0.5

• Added support for decompilation of files in archives (ar format). Archives
  are statically linked libraries, commonly ending with .a or .lib. To
  decompile a file from an archive, use the bin mode and pass either the
  index of the file in the archive (ar_index) or its name (ar_name). New
  since RetDec 2.2.
• Added a new optional parameter output_format to the fileinfo service.
  You can use it to obtain the output in the JSON format. New since RetDec 2.2.
• Added support for decompilation of files in the Intel HEX format. To
  decompile such files, use the bin mode and pass the architecture and
  endianness of the machine code inside the file. New since RetDec 2.2.
• The raw_entry_point and raw_section_vma parameters in raw
  decompilations no longer accept the default value. In both cases, you
  have to explicitly pass an address. New since RetDec 2.2.
• The raw_endian parameter was renamed to endian. Use of the original
  name is still supported, but it is deprecated. New since RetDec 2.2.
• It is no longer possible to force an architecture when decompiling a file in
  the bin mode. The architecture is now detected automatically from the
  input file. New since RetDec 2.2.
• It is no longer required to set file_format in raw decompilations. When
  given, it will be ignored. New since RetDec 2.2.
• Compiler-optimization levels can now be also specified without the leading
  dash (e.g. you can pass O1 instead of -O1). New since RetDec 2.2.
• Dropped support for Python 3.2 (the requests module, which is used for
  HTTPS communication, no longer supports it).
