+- Update to 1.3.4
+  * perf: faster speed (especially decoding speed) on recent cpus
+    (haswell+)
+  * perf: much better performance associating --long with
+    multi-threading
+  * perf: better compression at levels 13-15
+  * cli : asynchronous compression by default, for faster
+    experience (use --single-thread for former behavior)
+  * cli : smoother status report in multi-threading mode
+  * cli : added command --fast=#, for faster compression modes
+  * cli : fix crash when not overwriting existing files
+  * api : `nbThreads` becomes `nbWorkers` : 1 triggers
+    asynchronous mode
+  * api : compression levels can be negative, for even more speed
+  * api : ZSTD_getFrameProgression() : get precise progress
+    status of ZSTDMT anytime
+  * api : ZSTDMT can accept new compression parameters during
+    compression
+  * api : implemented all advanced dictionary decompression prototypes
