I was looking up sequences on NCBI GenBank from an equine gene, and stumbled upon the fact that since december 2024 there are new versions of gene sequences based on a new reference genome of the horse. Until recently, all genes I found were based on the EquCab3.0 project, but now new versions are based on 'TB-T2T (GCF_041296265.1)' which is apparently the new reference genome assembly for the horse. I can not find any publications about this though, and when I further read the assembly comments I found this:

'This is the maternal pseudohaplotype assembly created from the genome sequence of a female mule (isolate M_4285; BioSample SAMN40588552) resulting from a cross between a male Equus asinus (isolate D_3611; BioSample SAMN42823850) and female Equus caballus (isolate H_3958; BioSample SAMN42823849).'

Even though they say the breed of this assembly is 'Thoroughbred'. I don't know if this assembly is correct or if I should trust this, as they say in the comments it is the genome of the mule but use it as a reference genome for the horse.

Should I just keep using the sequences based on EquCab3.0 or use the new ones?
