In 2020, the London production, like Les Miz the year before, was essentially replaced by the staging of the touring production. "
Either you didn't see the recent touring production, or you haven't seen the London production. There were some changes (none for the better), but the Londond production did not switch to the touring production's staging.
The descending angel was replaced by an on stage statue, which resulted in some changes to the blocking and design of the proscenium. The chandelier was given a bigger redesign, and the lighting was switched to newer LED instruments; otherwise, things look mostly the same as they ever have. The big sin was cutting the size of the orchestra.
You can see how much, or little, was changed Here
