+Builder (/build):
+- Simplify the upload of the build context
+- Simply stream a tarball instead of multipart upload with 4 intermediary buffers
+- Simpler, less memory usage, less disk usage and faster
+
+.. Note::
+The /build improvements are not reverse-compatible. Pre 1.3 clients will break on /build.
