| | 7 | == Special Notes for this Release == |
| | 8 | |
| | 9 | * This release represents the first step in the planned switch to the more agile bi-annual release cycle. HelenOS is still an experimental operating system at this point in time and support for many platforms and hardware devices is not production-ready. For the time being, the agile bi-annual release cycle might therefore produce releases that are slightly less "polished" in certain aspects, but it is also a driving force towards turning HelenOS into a production-ready operating system in the near future. |

| | 44 | |
| | 45 | === Libraries === |
| | 46 | * libmath expanded to cover all C89 math functions (only generic/non-optimized implementation), including single-precision variants from C99 |
| | 47 | * Optimizations of the heap memory allocator |
| | 48 | |
| | 49 | === Miscellaneous === |
| | 50 | * XCW (Cross Compiler Wrapper) tools |
| | 51 | * Can be used by out-of-tree application to cross-compile for HelenOS |

| | 53 | * The application's build system is aware it is cross-compiling for HelenOS |
| | 54 | |
