0.9.1 - Trajectory Correction

Welcome to Nostrum 0.9.1, code-named "Trajectory Correction".

We're proud to announce the latest all-American release of Nostrum 0.9.1, a
bugfix bonanza built with the spirit of liberty in mind. Covering bugfixes to
new features to countless documentation improvements, upgrade today to harness
the power of the American dream in your Discord applications.

Breaking Changes

• Remove Nostrum.Api.get_token by @jchristgit in #569
  • As Nostrum moves to support multiple bots / library usage functionality like
    this is not desirable and as such as are removing features like this.
  • This field is set by the user anyway, so there are other methods to fetch
    this without depending on library functionality.
• Implement memory optimizations in user struct by @jchristgit in #567
  • Removes automatic parsing of the flags attribute of User structs, but
    the Nostrum.Struct.User.Flags struct still exists to allow users to
    optionally parse this value themselves.
  • This change saves considerable storage in cache as we are now able to store
    the flags as the integer we receive them as from Discord instead of in a
    custom struct with a large number of attributes.
  • This PR also removes the mfa_enabled, verified and email attributes
    that would only be set with OAuth2. We do not expect anyone writing regular
    bots to have any dependence on these properties.

Features

• Add missing fields from member API object by @jb3 in #573
  • Adds the pending, flags and avatar (custom guild avatar) attributes to
    Member struct
  • Also adds a helper method avatar_url/3 to the Member struct for fetching
    guild member custom avatars.
  • Adds a helper module Nostrum.Struct.Guild.Member.Flags for parsing flag
    values related to member onboarding.

Fixes

• Re-support uploading files from memory by @jb3 in #560
• Don't attempt to convert integers to atoms in map casting by @jb3 in #572
• Only attempt resume if the gateway says we can by @jchristgit in #566
• Drop session on invalid and unresumable session by @jchristgit in #580

    candidate to our test matrix in this PR to spot any potential teething
    issues with the upcoming release.
