 #### Added
  - CMake: Added `secp256k1_objs` interface library to allow parent projects to embed libsecp256k1 object files into their own static libraries.
  - build: Added `SECP256K1_NO_API_VISIBILITY_ATTRIBUTES` preprocessor flag (CMake option: `SECP256K1_ENABLE_API_VISIBILITY_ATTRIBUTES`) that disables explicit "visibility" attributes for API symbols. Defining this macro enables the user to control the visibility of the API symbols via `-fvisibility=<value>` when building libsecp256k1. (All non-API declarations will always have hidden visibility, even with `SECP256K1_ENABLE_API_VISIBILITY_ATTRIBUTES` defined.) For instance, `-fvisibility=hidden` can be useful even for the API symbols, e.g., when building a static libsecp256k1 which is linked into a shared library, and the latter should not re-export the libsecp256k1 API.
 
 #### Changed
- - The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` to the constant context object are now const.
+ - The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` to the constant context objects are now `const`.
  - Removed `SECP256K1_WARN_UNUSED_RESULT` attribute (defined as `__attribute__ ((__warn_unused_result__))`) from several API functions that always return 1. Compilers will no longer warn if the return value is unused.
  - CMake: Building with CMake is no longer considered experimental.
  - CMake: The minimum required CMake version was increased to 3.22.

 #### ABI Compatibility
 The symbols `secp256k1_ec_privkey_negate`, `secp256k1_ec_privkey_tweak_add`, and `secp256k1_ec_privkey_tweak_mul` were removed.
-The pointers `secp256k1_context_static` and `secp256k1_context_no_precomp` have been made const.

 Otherwise, the library maintains backward compatibility with version 0.6.0.

 The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6).
 Therefore, this version number does not uniquely identify a set of source files.
