v4.10.0 - 2022-12-27

Security

  • We are deprecating JWT middleware in this repository. Please use https://github.com/labstack/echo-jwt instead.

    JWT middleware is moved to separate repository to allow us to bump/upgrade version of JWT implementation (github.com/golang-jwt/jwt) we are using which we can not do in Echo core because this would break backwards compatibility guarantees we try to maintain.

  • This minor version bumps minimum Go version to 1.17 (from 1.16) due golang.org/x/ packages we depend on. There are several vulnerabilities fixed in these libraries.

    Echo still tries to support last 4 Go versions but there are occasions we can not guarantee this promise.

  • Additional configuration options for RequestLogger and Logger middleware #2341
  • Add route to request log #2162

v4.5.0 - 2021-08-01

Important notes

A BREAKING CHANGE is introduced for JWT middleware users. The JWT library used for the JWT middleware had to be changed from github.com/dgrijalva/jwt-go to github.com/golang-jwt/jwt due former library being unmaintained and affected by security issues. The github.com/golang-jwt/jwt project is a drop-in replacement, but supports only the latest 2 Go versions. So for JWT middleware users Go 1.15+ is required. For detailed information please read #1940

To change the library imports in all .go files in your project replace all occurrences of dgrijalva/jwt-go with golang-jwt/jwt.

For Linux CLI you can use:

find -type f -name "*.go" -exec sed -i "s/dgrijalva\/jwt-go/golang-jwt\/jwt/g" {} \;
go mod tidy

Fixes

  • Change JWT library to github.com/golang-jwt/jwt #1946

v4.4.0 - 2021-07-12

Fixes

  • Split HeaderXForwardedFor header only by comma #1878

  • Adding tests for Echo#Host #1895
  • Adds RequestIDHandler function to RequestID middleware #1898
  • Allow for custom JSON encoding implementations #1880

v4.3.0 - 2021-05-08

Important notes

  • Route matching has improvements for following cases:
    1. Correctly match routes with parameter part as last part of route (with trailing backslash)
    2. Considering handlers when resolving routes and search for matching http method handler
  • Echo minimal Go version is now 1.13.

Fixes

  • When url ends with slash first param route is the match #1804

v4.2.0 - 2021-02-11

Important notes

The behaviour for binding data has been reworked for compatibility with echo before v4.1.11 by enforcing explicit tagging for processing parameters. This may break your code if you expect combined handling of query/path/form params. Please see the updated documentation for request and binding

The handling for rewrite rules has been slightly adjusted to expand * to a non-greedy (.*?) capture group. This is only relevant if multiple asterisks are used in your rules. Please see rewrite and proxy for details.
