### Conan 2.1 Documentation Summary

Conan 2.1 is an open-source, decentralized C/C++ package manager designed to work across platforms, build systems, and compilers. This version introduces several significant improvements and new features, particularly focused on enhancing functionality, usability, and compatibility.

#### Key Features and Improvements:

1. **New Commands and Verbosity Control**:
- Added `-v` and `--logger` options to control output verbosity and log in JSON format for processing.
- Restored the `conan config list` command for better configuration management.

2. **Enhanced Graph Model**:
- Introduced a new graph model to better support C/C++ binary relationships, compilation, and linkage.
- Defined requirement traits (e.g., headers, libs, build, run) and package types (e.g., static, shared, header-only) for improved dependency management.

3. **Public Python API**:
- Released a modular, documented Python API for advanced automation and customization.
- Provides sub-APIs for functional groups like `api.list`, `api.search`, and `api.graph`.

4. **Build System Integrations**:
- Enhanced build system integrations, including support for CMakeDeps and CMakeToolchain for transparent integration.
- Added new custom user commands that can be shared and installed via `conan config install`.

5. **Improved Lockfiles and Cache**:
- Introduced simpler and more powerful lockfiles for better reproducibility.
- Allowed multiple cache revisions to be stored simultaneously.

6. **Configuration and Environment Management**:
- Enhanced configuration with `[conf]` and improved environment management using `conan.tools.env`.

7. **Binary Compatibility and Deployment**:
- Added compatibility.py for global binary compatibility definitions.
- Introduced deployers mechanism to copy artifacts from the cache to user folders.

8. **Migration and Compatibility**:
- Ensured compatibility with Conan 1.X, allowing recipes and binaries to coexist in the same repositories.
- Provided a migration guide for users transitioning from Conan 1.X to 2.0.

9. **Experimental Features**:
- Added experimental features like `conan inspect`, which provides detailed information about Conanfiles.
