# APBS 0.1.5 (2001-10)

This version features minor bug fixes and several new features:

- Fixed shift in center of geometry for OpenDX I/O
- Made energy evaluation more robust when using NPBE
- Rearrangments of files and modified compilation behavior
- Input file support for ion species of varying valency and concentration
- Input file support incorrect nlev/dime combinations; APBS now finds acceptable settings near to the user’s requested values
- “Automatic focusing”. Users now simply specify the physical parameters (temperature, dielectric, etc.), the coarse and fine grid lengths and centers, and APBS calculates the rest
