PEP 741 : An improved C API for configuring Python. A new type of interpreter . For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source. Improved error messages. Builtin implementation of HMAC with formally verified code from the HACL* project. A new command-line interface to inspect running Python processes using asynchronous tasks. The pdb module now supports remote attaching to a running Python process . For more details on the changes to Python 3.14, see What’s new in Python 3.14 . PEP 761 : Python 3.14 and onwards no longer provides PGP signatures for release artifacts.

As we all recall from 3.14.0a1 , piphilology is the creation of mnemonics to help memorise the digits of π , and the number of letters in each word in a pi-poem (or "piem") successively correspond to the digits of π . In 1995, Mike Keith, an American mathematician and author of constrained writing, retold Poe's The Raven as a 740-word piem. Here's the first two stanzas of Near A Raven : Midnights so dreary, tired and weary. Silently pondering volumes extolling all by-now obsolete lore. During my rather long nap - the weirdest tap! An ominous vibrating sound disturbing my chamber's antedoor. "This", I whispered quietly, "I ignore". Perfectly, the intellect remembers: the ghostly fires, a glittering ember. Inflamed by lightning's outbursts, windows cast penumbras upon this floor. Sorrowful, as one mistreated, unhappy thoughts I heeded: That inimitable lesson in elegance - Lenore - Is delighting, exciting...nevermore. Midnights so dreary, tired and weary.
