v2.1.0

• Add "critical" severity level between "fatal" and "error".

v2.0.0

• Optimization: Avoid extra allocation when creating the LogMetaData. BREAKING CHANGE: members of LogMetaData (that is passed to users of custom sink) have different data types now:

-   std::string process_name;
-   std::string file;
-   std::string line;
-   std::string func;
-   std::string severity_name;
+   std::string_view process_name;
+   std::string_view file;
+   std::string_view line;
+   std::string_view func;
+   std::string_view severity_name;

Depending on how these were used, may require no modification in user code.

• Requirements: Bump minimum required C++ standard to C++17.
• Bugfix: Avoid semicolon insertion when modifying linker flags.
