# What is new in version 0.7.1 ?

1. Full support for bit-fields
   Bit fields are now supported in the standard way.
2. New headers files
   A new header file is now provided for each pic18 device. These headers are compatible with Microchip's headers, but are not a copy of them.
3. New `inc2h-v2` utility
   This is a new version of the previous `inc2h` that is able to build the headers files from Microchip's «`.inc`» files.

4. Explicit bit-fields
   This feature is an extension of the standard that allows to slice any 8 bit variable in bit fields.

5. Support for the `const` keyword
   `const` is now supported as specified by the ANSI standard. Because the compiler is now more strict about constness, old codes may have to be slighly modified.
6. Minor bug fixes
