+- V.7.0010.1000
+- Thu, 28 May 2020
+--------------------------------------------------------------------------------
+- New Features
+    o   Add support for MSN4600C.
+    o   ethtool reading of QSFP-DD EEPROM
+    o   Support of new wtchdog type with long timeout period.
+        New watchdog type is discovered by CPLD watchdog capability.
+        New timeout period can be longer than 32 or 255 sec as it was before.
+    o   Hottest thermal zone detection for thermal algorithm is done in
+        kernel driver.
+    o   Remove calculation of the hottest thermal zone and logic for changing
+        mode and policies for the thermal zones from user space script.
+        Algorithm provided by kernel will be used instead.
+    o   Representation of PSU FAN speed capabilities.
+
+- Bug fixes
+    HW Mgmt core:
+    o  Clean internal system names usage.
+
+- Known issues and limitations:
+    o  ethtool for QSFP-DD is working only in raw mode.
+    o  SN4700 PSU (Murata) sensors might be not available after insertion/removal.
+    o  PSUs inventory read via PMBus require the following packages:
+        - i2c-tools_4.1-1_amd64.deb
+        - libi2c0_4.1-1_amd64.deb
+    o  I2C Asic driver take up to 5 second to complete initialization. When
+	sending ADD even need to make sure to wait at list 5 second before
+	reset of ASIC.
+    o   Systems SN2010, SN2100, SN2410, SN2700 and SN2740 (and their
+        "-B" variants) require the following flag in kernel cmdline:
+        "acpi_enforce_resources=lax acpi=noirq".
+    o   Few bug fixes introduced in upstream kernel 4.19, whoever use older
+        v4.19 kernel then v4.19.58, should cherry pick the following commits:
+        - Fix wrong order in probing routine initialization:
+            d2d8f64012543898a0158b1fc5c07af3d41c89d8 (available in v4.19.49)
+        - Fix parent device in i2c-mux-reg device registration
+            c241f3fbfa1af86f572a92f2e4d708358e163806 (available in v4.19.58)
+    o   Kernel patch 4.9  #37 is available upstream from kernel 4.9.197 and
+        Kernel patch 4.19 #09 is available upstream from kernel 4.19.79.
+        - No need to apply these patches when working with these kernel versions
+          or above
+    o   This version requires FW version 29.2000.1886 or higher for spectrum-2
+	and  13.2000.1886 or higher for spectrum-1.
