@@ -12,6 +12,17 @@ What's New in Python 2.4 alpha 1? Core and builtins ----------------- +- Optimized list resize operations to make fewer calls to the system + realloc(). Significantly speeds up list appends, list pops, + list comprehensions, and the list contructor (when the input iterable + length is not known). + +- Changed the internal list over-allocation scheme. For larger lists, + overallocation ranged between 3% and 25%. Now, it is a constant 12%. + For smaller lists (n<=5), overallocation was upto eight bytes. Now, + the overallocation is no more than one byte -- this improves space + utilization for applications that have large numbers of small lists. + - Support for arbitrary objects supporting the read-only buffer interface as the co_code field of code objects (something that was only possible to create from C code) has been removed. |
