+
+Fix the matcher modified by 4eab908c8679a797ac7016b77a93ee41bb11b0fc
+to deal with both strong and weak of FC_LANG as the same location in the score

+Subject: build-chain, replace INCLUDES directive by AM_CPPFLAGS
+
+As of automake-13.1 the INCLUDES directive is no longer supported.
+An automake run will return with an error.
+
+This changeset simply follows automake's advice to replace INCLUDES
+by AM_CPPFLAGS.

+Subject: Bug 63329 - make check fails: .. contents:: :depth: 2
+
+Add back FcHashGetSHA256DigestFromFile() and fall back to it
+when font isn't SFNT-based font because FT_Load_Sfnt_Table
+fails with FT_Err_Invalid_Face_Handle.
