Python 2.6 was released to coincide with Python 3.0, and included some features from that release, as well as a "warnings" mode that highlighted the use of features that were removed in Python 3.0. [ 28 ] [ 10 ] Similarly, Python 2.7 coincided with and included features from Python 3.1, [ 29 ] which was released on June 26, 2009.
Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of Python 2. [37] Python consistently ranks as one of the most popular programming languages, and has gained widespread use in the machine learning community. [38] [39] [40] [41]
Since version 3.1, updates have been indicated by adding an extra digit at the end, so that the version number asymptotically approaches the number π, so 3.14 effectively means 3.2 in semantic versioning. (This is a form of unary numbering; the version number is the number of digits.) As of February 2021, the version number is 3.141592653 (3.9).

Ubuntu releases are also given code names, using an adjective and an animal with the same first letter – an alliteration, e.g., "Dapper Drake".With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer.
The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. . The kernel, device drivers, services, Security Accounts Manager, and user interfaces can all use the regis
Update all the copies on other caches (write-broadcasting), while the memory may be updated (write through) or not updated (write-back). Note: Coherency generally applies only to data (as operands) and not to instructions (see Self-Modifying Code). The schemes can be classified based on: Snoopy scheme vs Directory scheme and vs Shared caches
