# Authlete 3.0 Release Notes - May 2026

##### Version Number : 3.0.32

# Overview

This minor update introduces changes for Authlete 3.0.
This new version is available from May 28th (Thu).

# New Features & Improvements

## Platform components update

Upgraded Jarkarta, DataNucleus, HikariCP, Mockito, and other maven dependencies to supported versions for Jetty 12 and Java 25.

## Direct endpoints clean up

Cleaned up deprecated code in service and client direct endpoints.

# Specs support

## OpenID Connect Back-Channel Logout 1.0 support

Implemented support for `OpenID Connect Back-Channel Logout 1.0`. For more information, check the documentation [here](https://openid.net/specs/openid-connect-backchannel-1_0.html).

# Bug fixes

## Grant Management replace flow fix

Fixed an issue where the token endpoint would fail with `A050101` whenever `grant_management_action=replace` was used with the authorization code grant type.

## Invalid URI error fix

Fixed an issue where calling `/auth/authorization` with parameters that include an invalid URI such as `request_uri=invalid\` would result in a 500 error.

## Persistent token cleanup fix

Fixed an issue where some persistent tokens would be targeted by the token clean up job if they haven't been used for a certain period of time.

## Loopback redirection URI fix

Fixed an issue where a service with `loopbackRedirectionUriVariable=true` and `openid` included in the authorization request’s `scope` would cause the `/token` call to fail with `invalid_grant`, even though the client sends the same `redirect_uri` at both `/authorization` and `/token`.
