+## v1.1.3

+Supports Intel SGX SDK v2.11, and Rust nightly-2020-10-25. Added support to Ubuntu 20.04. [release_notes](release_notes.md).

 ## v1.1.2
 
 Supports Intel SGX SDK v2.9.1, and Rust nightly-2020-04-07. v1.1.2 provides a handy crate `sgx_signal`, which enables signal capture. One can easily find the place where exception happens and finally triggered `ud2`. And we added `Backtrace::capture` in sgx_tstd. With the help of Intel SGX SDk v2.9.1's patch, dtor of thread local storage finally works on regular SGX thread and pthread thread. Removed sgx_core_futures since Rust is supporting `async`/`await` in `no_std` environment. Please refer to [release_notes](release_notes.md) for more details.
