Updated versions of My Calendar are shipped fairly regularly. Minor updates are any change in the 3rd digit (e.g. updating from 3.5.6 to 3.5.7). In a minor update, very little will change; almost always only bug fixes. This doesn’t mean that nothing can go wrong, but generally the changes are slight.<\/p>\n\n\n\n
Major updates contain more significant changes. These changes may impact the front-end of your site.<\/p>\n\n\n\n
There is no significant difference between a second digit change (3.4 to 3.5) and a first digit change (3.9 to 4.0). <\/p>\n\n\n\n
My Calendar has upgrade processes that run whenever you do an update that requires significant changes. These updates may migrate options to a different format, add default values for new options, or modify the database.<\/p>\n\n\n\n
Upgrade paths are not maintained indefinitely. Any given upgrade path will be kept in place for approximately five years. <\/p>\n\n\n\n
Right now (August 30th, 2025), the oldest version with a full upgrade path is version 3.1.13, released in August 2019. This will be removed when version 3.7 is released.<\/p>\n\n\n\n
Since version 3.5, My Calendar is developed with an accessibility-first mindset. This means that if I need to make a breaking change for accessibility reasons, I will do this. Breaking changes will still only occur in major releases, and will never occur in a 3rd-digit release. <\/p>\n\n\n\n
Most accessibility changes will be modifications to the My Calendar HTML output, and the primary change that will occur on your site is that custom styles may break. <\/p>\n\n\n\n
Most likely, this is a caching issue. While something could go wrong in an update, the most common problem is that you have updated HTML or settings, but out of date CSS or JavaScript. <\/p>\n\n\n\n
If you have any caching plugins in your environment, clear those caches, then go and view your site in a private tab in your browser. This helps ensure that you’re not seeing it with either a cache from the site or a cache from your browser.<\/p>\n","protected":false},"excerpt":{"rendered":"
