ESP-WROOM-02 Hardware and Firmware Release Information

[lucyelectric]

Originally posted in error in the General Discussion Forum, so now posted here hopefully in the correct Forum.

We have used many ESP-WROOM-02 WiFi Modules since about 2015, (approx 1500+ modules).
(I've be informed by chegewara that this module is a ESP8266, thank you).

Recent batch purchases have revealed a new style module package (well at least the printing on the can is quite different) and also what we believe to be new Firmware revision being reported.

The Firmware version on earlier units is reporting as: 1.5.3.0
On the newer purchased modules we are seeing a version of 1.6.2.0 being reported.

We have some connection issues with the newer module, where can I find details of the Firmware release notes detailing the Firmware changes made.
Also I would like to be able to confirm if there have been any Hardware changes to the module.

Attached: I have attached 2 photos, for the older style and newer style module packages.

Many thanks for your help in advance,
Phil.
