Version Description
V7.10.0
  • corrected reduced performance in the loopback interface
  • added debug configuration for Event Recorder
  • added sendmsg function to BSD sockets
  • corrected netTCP_GetSocket and netUDP_GetSocket functions to return netError code, if no free sockets are available, instead of calling net_sys_error handler
  • corrected potential failure to start network tick timer in RTX5 environment
  • added implicit binding to BSD sockets in connect and sendto functions
  • updated bind function to support dynamic ports (bind to port 0)
  • added recvmsg function to BSD sockets
  • added dynamic port range settings in TCP and UDP sockets
  • improved Ethernet debugging
  • added Virtual LAN support in Ethernet interface (VLAN)
  • updated Ethernet interface for reading the MAC address from the driver, if a unique MAC address is available in the driver
  • updated netIF_SetOption and netIF_GetOption functions to accept a possibly non-aligned buffer, when 16-bit or 32-bit option is passed in the buffer
V7.9.0
V7.8.0
  • corrected quoted-printable encoding for the character '=' in netSMTPc_SendMail function
  • documented possible return codes for Network API functions
  • changed return code netError to netFileError where appropriate in TFTP client
  • corrected netSMTPc_SendMail functionality, if the requested attachment does not exist, the function fails with error code netFileError, rather than send a dummy attachment
  • corrected a failure in netSMTPc_SendMail function, when sending an email with a large attachment
  • added netUninitialize function to uninitialize the Network component
V7.7.0
  • added SMTPS Client for secure emails (SMTP over SSL/TLS) using mbed TLS library
  • corrected notifications in the Ethernet interface to send gratuitous ARP for each change of the IP address
  • corrected poor performance on the HTTP server, when opening large files
  • corrected thread lock issue in accept function of BSD sockets, if called from a different thread in blocking mode
  • improved robustness required for Achilles level 1 certification
  • added transmit frame buffering, if MAC address in ARP cache is not resolved (first call to netUDP_Send function does not fail anymore)
  • replaced deprecated "__declspec" compiler directives with "__attribute__" directives
  • updated SMTP client configuration for backward compatibility
  • some optimizations of Network Core and services
  • added netSMTPc_SendMail function, which runs in blocking mode
  • added support for multiple email recipients (To, Cc, Bcc)
  • added support for email address friendly names in SMTP client
  • added configurable character encoding to support non ascii characters in SMTP client
  • added support for email attachments in SMTP client
V7.5.0
  • added netDHCP_SetOption function to change DHCP client options at runtime (for example DHCP Client-identifier option)
  • added support for IPv4 fragmentation and reassembly
  • added configurable MTU parameter for all network interfaces
  • extended netIF_SetOption to change MTU parameter at runtime
  • added netETH_SendRaw and netETH_ReceiveRaw functions to support implementing ethernet protocols by users
  • added netDNSc_ClearCache function to clear the DNS cache at runtime
V7.4.0
  • corrected HTTPS Web server problem, upload files limited to small files
  • corrected problem of data loss in BSD stream sockets (TCP), which was caused by a traffic congestion on high-latency networks
  • corrected FCARM file converter processing of regular expressions in java script (js) files
  • corrected FCARM filename encoding to use slash '/' folder separator character (allows saving resource files in virtual subdirectories)
  • library made RTOS agnostic, OS calls are from external functions which are compile time available
  • added RTOS configuration files for CMSIS-RTOS and CMSIS-RTOS2
  • added netIF_SetDefault function to dynamically change default interface at runtime
  • added netHTTPs_SetRootPath, netFTPs_SetRootPath and netTFTPs_SetRootPath functions to change root folder at runtime
  • corrected PPP_ACCM option negotiation in PPP interface, which caused connectivity issues with some GSM modems
V7.3.0
  • added event recording debug library variant
V7.2.0
  • corrected DHCP client to accept DHCP OFFER message, if source IP of relay agent is 0.0.0.0
  • corrected return status in netUDP_Send function to indicate an error, if the packet is dropped while sending UDP packets back to back
  • improved compatibility with ARM Compiler 6
  • expanded buffer size for the modem response string from 40 to 128 bytes
  • corrected infinite receive timeout in recv function, when BSD stream socket is in server mode
  • simplified and optimized processing user command in Telnet server user interface
  • added decoding of URL-encoded file/path information in HTTP server (ie. space character in a resource filename)
  • optimized sending emails to generate less packets in SMTP client
  • corrected thread deadlock in gethostbyname function, if netDNSc_GetHostByName function is called at the same time
V7.1.0
  • added HTTPS Server for secure communication (HTTP over SSL/TLS) using mbed TLS library
  • corrected link disconnect problem in netPPP_Close and netSLIP_Close functions
  • updated HTTP, FTP, Telnet and TFTP Server start/stop control functions to blocking mode (function is completed after the server is running/has stopped)
  • corrected problem of FTP Server not working with USB Host file system
  • corrected BSD receive functions to return BSD_ERROR_CLOSED, if the connection is unexpectedly closed in blocking mode
  • corrected serial communication problem on high-speed devices using PPP or SLIP interface
  • added osThreadYield in Network core main loop (cooperative multithreading)
  • added BSD socket event notification for mbed-client integration
  • added access to modem response string in modem driver
  • corrected low TCP performance problem when using only netTCP_Send and no network services
V7.0.0
  • corrected connectivity problem in PPP interface running in server mode
  • added support for relay agents in DHCP client (server on different subnet)
  • added SO_RCVTIMEO option in BSD socket interface to set blocking receive timeout
  • added support for AAAA-records in DNS client (resolves IPv6 address)
