# Change Log
All notable changes to this project will be documented in this file.
## [3.0.0]
### Changed
- **BREAKING**: `jwt.verify` now requires an `algorithm` parameter, and
`jws.createVerify` requires an `algorithm` option. The `"alg"` field
signature headers is ignored. This mitigates a critical security flaw
in the library which would allow an attacker to generate signatures with
arbitrary contents that would be accepted by `jwt.verify`. See
https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/
for details.
## [2.0.0] - 2015-01-30
### Changed
- **BREAKING**: Default payload encoding changed from `binary` to
`utf8`. `utf8` is a is a more sensible default than `binary` because
many payloads, as far as I can tell, will contain user-facing
strings that could be in any language. (<code>[6b6de48]</code>)
- Code reorganization, thanks [@fearphage]! (<code>[7880050]</code>)
### Added
- Option in all relevant methods for `encoding`. For those few users
that might be depending on a `binary` encoding of the messages, this
is for them. (<code>[6b6de48]</code>)
