The rules for advancement to the onsite finals of TCO 2019 Algorithm have changed from those for TCO 2018:
This page claims there are "three (3) ways to advance to the Onsite Finals"!
The first way to advance is to take part in SRMs. There are four three-month Online Stages, during which every positive score in an SRM counts towards a global ranking. The best competitor in each Online Stage advances to the onsite finals directly, with the next 10 competitors advancing to Online Round 4 (which is the final qualification round).
The other two ways stay the same. The best 10 competitors (used to be 14 though) advance from Online Round 4, and the best 2 competitors advance from Online Wild Card Round.
The changes seem to be big enough -- and already relevant, since SRM 736 on August 15 (in two days from now) already counts towards Online Stage 1. However, apart from TCO 2019 website I've only seen this information in Topcoder weekly newsletters, and I believe many people have missed it.
