Comp.arch: /* History */ Move in order. Python 3.15 will "Make UTF-8 mode default" is likely a breaking change too, depending on what it means, or it wouldn't be opt-in. Just having it internally might not be breaking, so I do not move it to the new subsection. It will likely break C modules, though "removed wstr" already did that, and I think no further breakage needed. For I/O it will be a breaking change expecting input to be in UTF-8, also on Windows. But until see for sure what will happen in no move.

	Python 3.13 introduces more syntax for types; a new and improved interactive interpreter ([[read–eval–print loop\|REPL]]), featuring multi-line editing and color support; an incremental garbage collector, which results in shorter pauses for collection in programs that have many objects, as well as increasing the improved speed in 3.11 and 3.12); <!-- "A modified version of mimalloc is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode." --> an ''experimental'' [[just-in-time compilation\|just-in-time (JIT) compiler]] (such features, can/needs to be enabled specifically for the increase in speed);<ref>{{Cite web \|title=What's New In Python 3.13 \|url=https://docs.python.org/3.13/whatsnew/3.13.html#experimental-jit-compiler \|access-date=2024-04-30 \|website=Python documentation \|language=en}}</ref> and an ''experimental'' free-threaded build mode, which disables the [[global interpreter lock]] (GIL), allowing threads to run more concurrently, as enabled in<code>python3.13t</code> or <code>python3.13t.exe</code>.
