# `jwt-go` Version History

The following version history is kept for historic purposes. To retrieve the current changes of each version, please refer to the change-log of the specific release versions on https://github.com/golang-jwt/jwt/releases.

## 4.0.0

* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`.

## 3.2.2

* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)).
* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)).
* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)).
* Optimized allocations ([#33](https://github.com/golang-jwt/jwt/pull/33)).

## 3.2.1

* **Import Path Change**: See MIGRATION_GUIDE.md for tips on updating your code
	* Changed the import path from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`
* Fixed type confusing issue between `string` and `[]string` in `VerifyAudience` ([#12](https://github.com/golang-jwt/jwt/pull/12)). This fixes CVE-2020-26160 

#### 3.2.0

* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.

#### 3.1.0

* Improvements to `jwt` command line tool
* Added `SkipClaimsValidation` option to `Parser`
* Documentation updates

#### 3.0.0

* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
* Other Additions and Changes
	* Added `Claims` interface type to allow users to decode the claims into a custom type
	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
	* Added several new, more specific, validation errors to error type bitmask
	* Moved examples from README to executable example files
	* Signing method registry is now thread safe
	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)

#### 2.7.0

This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.

* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
* Error text for expired tokens includes how long it's been expired
* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
* Documentation updates

#### 2.6.0

* Exposed inner error within ValidationError
* Fixed validation errors when using UseJSONNumber flag
* Added several unit tests

#### 2.5.0

* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
* Updated/fixed some documentation
* Added more helpful error message when trying to parse tokens that begin with `BEARER `

#### 2.4.0

* Added new type, Parser, to allow for configuration of various parsing parameters
	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
* Fixed some bugs with ECDSA parsing

#### 2.3.0

* Added support for ECDSA signing methods
* Added support for RSA PSS signing methods (requires go v1.4)

#### 2.2.0

* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.

#### 2.1.0

Backwards compatible API change that was missed in 2.0.0.

* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`

#### 2.0.0

There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.

The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.

It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.

* **Compatibility Breaking Changes**
	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
	* `KeyFunc` now returns `interface{}` instead of `[]byte`
	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
    * Added public package global `SigningMethodHS256`
    * Added public package global `SigningMethodHS384`
    * Added public package global `SigningMethodHS512`
* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
    * Added public package global `SigningMethodRS256`
    * Added public package global `SigningMethodRS384`
    * Added public package global `SigningMethodRS512`
* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
* Refactored the RSA implementation to be easier to read
* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`

## 1.0.2

* Fixed bug in parsing public keys from certificates
* Added more tests around the parsing of keys for RS256
* Code refactoring in RS256 implementation.  No functional changes

## 1.0.1

* Fixed panic if RS256 signing method was passed an invalid key

## 1.0.0

* First versioned release
* API stabilized
* Supports creating, signing, parsing, and validating JWT tokens
* Supports RS256 and HS256 signing methods
