1. Added Cross-Origin Resource Sharing (CORS) field in the HTTP-header in the GET repsponse;
2. The HTTP timeout is 10 sec;
3. It is fixed the issue with SNMP traps sending during some rare cases (bug fixing);
4. Enabled simultaneous access via HTTP web server and HTTP XML/JSON request without interruption of the web session;
5. Implemented current_state.xml and current_state.json
    - Command for setting single output: P31...P38=0/1/2 и P51...P58=0/1/2 (0-low level, 1-high level, 2-invert)
    - Command for settings whole output port: P3=0...255 and P5=0...255
6. Implemented device name setting:
    - Device Name in HTTP General Settings
    - OID .1.3.6.1.4.1.42505.9.1.33.0 for SNMP
7. New MIB file format - validated to level 6;
8. "Remote IP to Ping" can be changed from web server (bug fixing);
9. Small fluttering during initialization of P3/P5 (in case of outputs) is fixed.

1. Added Cross-Origin Resource Sharing (CORS) field in the HTTP-header in the GET repsponse;
2. Enabled simultaneous access via HTTP web server and HTTP XML/JSON request without interruption of the web session;
3. "Multiple Access" option in HTTP/XML/JSON Settings is hidden (always '1'); 
4. New MIB file format - validated to level 6;
5. In the snmp SNMP traps it is added second variable binding - the description of the I/O (OctetString);
6. It is fixed the issues with SNMP traps sending during some rare cases (bug fixing);
7. IMPORTANT!!! The HTTP buffer used for HTTP GET requests becomes from 117 to 101 bytes. This must be considered for applications with long HTTP requests;
8. Added additional short HTTP commands for current_state:
- Digital Output: DX (192.168.1.100/current_state.xml?pw=admin&D1=1)
- Pulse: PX (192.168.1.100/current_state.xml?pw=admin&P2=20)
- Counter: CX (192.168.1.100/current_state.xml?pw=admin&C3=0)
- PWM: WX (192.168.1.100/current_state.xml?pw=admin&W1=0)

1. Added Cross-Origin Resource Sharing (CORS) field in the HTTP-header in the GET repsponse.
2. Enabled simultaneous access (with unchecked Encrypt Password) via HTTP web server and HTTP XML/JSON request without interruption of the web session.
3. "Multiple Access" option in HTTP/XML/JSON Settings is not anymore active (assumed to be always '1' (enabled)).
4. The HTTP timeout is 10 sec.
5. Added Date/Time fields to XML/JSON.
6. Fixed a bug causing DAEL script to stop unexpectedly (Ecxecution Error) at certain moments. Added check sum to each DAEL instruction. If a reading error is detected, they are done up to 19 more EEPROM readings (through 250 ms). If all the 20 sequential readings are not successfull, then Execution Error occures.
7. If Execution Error occures, it is possible to restart the DAEL program with "Run" button from Web pages Program Editor/Control.
8. Added Execution Errors counter in home page and program.xml/program.json. It is stored in EEPROM. It indicates how many EEPROM error readings the PLC managed to fix.

1. Enabled simultaneous access (with unchecked Encrypt Password) via HTTP web server and HTTP XML/JSON request without interruption of the web session (bug fixing);
2. current_state.xml/current_state.json respone time is optimized (decreased).

1. Added Cross-Origin Resource Sharing (CORS) field in the HTTP-header in the GET repsponse.
2. Enabled simultaneous access (with unchecked Encrypt Password) via HTTP web server and HTTP XML/JSON request without interruption of the web session.

4. In the snmp SNMP traps it is added second variable binding - the description of the I/O (OctetString).
5. New MIB file format - validated to level 6.
6. It is fixed the issues with SNMP traps sending during some rare cases (bug fixing).
7. The HTTP timeout is 10 sec.
8. Changed the documentation link in the home web server

Good luck and stay healthy!
