###
1.2 Tftp 1.0.4

####
Improvements and New Features

- Replace size/1 with either tuple_size/1 or byte_size/1

  The size/1 BIF is not optimized by the JIT, and its use can result in worse types for Dialyzer.

  When one knows that the value being tested must be a tuple, tuple_size/1 should always be preferred.

  When one knows that the value being tested must be a binary, byte_size/1 should be preferred. However, byte_size/1 also accepts a bitstring (rounding up size to a whole number of bytes), so one must make sure that the call to byte_size/ is preceded by a call to is_binary/1 to ensure that bitstrings are rejected. Note that the compiler removes redundant calls to is_binary/1, so if one is not sure whether previous code had made sure that the argument is a binary, it does not harm to add an is_binary/1 test immediately before the call to byte_size/1.
