I've updated all of them to be mostly V1.47n-compatible (the remaining issues are due to things that need to be fixed in the player, rather than needing to be fixed in the NXPs; except that I didn't make the effort to re-test the levels. The primary issue is that most of the special graphics levels don't work, because the VGASPEC files are still in the older format which V1.47n currently has no support for).
For most of the packs the only change is that they've been marked as "compatible with both V1.43n-F and V1.47n" (and the old NXPs would work, apart from giving a warning about possible compatibility issues). The exceptions are Orig and Extra; the existing NXPs will not work properly on V1.47n.
(As this implies, these new updates are still 100% compatible with V1.43n-F too.)
Two of these haven't been updated:
NeoLemmix Introduction Pack - It will be updated, but more changes are needed here than simply "rebuild with a new toolkit version and maybe tweak a couple of settings".
Copycat Lemmings - This pack relies on Cheapo Mode which is no longer supported in V1.47n, as such, this pack cannot be updated. You'll need to use V1.43n-F to play this one.
