Release Notes

ashtuchkin/iconv-lite (iconv-lite)

v0.6.3

Compare Source

• Fix HKSCS encoding to prefer Big5 codes if both Big5 and HKSCS codes are possible (#​264)

v0.6.2

Compare Source

• Support Uint8Array-s decoding without conversion to Buffers, plus fix an edge case.

v0.6.1

Compare Source

• Support Uint8Array-s directly when decoding (#​246, by @​gyzerok)
  • Unify package.json version ranges to be strictly semver-compatible (#​241)
  • Fix minor issue in UTF-32 decoder's endianness detection code.

v0.6.0

Compare Source

• Updated 'gb18030' encoding to :2005 edition (see https://github.com/whatwg/encoding/issues/22).
  • Removed iconv.extendNodeEncodings() mechanism. It was deprecated 5 years ago and didn't work
    in recent Node versions.
  • Reworked Streaming API behavior in browser environments to fix #​204. Streaming API will be
    excluded by default in browser packs, saving ~100Kb bundle size, unless enabled explicitly using
    iconv.enableStreamingAPI(require('stream')).
  • Updates to development environment & tests:
    • Added ./test/webpack private package to test complex new use cases that need custom environment.
      It's tested as a separate job in Travis CI.
    • Updated generation code for the new EUC-KR index file format from Encoding Standard.
    • Removed Buffer() constructor in tests (#​197 by @​gabrielschulhof).

v0.5.2

Compare Source

• Added iconv.getEncoder() and iconv.getDecoder() methods to typescript definitions (#​229).
  • Fixed semver version to 6.1.2 to support Node 8.x (by @​tanandara).
  • Capped iconv version to 2.x as 3.x has dropped support for older Node versions.
  • Switched from instanbul to c8 for code coverage.
