The soul of this release is the full refactoring and updating of the "Code Conventions" chapter:

• All code conventions have been reviewed again, adding missing items and improving the organization of the existing ones
• "Core C+"+ code convention has been fully added
• Mentioned code convention tools likeclang-tidy
• All bullet points now have links to the official convention descriptions
• The chapter has been split into two lectures and organized into several subsections to improve the readability

Introduction:

• Updated main charts: "C++ popularity" and "compute-trend"
