Deployment management<\/h3>\n

Rolling release<\/h3>\n

A rolling release is where the software is released to users in phases, often following a geographical pattern. Android operating system updates usually operate on a rolling release schedule.<\/p>\n

Nightly Builds & Stable Build<\/h3>\n

Some modern software systems, especially open source systems, operate on a rapid application development(RAD) model where new features are constantly being added. When a user updates their system they can choose between the newest nightly build\u00a0\/developer build<\/strong>\u00a0version which has all the newest features but also likely more bugs, or a stable build<\/strong> with a slightly older feature set but fewer bugs.<\/p>\n\n<\/div>

Regular Updates<\/h2>\n

Regular Maintenance Updates<\/h3>\n

Most modern web-based systems require regular maintenance updates in order to keep the system running. The updates usually stick to a regular update cycle, such as once a week or once a month. These regular updates include:<\/p>\n

API update support<\/strong><\/p>\n

Most complex systems use online API calls in order to fetch data. If these APIs are updated or withdrawn then the system needs to be updated in order to keep functioning.<\/p>\n

Non-critical security updates<\/strong><\/p>\n

Many security issues often don’t pose an immediate threat and so need to be addressed in regular updates and or to keep ahead of the cat and game security game.<\/p>\n

Minor feature updates<\/strong><\/p>\n

This can include things such as support for additional languages or file types.<\/p>\n

 <\/p>\n\n<\/div>

Security Patches<\/h2>\n
\n\n

Security Patches<\/h3>\n

Often a critical security threat<\/strong> will emerge in the wild that necessitates an immediate system update. These vulnerabilities can leave the system open to a zero-day exploit<\/a> that could result in serious consequences.<\/p>\n

There should be a system in place that allows for security patches to be pushed to the target system immediately in order to address the threat.<\/p>\n\n<\/div>

Hard vs Soft<\/h2>\n

Hard vs Soft Releases<\/h3>\n

Hard Release<\/h3>\n

This is where software is to add users immediately and the availability is advertised or pushed to all available users immediately.<\/p>\n
