Software update
Software update is the process of changing installed software with the intent to make it more modern. It also refers to the stored data used to update software. When storage was significantly more expensive, patching files was the dominant form of update. With the advent of larger distribution storage media and higher Internet bandwidth, it became common to replace entire files instead of patching.
An update may require prior application of other updates, or may require prior or concurrent updates to multiple components. To facilitate updates, operating systems often provide automatic or semi-automatic updating facilities. Package management systems offer update automation.
An update can be any size. An update can be relatively large when the changes add or replace data such as graphics and sound files; for example for a game update. An update usually takes less time to run than an initial installation of the software.
Although often intended to upgrade, an update may instead degrade. An update may include unintentional regression problems. In some cases, an update intentionally disables functionality, for instance, by removing aspects for which the consumer is no longer licensed.
Software update systems allow for updates to be managed by users and software developers. In the 2017 Petya cyberpandemic, the financial software "MeDoc"'s update system is said to have been compromised to spread malware via its updates. On the Tor Blog, cybersecurity expert Mike Perry states that deterministic, distributed builds are likely the only way to defend against malware that attacks the software development and build processes to infect millions of machines in a single, officially signed, instantaneous update. Update managers also allow for security updates to be applied quickly and widely. Update managers of Linux such as Synaptic allow users to update all software installed on their machine. Applications like Synaptic use cryptographic checksums to verify source/local files before they are applied to ensure fidelity against malware.
Automatic updating has become more widespread over time. Some cite a cause of its prevalence to be due to Windows support in early 2000s. Service Pack 2 of Windows XP (available in 2004) enabled it by default.
Updates are classified many ways. Notable classifications in alphabetical order follow.
A hotfix is a software update that is released outside the normal update cycle or intended to be applied to a live system; often to fix a bug.
