+
+### Libraries
+
+- Better connection handling in ESP8266WebServer.
+  The server now sends Content-Length and Connection: close headers,
+  then waits for the client to disconnect. By not closing the connection
+  actively, server avoids TIME_WAIT TCP state, and TCP stack is able to 
+  release the memory immediately, without waiting for 2xMSL period. 
+  If the client doesn't disconnect in 2000ms, the server closes the connection
+  actively.
+- Add Hash library, which has a function to calculate SHA1 hash.
+- SD, Adafruit_ILI9341, and OneWire libraries are now bundled.
+- Fix incorrect sector calculation in EEPROM library.
