 # 20170621 bkw: fix build with -current's newer openjpeg, BUILD=2.
 # 20170122 bkw: update for 1.10a.
 
+# Notes for 1.18.0:
+# - This script can no longer build older versions, too many changes.
+# - Upstream *finally* supports building as a shared library, so I and
+#   all other distro packagers can stop patching it... except the
+#   shared lib is unversioned, which means upgrades would cause more
+#   breakage than they should. So there's still some trickery here to
+#   build a versioned solib.
+# - I've got rid of the STATIC=yes option and now only build shared libs.
+#   As a side effect, libmupdf-third is gone, but I've included a
+#   placeholder so stuff that links with it, will work without patching.
+# - gumbo (HTML parser) is now a hard dep. The source is bundled, so
+#   there's no need to create a new gumbo SlackBuild, but it does mean
+#   the mupdf shared lib has grown in size.
+# - mupdf-gl uses freeglut. The version we have in 14.2 is new enough to
+#   build with, but old enough that you can't copy text from mupdf-gl.
+#   So we build the bundled version here.
+# - API docs are now included in the package.
+# - Now using upstream's icons, including scalable SVG.
+# - Add missing doinst.sh
+# - There's now the option to build with tesseract and leptonica,
+#   but it's disabled in this script. I have yet to get it to
+#   actually *do* anything other than fail to build (when using
+#   upstream's tesseract/leptonica forks) or complain about being
+#   unable to load eng.traineddata (using SBo tesseract/leptonica,
+#   and yes eng.traineddata is fine). Until I work out what's wrong,
+#   or upstream releases a new version, this script doesn't support
+#   building with tesseract. Don't contact me about this before March
+#   1, 2021, unless you actually have a patch that fixes it. After
+#   that, if this message is still here, feel free to remind me to
+#   revisit it.
+# - Slackware 14.2's libcrypto (from openssl) is too old for mupdf,
+#   and there's no bundled souce for it. So currently mupdf is being
+#   built without libcrypto. Hope that's OK.
