# - Updated README & slack-desc to mention XPS and CBZ
# - Fix the man pages slightly
+# Modified 20140224 by B. Watson (yalhcru@gmail.com):
+# - backported security fix for CVE-2014-2013. I will be upgrading this
+# build to mupdf-1.3, but it'll take more work than I currently have
+# time for:
+# + mupdf's internals have changed, will have to redo my patches
+# + it depends on openjpeg 2.0 which SBo hasn't got yet. 2.0 uses an
+# incompatible API, so an openjpeg 2.0 SlackBuild would require
+# updates for everything that depends on it.
+# + zathura-pdf-mupdf will need updating (mupdf's API has changed)
+# + probably all the other zathura-* builds will need updating to
+# be compatible with new zathura-pdf-mupdf
+# The security fix is needed now, it's a tiny patch, and shouldn't have
+# to wait on all that other stuff.
