Can you explain the concept of trunk-based development in version control systems?

Trunk-based development is an approach to working with version control systems where all developers integrate their changes directly into the main branch (usually called trunk, main, or master) very frequently, sometimes multiple times a day.

Main ideas:

• Absence of long-lived feature branches — changes are quickly merged into the main branch.
• Frequent commits and integrations help quickly identify conflicts and errors.
• Use of feature flags or other mechanisms to control the visibility of new features.

Advantages:

• Minimizes merge conflicts.
• Provides rapid feedback.
• Simplifies the release process.

Example: a developer makes small changes, tests them locally, and immediately pushes to trunk. If a feature is not yet ready for use, it can be hidden behind a feature flag so as not to affect users.

Thus, trunk-based development promotes a more stable and predictable development process.
