Over at FTDNA they announced that R1b-L754 has split because of a Tajik man from Sughd Province. If I am understanding them correctly the split must have happened in Central Asia. This clade is Pre-M269 and indirectly linked to the Yamnaya/Corded ware people.

Y-DNA haplogroup R-L754, also known as R1b1, has just been split.

The split is based on the DNA test results of a Tajik man from a 2022 study. His DNA adds a new data point in the migration story of millions of men. A majority of men in Europe are descendants of these R1b1 genetic ancestors. Their Y-chromosome signature spread into Europe from Central Asia during the Bronze Age.

The Tajik man is from the Sughd Province in the Republic of Tajikistan. Tajiks are a Persian-speaking Iranian ethnic group native to Central Asia. The new Y-DNA haplotree structure is R-L754 (3 SNPs) > R-L761 (17 SNPs). The split is estimated to have happened around 16,500 BCE.

The Discover reports will be updated with this new information next week.

The new Tajik man is R1b-L761 and the split is just under Villabruna 1. So, we can officially exclude Villabruna 1 as an ancestor to M269. Also, the split must have taken place about 16500 years ago.
