-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-- Demonstrating empathy and kindness toward other people
-- Being respectful of differing opinions, viewpoints, and experiences
-- Giving and gracefully accepting constructive feedback
-- Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-- Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-- The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-- Trolling, insulting or derogatory comments, and personal or political attacks
-- Public or private harassment
-- Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-- Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-contact@divlo.fr.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within
-the community.

 # Changelog
 
+## [2.1.0](https://github.com/Thream/socketio-jwt/compare/v2.0.0...v2.1.0) (2021-03-08)
+
+### Features
+
+- add optional `onAuthentication` option to add `user` property in `socket` object ([#62](https://github.com/Thream/socketio-jwt/issues/62)) ([c7f64a6](https://github.com/Thream/socketio-jwt/commit/c7f64a6312a3e1f6f04918cb7cd415ddef7a11e5))
+
+## [2.0.0](https://github.com/Thream/socketio-jwt/compare/v1.1.1...v2.0.0) (2021-02-22)
+
+### Features
+
+- usage of auth option to send credentials ([a14d4e9](https://github.com/Thream/socketio-jwt/commit/a14d4e937b764fdf4fb6b173c55b6f49688766dd))
+
+  See: <https://socket.io/docs/v3/middlewares/#Sending-credentials>
+
+### BREAKING CHANGES
+
+- `extraHeaders` with `Authorization` doesn't work anymore
+
+### Migration
+
+You need to change the way to connect client side.
+
+Before :
+
+```ts
+import { io } from 'socket.io-client'
+
+const socket = io('http://localhost:9000', {
+  extraHeaders: { Authorization: `Bearer ${yourJWT}` }
+})
+```
+
+After :
+
+```ts
+import { io } from 'socket.io-client'
+
+const socket = io('http://localhost:9000', {
+  auth: { token: `Bearer ${yourJWT}` }
+})
+```
+
+## [1.1.1](https://github.com/Thream/socketio-jwt/compare/v1.1.0...v1.1.1) (2021-01-28)
+
+### Bug Fixes
+
+- **types:** decodedToken in secret callback ([c1a9213](https://github.com/Thream/socketio-jwt/commit/c1a9213a527e4c6188328221372e1f40191a790e)), closes [#21](https://github.com/Thream/socketio-jwt/issues/21)
+
+### Documentation
+
+- update server side usage with `jwks-rsa` : get the secret with `key.getPublicKey()` instead of `key.rsaPublicKey`
+
+## [1.1.0](https://github.com/Thream/socketio-jwt/compare/v1.0.1...v1.1.0) (2021-01-07)
+
+### Features
+
+- add algorithms option ([abbabc5](https://github.com/Thream/socketio-jwt/commit/abbabc588e3ea8b906fa0a0dcc83c91a3b5b5ea8))
+- add support for jwks-rsa ([#1](https://github.com/Thream/socketio-jwt/issues/1)) ([261e8d6](https://github.com/Thream/socketio-jwt/commit/261e8d66e2ec6fefb77429abcef8f846d996ecac))
+- improve types by extending socket.io module ([#6](https://github.com/Thream/socketio-jwt/issues/6)) ([84b523f](https://github.com/Thream/socketio-jwt/commit/84b523f4348c81933887f0dc700f438c84bd779a))
+
 ## [1.0.1](https://github.com/Thream/socketio-jwt/compare/v1.0.0...v1.0.1) (2020-12-29)
 
-- docs(readme): fix usage section by correctly importing `authorize`
