EA and Respawn have released a new free update for Jedi: Fallen Order. Sadly not a story DLC but the update includes:
Meditation Training mode hub giving access to two new game modes: Combat Challenges and Battle Grid
New Journey + mode which unlocks new cosmetics, such as Inquisitor Uniform for Cal, as well as a red kyber crystal and the Protection and Defense I & II lightsaber sets
improved accesibility features, overall responsiveness of the gameplay and fixed combat input irregularities
Also, it seems that there will be a sequel to the game too.
