v0.7

Notable changes

• Fix websocket subscription server hang with blocking server XRPC methods due to exhausting worker thread pool (#8).
• Add truncate kwarg to Client and Server constructors to automatically truncate (ellipsize) string values that are longer than their maxGraphemes or maxLength in their lexicon. Defaults to False.
• Add new base.XrpcError exception type for named errors in method definitions.
• flask_server:
  • Handle base.XrpcError, convert to JSON error response with error and message fields.
• Client:
  • Bug fix for calls with binary inputs that refresh the access token. Calls with binary input now buffer the entire input in memory. (snarfed/bridgy#1670)
  • Bug fix: omit null (None) parameters instead of passing them with string value None.
• Update bundled app.bsky and com.atproto lexicons, as of bluesky-social/atproto@15cc6ff37c326d5c186385037c4bfe8b60ea41b1.
