v3.0.0-alpha

• Did a large refactor of paths (release_path, current_path, document_root)
• Provide two recipes (base and advanced) and examples for both
• v2.0.0 did not work with symlink deployments, this now works again (see #8)
• Updated from Deployer 7.2 to 7.3
• New config options (see set.php):
  • wp/configFiles for wp-config/wp-config-local files which should be protected by more restrict file permissions
  • wp/configFiles/permissions for the chmod permissions to apply to the configFiles
  • Removed document_root - use release_or_current_path instead
• New/changed task names:
  • push_code now is called update_code again for parity with PHPDeployer.

Most of it stems from the issues surfaced in #8
