### Conan 1.43 Documentation Summary

#### 1. **Release Highlights**
- **Version Compatibility**: Conan 1.43 is designed to maintain backward compatibility with existing 1.0 recipes and command-line invocations. Any breaking changes are considered critical and should be reported.

- **Download Progress**: Enhanced human-readability of download progress and help messages.

#### 2. **Bug Fixes**
- **CMakeDeps Generator**: Fixed an issue where the `cmake_build_modules` property was not being properly used in components.
- **pkg_config Generator**: Made the generator listen to `cpp_info` properties from the root.
- **MSVC Compatibility**: Resolved issues with MSVC not working for CMake legacy generators.
- **Compiler Detection**: Improved compiler detection using built-in macro definitions instead of parsing compiler versions directly.

#### 3. **Deprecated Features**
- **Legacy Tools**: Deprecated `tools.msvc_build_command` and `tools.build_sln_command`.
- **Environment Variables**: Deprecated `CONAN_USERNAME` and `CONAN_CHANNEL`.

#### 4. **New Workflows**

- **Binary Creation**: Released `pyinstaller` code for creating Conan binaries from source, aiding package creation for distributions.

#### 5. **Community and Adoption**
- ** widespread adoption**: Used by hundreds of companies (e.g., Audi, Mercedes-Benz) and thousands of developers.
- **Contributions**: The Conan project (GitHub) has over 3.5K stars and nearly 200 contributors. The ConanCenter index has thousands of community-contributed packages.

#### 6. **Other Changes**
- **Package ID Management**: Fixed issues with duplicate package IDs and incorrect information during `package_id` method calls.
- **Improved SCM Detection**: Enhanced detection of version control systems (e.g., avoiding issues with `git` not being present).
