March 2026: Implemented Android-specific TLS stack hardening and certificate management for matrix-org/matrix-rust-sdk, including a custom rustls setup with JNI access to credential storage and post-rustls root-certificate support to improve secure connectivity. Replaced the platform verifier with a dedicated webpki verifier on Android to address false positives for revoked certificates, enhancing TLS reliability. Introduced Android SSL certificate management capabilities, including loading of custom certs and support for TLS verification toggling for testing and flexibility. Added the HomeserverCapabilities component to fetch, cache, and query capabilities (e.g., password changes, profile updates) to improve feature discovery and UX. Refactored HTTP client error handling to remove unwraps and added HttpError::VerifierBuilder for clearer error reporting on TLS verifier creation. Optimized Client::new to remove an unnecessary OAuth instantiation when using CrossProcessLockConfig::SingleProcess, reducing startup overhead and improving initialization performance.
