For April, it looks like these are mostly modern versions. I took out all the no-SSE2 entries and analyzed them. Here are the most common version numbers with percentages (of all non-SSE2 entries): 28. , 60.1 27. , 7.3 29. , 7.1 12. , 2.1 10. , 1.3 3.6, 1.3 11. , 1.2 3.6, 1.2 26. , 1.1 Cheers, Matthew _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
