They've deleted the references to GGLfL though. It now says:

Lifetime Tier thresholds from 1 April 2025:
Gold for Life: 550,000 Lifetime Tier Points

and

Your proportional progress towards the next Lifetime threshold will be carried over. For instance, if you’ve collected 50% of the Lifetime Tier Points required for Gold for Life, your new balance will equal 50% of the new threshold.

For example:

Current balance – 17,500 Lifetime Tier Points
This will be converted to – 275,000 Lifetime Tier Points

Or , if you're already a Gold for Life Member, your Lifetime Tier Point balance will be proportionally transfered, or set to at least 550,000 tier points, whichever is higher.

Here’s an example:
Current balance – 50,000 Lifetime Tier Points
This will be converted to – 750,000 Lifetime Tier Points

It did initially say that the threshold for GGLfL was 1,500,000 'new' TPs, but they've deleted this in a subsequent edit.
