+- Update to version 3.7.13.4
+  * Fix Boost 1.67 linking issue
+  * Logging - fixed issues where messages weren't properly written
+    to stdout/stderr due to incorrect strings
+  * gr-analog - `fmdet_cf`'s derivative coefficients were wrong.
+  * gr-blocks - `skiphead` used to incorrectly handle tags, 
+    now properly shifts
+  * gr-digital - `qa_packet_format`: Unit test used to potentially
+    lock up due to incorrect conditionals
+    - `clock_recovery_cc`, `crc32_bb`: Accessing the `[0]` element
+      of an empty vector is UB, even if you don't use the result
+      afterwards.
+  * gr-fec - `polar_encoder`/`_common`: Fixed multiple out-of-bound
+    accesses due to insufficient vector length checks
+  * gr-filter - `fft_filter`, `filter_delay`: Accessing the `[0]` 
+    element of an empty vector is UB, even if you don't use the
+    result afterwards.
+- Patch missing_libraries.patch modified
