 * New Feature: `retdec-fileinfo` can be configured via JSON file. See `--fileinfo-config` option for more details.
 * New Feature: RetDec is now also a library ([#779](https://github.com/avast/retdec/pull/779). Related changes are the removal of `retdec-decompiler.py` (it is now a binary, e.g. `retdec-decompiler.exe` on Windows), `retdec-bin2llvmir`, `retdec-llvmir2hll`, and some other supportive functionality.
+* Enhancement: Provide one-line-style values for digital signature's subjects and issuers ([#956](https://github.com/avast/retdec/issues/956), [#976](https://github.com/avast/retdec/pull/976), [regression tests #92](https://github.com/avast/retdec-regression-tests/pull/92)).

 * Enhancement: Unified logging on stdout/stderr. Added option `--silent`. Printed text is colored only when output is a terminal ([#791](https://github.com/avast/retdec/issues/791).
 * Enhancement: Support all the CMake build types (i.e. `Debug`, `Release`, `RelWithDebInfo` and `MinSizeRel`) on all systems ([#774](https://github.com/avast/retdec/issues/774)).
