What's Changed

Added

• OAuth PKCE support - OAuthOptionCodeVerifier option for GetOAuthV2Response, plus GenerateCodeVerifier() and GenerateCodeChallenge() helpers (RFC 7636). client_secret is now conditionally omitted when empty in both GetOAuthV2ResponseContext and RefreshOAuthV2TokenContext.
• Manifest scope fields - BotOptional and UserOptional on OAuthScopes.
• Rich text styles - Underline, Highlight, ClientHighlight, and Unlink on RichTextSectionTextStyle. Style field on RichTextSectionUserGroupElement.
• Assistant search context - Sort, SortDir, Before, After, Highlight, IncludeContextMessages, IncludeDeletedUsers, IncludeMessageBlocks, IncludeArchivedChannels, DisableSemanticSearch, Modifiers, TermClauses parameters and new response types (AssistantSearchContextFile, AssistantSearchContextChannel, AssistantSearchContextMessageContext).

Fixed

• socketmode: malformed JSON no longer forces reconnect - json.SyntaxError and json.UnmarshalTypeError now emit an EventTypeIncomingError event and continue reading instead of killing the WebSocket connection.
• socketmode: debug_reconnects query param applied correctly - the parameter was silently discarded due to a missing url.RawQuery assignment.
• ChannelTypes and ContentTypes now send comma-separated values instead of repeated form keys, matching the convention used by every other method in the library.

Docs

• assistant:write scope marked as deprecated in favour of chat:write.
