+- Update to version 3.10.5.1
+  * Runtime
+    + Restore the ability to set a default block buffer size using
+      the buffer_size parameter in the config file. This was lost
+      during refactoring in v3.9.
+  * GRC
+    + Add Python snipped hook point at "init before blocks", right
+      before blocks are instantiated.
+  * gr-audio
+    + Remove support for OSX 10.3 and earlier.
+  * gr-digital
+    + Make tags visible to subclasses of OFDM Frame Equalizer.
+  * gr-dtv
+    + Correct constant in DVBS2 Modulator.
+  * gr-fec
+    + Fix errors in Channel Construction AWGN
+  * gr-iio
+    + Fix IIO blocks, which were broken due to a build-time
+      dependency problem.
+  * gr-network
+    + Fix crash in UDP Source when buffer overruns.
+  * gr-qtgui
+    + Remove support for QWT 6.0 and earlier.
+  * gr-uhd
+    + Add async message port to USRP Source and publish overflow
+      notifications.
+    + Add bindings and example for RFNoC AddSub block.
