• The dependency multicodec was updated from 0.2.7 to 0.4.0.

Update to this version instead 🚀

Release Notes for v0.4.0

• Revert "feat: make adding a custom codec possible" (9e251ce)

Chores

• fully automatic table generation (f3d8c0d)

BREAKING CHANGES

• multibase is not part of this package anymore

As multibase works differently from multicodec, those codecs
were removed from the multicodec table, hence those are also
removed from this implementation as we have automatic
conversion from the upstream table.

• the addCodec() function is removed

The addCodec() function is removed as it doesn't work as expected.
Things break as soon as the module is loaded several times, which
can happen if dependencies require a different version.

Steps to reproduce this problem:

$ mkdir addcodecbug
$ cd addcodecbug
$ npm install cids@0.5.7 multicodec@0.3.0
npm WARN saveError ENOENT: no such file or directory, open '/tmp/addcodecbug/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/tmp/addcodecbug/package.json'
npm WARN addcodecbug No description
npm WARN addcodecbug No repository field.
npm WARN addcodecbug No README data
npm WARN addcodecbug No license field.
+ multicodec@0.3.0
