• [changed] Breaking Change: The BlockThreshold enum in SafetySetting has been renamed to HarmBlockThreshold. (#13696)

• [changed] Breaking Change: The property citationSources of CitationMetadata has been renamed to citations. (#13702)

• [changed] The default request timeout is now 180 seconds instead of the platform-default value of 60 seconds for a URLRequest; this timeout may still be customized in RequestOptions. (#13722)
• [changed] The response from GenerativeModel.countTokens(...) now includes systemInstruction, tools and generationConfig in the totalTokens and totalBillableCharacters counts, where applicable. (#13813)
