* install-mk (MK_VERSION): 20260704
2026-07-03 Simon J Gerraty <sjg@beast.crufty.net>
* dirdeps.mk: make use of alternation support in latest bmake
when setting .MAKE.META.IGNORE_FILTER so we can get both
Makefile.depend* and *.mk to make cache out-of-date.
2026-07-02 Simon J Gerraty <sjg@beast.crufty.net>
* meta2deps.py: detect corrupted filemon data on Linux,
caused by lost newlines.

rather than just .new
2026-05-21 Simon J Gerraty <sjg@beast.crufty.net>
* meta2deps.{py,sh}: skip pathnames with spaces - not worth the pain.
