+Subject: [PATCH] feat: support lpeg 1.1
+
+This changeset adds support for lpeg 1.1 which updated the lpeg.version from a function to a string.
+
+Therefore we have to check the type of the value.

+Subject: [PATCH] fix: fix lpeg version detection
+
+This changeset fixes the lpeg version detection to properly handle
+version > 1.1.
+
+The original fix did not properly parse the string because it search for
+the number to start the string instead of being part of the string.
