2.2.2

Enhancements (could be also seen as bug fixes):

• #44: increase Telegram polling period to 20 s;
• #45: get rid of Ticker-based timers;

Altogether this should reduce the probability of spontaneous reboots of the receiver module.

Internal / refactoring:

• updates in versions of JLed, AceButton and ArduinoJson libraries.

2.2.1

Enhancements:

• add bullets to Telegram's /status for better readability (#43).

Bug fixes:

• malformed Telegram's /status message if no mailbox registered (#40);
• remote module uptime not always displayed (#41);
• fixes in Telegram configuration and communication (#42).

Internal / refactoring:

• avoid unintentional masking of a class variable (included in #42);
• updates in versions of ESP Core and ArduinoJson.

2.2.0

Features:

• order mailboxes list in web and Telegram (#18);
• allow acknowledgements of individual mailboxes. Now there are separate Ack buttons per mailbox on the web, and Telegram commands /ack and /status take mailbox ID as parameter (#20);
• report remote module uptime (on a best guess basis, as it is not possible to be 100% sure here) (#13). Local module uptime will now also be reported in Telegram's /status;
• move Telegram credentials and Google endpoint settings from compile-time to run-time using a new web page /conf (#15, #31). It is now also possible to enable / disable these services dynamically;
• suppress special treatment of Google Assistant in emulation mode (#15);
• embed the web site icon and remove the need to pre-load it on flash (#6);
• report low battery condition even in presence of a higher priority alarm (#16);
• treat timeout on receiver as a missed message and adjust radio link quality appropriately (#9);
• display mailbox label on its individual page;
• minor improvements in web navigation display.

Bug fixes:

• fix receiver spontaneous reboots when remote peers such as Telegram are down (#3);
• fix potential junk in the app log on boot if time synchronization is delayed (#29);
• fix bad formatting of error message in the app log if multiple issues have been detected in the incoming packet (#19).

Internal / refactoring:

• migrate to ESP Core v3.1;
• migrate to the latest versions of libraries JLed and ArduinoJson;
• compile Google Assistant support in unconditionally, as it is a low-cost feature (#32);
• convert hardcoded battery change weighting coefficient into a compile-time constant;
• move mailbox comparison operator to the base class and add more comparison methods;
• make some printing methods const;
• move DS-System library into src/ folder, so that it is no longer offered for editing in Arduino IDE;
• move majority of pics from the source code repo to the Wiki repo.

2.1.1

Bug fix release. Changes:

• fix a boot loop on a blank local module with Telegram support enabled (#17);
• do not report door bouncing on Google Home (second try) (#11).

2.1.0

Changes:

• adjust battery coefficients to be closer to 0-100% (#14);
• report door opening duration in the application log (#12);
• do not report door bouncing on Google Assistant (#11);
• only check for mailbox absence if time has been synchronized;
• port to ESP Core v3;
• port to DS-System v1.1, bringing, in particular, new application log interface. Periodic timers now rely on DS-System too;
• remove dependency on LinkedList library (#10); update other dependencies.

2.0.0

Changes:

• remove debug information from the application log (issue #2);
• add a pointer to GitHub;
• update of WiFiManager dependency to 0.16;
• documentation updates.

2.0.0-beta.2

Changes:

• fixed mailbox initialization from disk in local module
• tested on real hardware
• updates of dependent libraries to the latest releases
• documentation updates

2.0.0-beta.1

First public release. Versions 0.x and 1.x were developed in a private repository. Some refactoring was made for publishing; hence, silly bugs are not impossible. V2 will stay in beta until fully tested on prod hardware.
