• FIX: Implicit capture of 'this' via '[=]' is deprecated in C++20.

• IMPROVEMENT: Code formatting.
• IMPROVEMENT: Refactored inner malloc flag processing.
• IMPROVEMENT: Made methods of InnerMallocFlag class protected.
• FIX: Removed unnesessary in-class initialization.
• IMPROVEMENT: Refactoring - templated flag.

Version 2.0.37

• IMPROVEMENT: Timer class made templated too.
• IMPROVEMENT: S- IMPlified condition in printReportTotal().
• IMPROVEMENT: Code style.
• FIX: Segfault when hangup logging interactive session.
• FIX: __cxa_guard_acquire deadlock on 5.x Linux kernels due to libC issue.

• IMPROVEMENT: The printReportTotal() function made reads the array under a row-level lock while writing to the file at runtime to ensure consistency.
• IMPROVEMENT: Some code formatting.
• IMPROVEMENT: Added function name in printReportTotal() not found message.
• FIX: Code formatting.

Version 2.0.36

• IMPROVEMENT: Best computeTotalLoggingTime() implementation.
• FIX: Comment for Now().

Version 2.0.35

• IMPROVEMENT: Used steady_clock instead system_clock in Now().
