Release Notes

ashtuchkin/iconv-lite

v0.5.1

Compare Source

• Added cp720 encoding (#​221, by @​kr-deps)
  • (minor) Changed Changelog.md formatting to use h2.

v0.5.0

Compare Source

• Added UTF-32 encoding, both little-endian and big-endian variants (UTF-32LE, UTF32-BE). If endianness
  is not provided for decoding, it's deduced automatically from the stream using a heuristic similar to
  what we use in UTF-16. (great work in #​216 by @​kshetline)
  • Several minor updates to README (#​217 by @​oldj, plus some more)
  • Added Node versions 10 and 12 to Travis test harness.
