+Subject: [PATCH 4/5] BUG/MINOR: http: base32+src should use the big endian
+ version of base32
+
+We're using the internal memory representation of base32 here, which is
+wrong since these data might be exported to headers for logs or be used
+to stick to a server and replicated to other peers. Let's convert base32
+to big endian (network representation) when building the binary block.
+
+This mistake is also present in 1.5, it would be better to backport it.

+Subject: [PATCH 5/5] BUG/MEDIUM: connection: fix memory corruption when
+ building a proxy v2 header
+
+Use temporary trash chunk, instead of global trash chunk in
+make_proxy_line_v2() to avoid memory overwrite.
+
+This fix must also be backported to 1.5.
