0.14.0

[ssilverman]

Added

• Added a util::StdioPrint class, a Print decorator for stdio output files. It routes Print functions to a specific FILE*. This exists mainly to make it easy to use Printable objects without needing a prior call to fflush().
• Added MDNSClass::maxServices().
• Added operator==() and operator!=() operators for const IPAddress. They are in the usual namespace. These allow == to be used with const IPAddress values without having to use const_cast, and also introduce the completely missing != operator.
• Added a way to declare the _write() function as weak via a new QNETHERNET_WEAK_WRITE macro. Defining this macro will cause the function to be declared as weak.
• Implemented EthernetFrameClass::availableForWrite().
• Added size limiting to EthernetFrameClass write functions.
• New EthernetClass::waitForLink(timeout) function that waits for a link to be detected.
• Added a way to allow or disallow receiving frames addressed to specific MAC addresses: EthernetClass::setMACAddressAllowed(mac, flag)

Changed

• Updated SNTPClient example to use EthernetUDP::send() instead of beginPacket()/write()/endPacket().
• Updated PixelPusherServer example to use the frame average for the update period.
• Implemented EthernetHardwareStatus enum for the deprecated Ethernet.hardwareStatus() function. This replaces the zero return value with the new non-zero EthernetOtherHardware.
• Cleaned up how internal IP addresses are used.
• Changed _write() (stdio) to do nothing if the requested length is zero because that's what fwrite() is specified to do.
• Updated examples to use new operator!=() for IPAddress.
• Moved lwIP's heap to RAM2 (DMAMEM).
• Updated EthernetFrame-related documentation to explain that the API doesn't receive any known Ethernet frame types, including IPv4, ARP, and IPv6 (if enabled).
• Clarified in the examples that Ethernet.macAddress() retrieves, not sets.
• Changed EthernetClass::setMACAddress(mac) parameter to const.
• Moved CRC-32 lookup table to RAM2 (DMAMEM).
• Made const those functions which could be made const.
• Updated examples and README to consider listeners and their relationship with a static IP and link detection.

Fixed

• Fixed EthernetUDP::send() function to take the host and port as arguments, per its description. There's now two of them: one that takes an IPAddress and another that takes a char * hostname.
• Fixed enet_output_frame() to correctly return false if Ethernet is not initialized.
• Fixed not being able to set the DNS server IP before starting Ethernet.
• Fixed raw frame API to consider any padding bytes.
