+- Update to 21.3:
+- Changes for 21.3:
+ * http://erlang.org/download/OTP-21.2.7.README
+ * Erlang/OTP 21.3 is the third service release for the 21st major release
+   with improvements, as well as a few features
+ * Highlights
+ * Kernel: The standard logger handler, logger_std_h, now has a new internal
+   feature for log rotation. For full information see the documentation.
+ * SSL:The Reason part of the error return from the functions connect and
+   handshake has a better and documented format. This is a potential
+   incompatibility. See the documentation.
+   Refactoring of state handling has improved the TLS application data
+   throughput and reduced CPU overhead
+   Code optimizations has reduced CPU load for encryption/decryption,
+   especially for Erlang's distribution protocol over TLS
+   Now supports active N
+ * Erl_interface: Support for plugin of a user supplied socket implementation has been added.
+ * OTP:The HTML reference documentation now shows the OTP version where
+   modules and functions were first introduced. Versions of OTP older than R13B04 is not shown in the reference
+   documentation
+ * For a full list of details see:
+   http://erlang.org/download/otp_src_21.3.readme
+
+- Update to 21.2.7:
+- Changes for 21.2.7:
+ * http://erlang.org/download/OTP-21.2.7.README
+ * erts, otp: Fixes of install/release phase in build system.
+   -- The source tree was modified when
+   installing/releasing and/or applying a patch.
+   -- Some files were installed with wrong access rights.
+   -- If applying a patch (using otp_patch_apply) as
+   another user (except root) than the user that built the
+   source, the documentation was not properly updated. 
+ * erts, kernel: Setting the recbuf size of an inet socket the buffer is
+   also automatically increased. Fix a bug where the auto
+   adjustment of inet buffer size would be triggered even
+   if an explicit inet buffer size had already been set.
+ * erts: Reading from UDP using active true or active N mode has
+   been optimized when more packets than specified by
+   read_packets are available on the socket. 
+ * erts, kernel:  Setting the recbuf size of an inet socket the buffer is
+   also automatically increased. Fix a bug where the auto
+   adjustment of inet buffer size would be triggered even
+   if an explicit inet buffer size had already been set.
