If you are still on PHP 5.3.3, you are strongly urged to update your PHP version to at least 5.4 as soon as possible. For those remaining on PHP 5.3.3 after the next release, although it is likely that future releases will still work, we can no longer guarantee that breaking changes will not be introduced. For those who are brave and do run into this issue down the road, we have tagged most modules in the Islandora Github organization with a php5.3-eol tag, denoting the last point in time when PHP 5.3.3 compatibility was known. These tags do not represent a release, and have not been fully tested by the community. So _there are no guarantees_, but they are a courtesy we’re extending for those stuck on PHP 5.3.3 who want to update to something recent.
There are a few repositories that did not get a php5.3-eol tag due to the fact that they do not contain code or are forks of other people's code we minimally maintain. For the record, the following repositories do not have a php5.3-eol tag:
We would like to thank everyone for their patience in this matter. We know it is hard to watch PRs languish due to our workflow, and we feel we've come up with a reasonable solution to unlock contributions while also giving opportunities for those still on PHP 5.3.3 to act. Please feel free to respond to this thread if you have any questions about the impact of this decision and what it might mean to you or your organization.
