-## pe2sgxs
+## pe2sgxs (deprecated since v0.8.7)
 
 `pe2sgxs` converts enclaves in Intel's PE format to SGXS format, optionally
 extracting the signature. You can then use the SGXS file with the other SGXS
 utilities.
 
+This is deprecated since v0.8.7 because the code of its dependency `pe` is
+incompatible with rust compiler since `nightly-2023-01-31`. The source code has
+been moved to `src/deprecated`.
+
 ## sgx-debug-read
 
 `sgx-debug-read` tries to read memory in the EPC. This will only succeed for

intel-sgx/sgxs-tools/src/bin/isgx-pe2sgx.rs → intel-sgx/sgxs-tools/src/deprecated/isgx-pe2sgx.rs
