-We are delighted to announce the ["3rd International Workshop on Reinforcement Learning for Autonomous Accelerators" RL4AA’25](https://rl4aa.github.io/RL4AA25/)! To be held **2 - 4 April 2025** at **DESY** in **Hamburg, Germany**. Following the very successful RL4AA'23 and RL4AA'24 workshops, the goal of this workshop is to exchange experiences and ideas about RL in the context of particle accelerators amongst both experts and beginners.
+We are pleased to announce RL4AA'26, the fourth workshop of the series organised by the **[Reinforcement Learning for Autonomous Accelerators (RL4AA) Collaboration](https://rl4aa.github.io/)**. After three very successful workshops (**KIT** in 2023, **Salzburg** in 2024, and **DESY** in 2025) RL4AA'26 will be hosted as a **[LIV.INNO](https://livinno.org)** Workshop on Reinforcement Learning for Autonomous Accelerators by the University of Liverpool and Cockcroft Institute in the musically iconic port city of Liverpool.
 
-### We have an exciting workshop program lined up!
-
-- Two keynotes by RL experts
-  - Jan Peters (University of Darmstadt)
-  - The second speaker will be announced soon.
-- Hands-on RL challenge
-- Contributed talks
-- Posters
-- Introduction to RL
+RL4AA brings together the reinforcement learning and accelerator physics communities to share results, practical insights from the field, and the big questions ahead for real-world RL. Expect engaging **keynotes**, **invited and contributed talks**, a lively **poster session**, and a **hands-on coding challenge**.

 Please join us if you have worked in reinforcement learning or you are simply interested and would like to start! This workshop is intended to foster discussions and to start interesting projects together.
 
-Note also that this year’s workshop is organised in coordination with [5th ICFA Beam Dynamics Mini-Workshop on Machine Learning for Particle Accelerators (MaLAPA)](https://indico.cern.ch/event/1382428/overview) workshop at CERN (8 - 11 April). Both workshops are organised closely following each other such that you can attend both of them.
-
 We highly encourage every participant to submit a poster and share their work with other participants to have a lively exchange!
 
-Do not hesitate to share this invitation with your colleagues and contact the organizers at [email protected] for questions.
-
-We are looking forward to seeing you in Hamburg!
