+Toolchain development and fixes
+-------------------------------
+
+Mattia uploaded [[!pkg dpkg]]/1.18.10.0~reproducible1 to our [exeprimental repository](https://wiki.debian.org/ReproducibleBuilds/ExperimentalToolchain).
+He covered in details the reason for the upload and the changes in
+[a mailing list post](https://lists.alioth.debian.org/pipermail/reproducible-builds/Week-of-Mon-20160919/007119.html).
+
+The most important change is the incorporation of the improvements Guillem Jover
+(dpkg maintainer) did to the .buildinfo generator.  This is also in the hope to
+somehow speed up the merge in proper dpkg.<br />
+One of the most relevant change from before is that now .buildinfo generated from
+binary-only builds will not include anymore the hash of the .dsc file in Checksums-Sha256
+as documented in the [specification](https://wiki.debian.org/ReproducibleBuilds/BuildinfoSpecification#buildinfo_field_descriptions).
+Even if it is considered important to include a checksum of the source package
+in .buildinfo, storing it that way breaks other assumptions (like that
+Checksums-Sha256 contains only files part of that are part of a single upload,
+wheras the .dsc might not be part of that upload), thus we look forward for
+another solution to store the source checksum in .buildinfo.
