I know YFULL service since maybe 2015, after I started more research in yDNA direction. At that time, I knew that it’s only yDNA tree representation, but I didn’t pay much attention how they do. Later on, 2015-2017, it becomes more popular, and they gave ability to upload DNA raw files to the system and for the dedicated payment they provide more detailed results. I ordered BigY test from FTDNA Aug-2017, but it was delivered only in Nov-2017. And I didn’t have BAM file from FTDNA, which was needed as input file for YFULL. Fortunately, YFULL implemented VCF file analysis, and I was able to upload it and to receive some preliminary results. Jan-2018 I ordered YFULL account based/using VCF (49$), and I knew, that later on I will be able to upgrade with free upload of BAM file. May-2018, FTDNA finally renewed BAM file generation. I requested, and after some time I receive BAM file. Then I uploaded to yfull, so my account upgraded. Jun-2018 got some results from YFULL in Upgrade section. But in fact not so much new info. Anyway, YFULL looks very active service, then have recently published v6.03.41 (Jul-2018), which looks to be following SemVer, and I expect their updates more frequent now.
