A preview build is an early version of software released to a limited group of users or testers before the final version is made available to the general public. These builds are intended for testing new features, identifying bugs, and gathering feedback to improve the software’s stability and security. In cybersecurity, preview builds may expose vulnerabilities or incomplete security features, making them riskier to use in production environments. Organizations and individuals using preview builds should be cautious, as these versions may not have undergone full security testing and could be more susceptible to cyber threats.
