Version 1.4.0

1.4.0

• segyio has learned how to resample a file (segyio.tools.resample). This
  function does not actually touch the data traces, but rewrites the header
  fields and attributes required to persistently change sample rate.
  Interpolation of data traces must be done manually, but for a strict
  reinterpretation this function is sufficient
• segyio has learned to read enough structure from a file to create a new file
  with the same dimensions and lines (segyio.tools.metadata)
• segyio has learned to create unstructured files (only traces, no inlines or
  crosslines)
• f.text[0] = requires bytes convertability. This catches some errors that
  were previously fatal or silent
• f.text broken internal buffer allocations fixed
• f.text[n] = supports strings longer or shorter than 3200 bytes by
  truncating or padding, respectively
• Fixed a bug where a particular length of mode strings caused errors
• segyio.open('w') raises an exception, instead of silently truncating the
  file and failing later when the file size does not match the expected.
• segy_traces now fails if trace0 is outside domain, instead of silently
  returning garbage
• Return correct size for dirty, newly-created files. This means carefully
  created new files can be mmapd earlier
• Methods on closed files always raise exceptions
• mmap support improved - all C functions are mmap aware.
• The file is now closed after a successful mmap call
• str.format used for string interpolation over the % operator
• Several potential issues found by static analysis, such as non-initialised
  temporaries, divide-by-zero code paths, and leak-errors (in process teardown)
  addressed, to reduce noise and improve safety
• Error message on failure in segyio.tools.dt improved
• Error message on unparsable global binary header improved
  changes for the next major release
• Catch2 is introduced to test the core C library, replacing the old
  test/segy.c family of tests
• Contract for segy_traces clarified in documentation
• Docstrings improved for depth_slice and segyio.create
• A new document, breaking-changes.md, lists planned deprecations and API
• The readme has gotten a makeover, with better structure, an index, and more
  examples
• setup.py requires setuptools >= 28. A rather recent setuptools was always a
  requirement, but not codified
• scan-build (clang analysis) enabled on Travis
