+### Feature: new session options — citations, agent exclusions, and credit limits
+
+Three new options are available on `SessionConfig` and `ResumeSessionConfig`. `enableCitations` (experimental) enables native model citations for supported providers; `excludedBuiltInAgents` hides named built-in agents from discovery; and `sessionLimits` sets a per-session AI-credit budget. ([#1865](https://github.com/github/copilot-sdk/pull/1865))
+
+```java
+SessionConfig config = new SessionConfig()
+    .setEnableCitations(true)
+    .setExcludedBuiltInAgents(List.of("copilot"))
+    .setSessionLimits(new SessionLimitsConfig(100.0));
+```
