I know the delay for v5.00 is quite long. But I need to make some clarifications about Memtest86+ :
1. Memtest86+ was, is and will *ALWAYS* be a free, GPL software. This is important, especially since the original Memtest is now handled by a commercial company. Remember Redhat ? I really hope Passmark will not go that way, but who knows ?
2. Reliability is my #1 concern. False positive sucks. Really. Passmark added some really nice code to memtest86 in the past months, but their lack of beta-testing is really a massive issue. Memtest86 up to 4.3 was heavily bugged with a lot of bugs generating false positives. I don't want that for Memtest86+. That's why I have a massive pool of betatesters and nearly always existing hardware. Those tests need time. A lot of time. But that's mandatory. Memtest86+ 4.20 is still working as expected WITHOUT false positive issues. SMT features is a nice eye-candy feature, but it doesn't really improve the tool and generate a lot of potential issues. I did my own balance according to the betatesters.
3. Memtest86+ 5.01 is frozen, packaged and under betatesting. The 2+ years delay from 4.00 to 5.00 comes from big changes in the core structure that needed to be checked carefully. As soon as the 5.xx line will be released, updates will be MUCH faster.
