CHANGELOG_LATEST.md

@@ -16,6 +16,8 @@ This release is based on the latest Espressif/Arduino core version 3. It brings
 - cleaner MD5 and firmware uploading in WebUI [#3222](https://github.com/emsesp/EMS-ESP32/issues/3222)
 - pc0Flow in l/min [#3224](https://github.com/emsesp/EMS-ESP32/issues/3224)
 - remove HA config for excluded entities [#3229](https://github.com/emsesp/EMS-ESP32/issues/3229)
+- `show system` reports the Ethernet status on boards with a PHY, so a failed initialisation or a link that never came up is visible instead of Ethernet being omitted completely. Also shows the loop task's lowest free stack, to help diagnose reboots
+- new Application Setting "Automatically check for firmware updates", off by default. When enabled EMS-ESP asks emsesp.org for the latest version once a day on its own, otherwise it only asks when the WebUI wants to show it, so an unattended system never contacts emsesp.org
 
 ## Fixed
 
@@ -28,6 +30,9 @@ This release is based on the latest Espressif/Arduino core version 3. It brings
 - 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)
 - solar module switches [#3223](https://github.com/emsesp/EMS-ESP32/issues/3223)
+- possible crash when the WebUI asked for version information while the versions.json refresh was rewriting the cache from the main loop task
+- HTTP client could write past a fixed 64 byte buffer when a URL had a hostname of 64 characters or more, could busy-spin for the whole read budget if the socket reported bytes it wouldn't return, and buffered responses without any size limit
+- the "Ethernet clock mode (GPIO16/17) conflicts with PSRAM" error was never logged because Ethernet had already been skipped by the time the check ran
 - heat limit entities (`maxheatcomp`, `maxheatheat`, `dhw.maxheat`) read as unknown on heat pumps with an auxiliary heater larger than 9 kW - `enum_maxHeat` was missing the 12 kW and 15 kW steps
 
 ## Changed
@@ -43,4 +48,6 @@ This release is based on the latest Espressif/Arduino core version 3. It brings
 - set `None` for undefined values in HA `val_tpl`
 - changes in WebUI - remove multiple calls systemInfo endpoint, Vewrsion pages checks for internet connection [#3195](https://github.com/emsesp/EMS-ESP32/pull/3195)
 - multiple optimization in network, power down WiFi when Ethernet and WiFi nosleep is instant when selected [#3213](https://github.com/emsesp/EMS-ESP32/pull/3213)
+- TLS buffers (~17KB per HTTPS request) are taken from PSRAM on boards that have it, instead of fragmenting the internal heap
+- failed versions.json fetches back off from 5 up to 160 minutes instead of retrying every 5 minutes, as each attempt blocks the main loop for as long as the DNS, connect and read timeouts allow
