Updating Software
The Koha software is always changing, almost every day. These changes contain
bug fixes, minor revisions to existing features, and entirely new features. You should
keep the software updated to benefit from these changes.
Even if the new versions do not contain changes of interest to you, it is good practice
to keep the software updated. If your version falls too far behind the current version,
the update process to the latest version is likely to be very difficult.
In this chapter we learn how to download and install software updates. We cover
the chapter in two steps - an orientation followed by a demonstration of the process.
