- NEW: The heap allocator has been modified, now it is possible to have
multiple heaps. The default heap gets its memory from the new core memory
manager.
-- NEW: Added a "hungry" mode to the memory pools allocator, when enabled, this
- mode makes a memory pool to feed memory from the core memory manager.
+- NEW: Now memory pools can optionally get new objects automatically from the
+ core memory manager.
- NEW: Added newlib interface file syscalls.c under ./os/various for use with
the newest YAGARTO releases. The file provides bindings between the C
runtime and the core memory manager.
