This fork from [jcifs-ng](https://github.com/AgNO3/jcifs-ng) merges backward compatibility with legacy SMB devices while supporting modern SMB2/SMB3 protocols. Key features include SMB2 support, per-context configuration, SLF4J logging, NTLMSSP/Kerberos authentication, and streaming operations.

## Version

[Versions in Maven Repository](https://repo1.maven.org/maven2/org/codelibs/jcifs/)

## Requirements

- Java 17 or higher
- SLF4J for logging
