The following six Unicode standard annexes and technical standards were updated in version 15.0 (Unicode properties and specifications determine how text behaves on computers and mobile phones.):
- UAX #9, The Unicode Bidirectional Algorithm, modifies the comments in UAX9-C2 to emphasize the use of higher-level protocols to mitigate potential source code spoofing attacks.
- UAX #31, Unicode Identifiers and Pattern Syntax, provides more guidance for configuration files for default identifiers, clarifies the use of default-ignorable code points in identifiers, and discusses Pattern_White_Space and bidirectional ordering issues in programming languages relationship between.
- UAX #38, Unicode Han database, added kAlternateTotalStrokes property. Changed category of kCihaiT attribute to dictionary index, extended kKangXi attribute, and added sections 3.0, 3.10, and 4.5.
- UTS #39, Unicode Security Mechanisms, changed the zero-width joiner (ZWJ) and zero-width nonjoiner (ZWNJ) characters from Identifier_Status=Allowed to Identifier_Status=Restricted; therefore, the Universal Security Profile no longer allows them by default .

The Unicode standard is the foundation of all modern software and communications around the world, including operating systems, browsers, laptops and smartphones, as well as the Internet and the Web (URL, HTML, XML, CSS, JSON, etc.). The Unicode Standard, its related standards and data form the basis of the CLDR and ICU versions.
