Security Updates
- NMOS HTTP server - request: Limit the maximum URL size to 8192.
- NMOS HTTP server - request: Disable TRACE method.
- TCP timestamps deactivated
- disabled unnecessary SSH ciphers:
      a. MD5_HMAC disabled
      b. 3DES disabled
      c. CBC disabled
      d. 96_HMAC disabled

Changes
- rp filter for Multicast is now de-activated per default -> Multicast packets from different subnets are now accepted by default
- improved Interface binding for redundant NMOS connections

Bugfixes
- Improvements for IGMP re-join after link loss
- Bugfixes for NMOS:Change of Payload ID, Framze size, audio format, Channel Number, PTP GMID, Sample rate are now reflected in SDP and NMOS data structure
- Bugfix for SDP parser when receiving SDP over SAP
- Bugfix for TCP keep alive sockets that were not closed correctly in some situations


********************************
HW 0.29 / SW 1.02.3 (13.08.2024)

- SDP Import via file and copy/paste
- HTTPS Announcement added to MDNS

Changes
- SDP attribute "ptime" is now represented with 3 digits after decimal point
- Improved parameter check for configuration data
- NMOS configurable to use both NICs or only one
- Improved robustnes of SDP parser

Bugfixes
