version.
+* v2 is the previous stable release series. It has been more than three years since
+  the initial release of v2. You can read the documentation and see the code
+  on the [release-2](https://github.com/Masterminds/sprig/tree/release-2) branch.
+  Bug fixes to this major version will continue for some time.
+
