 Change Log
 ----------

+v3.19.7
+
+#369 Fixed time limited mining, --time-limit.
+Fixed a potential compile error when using optimization below -O3.
+
+v3.19.6
+
+#363 Fixed a stratum bug where the first job may be ignored delaying start of hashing
+Fixed handling of nonce exhaust when hashing a fast algo with extranonce disabled
+Small optimization to Shavite.
+
+v3.19.5
+
+Enhanced stratum-keepalive preemptively resets the stratum connection
+before the server to avoid lost shares.
+
+Added build-msys2.sh shell script for easier compiling on Windows, see Wiki for details.
+
+X16RT: eliminate unnecessary recalculations of the hash order.
+
+Fix a few compiler warnings.
+
+Fixed log colour error when a block is solved.
+
+v3.19.4
+
+#359: Fix verthash memory allocation for non-hugepages, broken in v3.19.3.
+
+New option stratum-keepalive prevents stratum timeouts when no shares are
+submitted for several minutes due to high difficulty.
+
+Fixed a bug displaying optimizations for some algos.
+
 v3.19.3

 Linux: Faster verthash (+25%), scryptn2 (+2%) when huge pages are available.
