Added

• IgnoreFilesystemAdapter filtering entries based on .gitignore-style ignore files (cascade, negation, **, directory-only), with a $strict mode and support for multiple ignore filenames
• RetryAdapter now supports a $multiplier argument enabling exponential backoff between attempts
• Suggest psr/log dependency, required to use the LogAdapter

Fixed

• FallbackAdapter no longer throws null and returns the last result (even false) when every adapter answered, instead of re-throwing an exception raised by the last adapter
• RetryAdapter now validates its retry (>= 1) and time (>= 0) constructor arguments and no longer sleeps after the last attempt
• ReadWriteAdapter now requires at least one reader and one writer adapter, preventing a null exception when a list is empty
• LogAdapter removed unreachable dead code in the log level resolution

Fixed

• FallbackAdapter::fileExists() and FallbackAdapter::directoryExists() now try next adapter in cas of FALSE result
