Migrating to v0.5.8

Tencent Hunyuan Native API v3

In v0.5.8, the Tencent provider was updated to use the native Tencent Cloud API v3 with TC3-HMAC-SHA256 signature.

Breaking Change:

• Old: LlmClient::tencent("api-key") (OpenAI compatible wrapper)
• New: LlmClient::tencent("secret-id", "secret-key") (Native API)

Migration:

// Before
let client = LlmClient::tencent("sk-...")?;

// After
let client = LlmClient::tencent("AKID...", "SecretKey...")?;

Migrating to v0.5.0

Multi-Modal Content

v0.5.0 introduced native multi-modal support, changing the Message.content field.

Breaking Change:

• Message.content is now Vec<MessageBlock> internally, though strictly speaking the public API might abstract this, direct field access may break.
• Helper methods like Message::text() should be used.

Migration:

// Before
let msg = Message { role: Role::User, content: "hello".to_string(), .. };

// After
let msg = Message::text(Role::User, "hello");
