v0.4: ### Notable changes

Notable changes

• Bundle the official lexicons for app.bsky and com.atproto, use them by default.
• Base:
  • Expose lexicons in defs attribute.
• Client:
  • Add minimal auth support with access_token and refresh_token constructor kwargs and session attribute. If you use a Client to call com.atproto.server.createSession or com.atproto.server.refreshSession, the returned tokens will be automatically stored and used in future requests.
  • Bug fix: handle trailing slash on server address, eg http://ser.ver/ vs http://ser.ver.
  • Default server address to official https://bsky.social PDS.
  • Add default User-Agent: lexrpc (https://lexrpc.readthedocs.io/) request header.
• Server:
  • Add new Redirect class. Handlers can raise this to indicate that the web server should serve an HTTP redirect. Whether this is official supported by the XRPC spec is still TBD.
• flask_server:
  • Return HTTP 405 error on HTTP requests to subscription (websocket) XRPCs.
  • Support the new Redirect exception.
  • Add the error field to the JSON response bodies for most error responses.
