+- Update to version 3.10.9.1
+- Changed
+  * Project
+    + Python minimum version is now 3.7.2, vs 3.6.5, to support type
+      hints.
+    + Add tox.ini, so that editors use the same formatting as
+      github CI.
+    + Use pointers to pass s32fc arguments to VOLK in gr-blocks,
+      gr-digital, and gr-dtv to avoid undefined behavior. The fix
+      is conditional on VOLK 3.1.0, which add a new supporting
+      function.
+  * Runtime
+    + Disallow None for pmt_t arguments in Python.
+    + Support spdlog installations with internal or external libfmt.
+  * GRC
+    + Use text labels to specify types for block parameters,
+      instead of background colors which were difficult to
+      read/remember.
+    + Enable setting of documentation URLs, relative or absolute in
+      yaml. This allows OOTs to use the documentation link in the
+      block parameter dialog.
+    + Disallow use of block ids that are Python keywords and 
+      "gnuradio".
+    + Add type annotations in some places (required bump to
+      Python 3.7.2).
+    + Use C version of YAML loader (yaml.CSafeLoader) for
+      better performance.
+    + Connections may have properties for supported connection
+      domains. This feature was added for RFNoC connections. Standard
+      stream and message connections do not support this feature,
+      but they may in future versions.
+    + Check grc file version. The above feature required a
+      version bump to "2". Where no connection properties are
+      used, version "1" is still emitted. Note that previous
+      versions of GRC do not check for file version. RFNoC
+      flowgraphs with connection properties will fail to load
+      in previous versions as a result.
+    + Fix bug where an impressive number of backslashes were
+      added to some filenames.
+  * gr-dtv
+    + Read expected data as little-endian
+  * gr-fec
+    + Add FEC_API to CCSDS Reed-Solomon functions so they can be
+      used by OOTs.
+  * gr-qtgui
+    + QT GUI Msg Push Button: add a callback for Message Value to
+      allow it to change at runtime.
+  * gr-uhd
+    + RFNoC Rx-Streamer: Add start stream options
+    + Add back-edge property to RFNoC connections
+  * Build system and packaging
+    + Use utf-8 encoding when writing files in gr_python_install.
