It provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference by the application of work to the system. The Carnot cycle is a theoretical ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s.

Major new features of the 3.10 series, compared to 3.9Īmong the new major new features and changes so far: Although in most cases this was not very noticeable, it was very impactful for long-running applications and certain usage patterns. The memory leak consisted of a small constant amount of bytes in certain function calls from Cython code.

This is a special bugfix release ahead of schedule to address a memory leak that was happening on certain function calls when using Cython. Python 3.10.2 is the newest major release of the Python programming language, and it contains many new features and optimizations. This is the second maintenance release of Python 3.10
