-## [3.8.3]
+## [3.9.0]
+
+This release is based on the latest Espressif/Arduino core version 3. It brings in many memory and performance optimizations. Note it does require the user to manually migrate settings from 3.8.x to 3.9.0.

 ## Added

- KM300 at address 0x4A [#3084](https://github.com/emsesp/EMS-ESP32/issues/3084)
+- user-requested LED blink [#3063](https://github.com/emsesp/EMS-ESP32/issues/3063)
+- Commands Service that can be called via MQTT or API or used in the Scheduler Service
+- option to disable factory reset [#3150](https://github.com/emsesp/EMS-ESP32/issues/3150)
+- TLS support with 4MB boards without PSRAM
+- added eth_10mbit to Network Settings, which forces 10BASE-T half-duplex & autonegotiation off, halving the PHY’s power draw. It’s off by default as it will cause issues on managed switches with a port forced to 100Mb [#3213](https://github.com/emsesp/EMS-ESP32/pull/3213)
+- cleaner MD5 and firmware uploading in WebUI [#3222](https://github.com/emsesp/EMS-ESP32/issues/3222)

- start scheduler after customEntities, delay scheduler loop after startup, handling of `system/restart` command [#3146](https://github.com/emsesp/EMS-ESP32/issues/3146)

- water module SM100/200 as dhw1/dhw2 [#3164](https://github.com/emsesp/EMS-ESP32/issues/3164)
+- shunting yard show json
+- `system/sendmail` called from a Command or the Scheduler computed its value twice, which stripped the quotes from literal text and then failed on characters like `!`. Also shunting yard treated a `?` inside a quoted string as a ternary, so text like `"too hot?"` returned nothing
+- memory leak when using different timezones for ems-esp and thermostat[#3184](https://github.com/emsesp/EMS-ESP32/issues/3184)
+- LED stayed off on a healthy system when "Disable LED" was unchecked
+- Ethernet MAC address changed with the new SDK, breaking DHCP reservations (currently disabled)
+- "IPv4 nameserver" showed an IPv6 address when IPv6 was in use
+- HA Discovery warning on Uptime after EMS-ESP boot due to NTP not ready
+- hc/control setting for UI800 thermostats [#3181](https://github.com/emsesp/EMS-ESP32/discussions/3181)
