+1. Kernal upgraded from 4.9.110-3deb9u6 (SONiC Release 201904) to 4.9.168-1+deb9u5 in this SONiC release. 


"Kernel" not "Kernal"

+# Feature List
+
+#### Build Improvements 
+This document provides functional design and specifications of BFD protocol as defined in RFC 5880, 5881, 5882 and 5883.BFD protocol defines a method of rapid detection of the failure of a forwarding path by checking that the next hop router is alive. The protocol will be able to detect the forwarding path failure in milliseconds depending on the actual configuration. 


This content (BFD) does not match the heading (Build Improvements). The topic here is the latter.

Same problem - cut and paste errors - pls fix

Also the HLD link just points to the folder - not very helpful - would be better to point to the actual HLD. Similar for the prior section also.

+
+#### Dynamic port break
+Ports can be broken out to different speeds with various lanes in most HW today. However, on SONiC, the port breakout modes are hard-coded in the profiles and only loaded at initial time. In case we need to have a new port breakout mode, we would potentially need a new image or at least need to restart services which would impact the traffic of the box on irrelevant ports. The feature is to address the above issues.


Suggest " However, on SONiC, before this release, the port breakout modes ...."

I guess you omitted the "before this release" part, but fair enough

Looks good ...

+
+#### Thermal control 
+Thermal control daemon has been added to monitor the temperature of devices (CPU, ASIC, optical modules, etc) and the running status of fan. It retrieves the switch device temperatures via platform APIs and raises alarms when the high/low thresholds are hit.It also stores temperature values fetched from sensors and thermal device running status to the DB.
+<br> Refer  [HLD Document](https://github.com/Azure/SONiC/blob/master/thermal-control-design.md) for more details.


Suggest to add more notes for this feature ... In addtion it provides the policy based thermal control and fan speed tunning in configuration, and we are able to customize and/or add the platform specific policies as needed.

Addressed it. Pls check and confirm.

Need add one feature - "PSU and FAN LED management", The PSU and FAN LED on switch will be set according to PSU and FAN presence and running status, for example if there is a failure happening to PSU or FAN, the corresponding LED will be set to red.
The related designs can be seen in #591 and https://github.com/Azure/SONiC/blob/master/thermal-control-design.md .
The PRs are:
sonic-net/sonic-buildimage#4437
sonic-net/sonic-mgmt#1580
sonic-net/sonic-utilities#881
sonic-net/sonic-platform-daemons#54
sonic-net/sonic-platform-common#83

@henry-ma: Addressed it. Pls check and confirm.

@kannankvs instead of mixing them into thermal control, I more incline adding two addtional features - "PSU and FAN LED management" and "PSU, thermal and FAN plugin extension".

"PSU and FAN LED management" - The PSU and FAN LED on switch will be set according to PSU and FAN presence and running status, for example if there is a failure happening to PSU or FAN, the corresponding LED will be set to red.
On new plugins for fan, thermal and PSU the PSU plugin was extended with voltage, current and power supported, and the fan and thermal plugins were introduced.

Changed. Pls check and confirm.

Another feature - New plugins for fan, thermal and PSU.
In this feature, PSU plugin was extended with voltage, current and power supported, and the fan and thermal plugins were introduced.
The PR is sonic-net/sonic-buildimage#4041

@henry-ma: Addressed it. Pls check and confirm.
