Värskendus

Värskendus is the Estonian term for update or refresh. In information technology and digital systems, it refers to a change applied to software, firmware, or data to improve functionality, fix issues, patch security vulnerabilities, or incorporate new features.

Software updates are released by developers and can be delivered automatically or manually. They are distributed through operating system update mechanisms, app stores, or software repositories. Firmware updates are similar but target the embedded software that controls hardware devices such as routers, cameras, and printers.

Data or content updates refresh information sets to reflect the latest available content. This is common for maps, databases, caches, and news feeds, where keeping information current is essential for accuracy.

The update process typically includes planning, testing, deployment, and, if necessary, rollback. Updates may be incremental or major; developers release release notes describing changes, compatibility considerations, and potential impacts on performance.

Considerations for värskendus include versioning, compatibility with existing software and hardware, size and bandwidth requirements, user consent or automation settings, and the risk of introducing new issues. Proper backups and a clear rollback plan help mitigate disruption when updates fail.
