icalendar 7.2.1 and 7.2.2 released.

7.2.1 is a security fix of GHSA-qjcq-q7h7-r74v: https://github.com/collective/icalendar/security/advisories/GHSA-qjcq-q7h7-r74v a crafted REPEAT on a VALARM could exhaust memory or CPU via Alarm.triggers and Alarms.

7.2.2 fixed the documentation build to fail.

#Images

I’ve always wanted to put images into my calendar appointments, and I just had the patience to figure out how.

Save the image as a file, and then attach the image file as an attachment in the appointment.

The image doesn’t show until you click it.

#icalendar

New blog post about calendars and calendar feeds. RSS is back, let's bring back iCalendar too!

https://shadenexus.ca/blog/posts/2026-05-19-calendar.html

#Web #Calendar #iCalendar #FOSS

It's so sad. With 📆 CalDAV we have a really nice open protocol for syncing events, todos and notes. The protocol, which is technically more of a file format (iCalendar) even supports quite complex reccurence rules and even things like recurring tasks.

Unfortunately, client (and server) applications usually only implement a subset of what's possible.

Know some good ones? Let me know!

#CalDAV #iCalendar #ics #Calendar #PIM #LinuxApps

Soo I extended my #hugo theme component for #icalendar #calendar entries a little… https://github.com/Finkregh/hugo-theme-component-ical#demo--resources

We have updated our #AI policy to disclose the collaboration between developers and AI agents.

https://pycal.org/ai-policy/

We aim to protect maintainers and projects while also providing clarity on what is expected.

Thanks to @PeskyPotato, #icalendar now has its first #tutorial!

🎉

Learn about how to create a #calendar #event, invite attendees and save it in an #ics file here:

What you recommend about fetching ICS calendar from website? To show events in some way. I'm thinking about general calendar, nextcloud, google, doesn't matter. Thanks!
#ics #icalendar #javascript #caldav #calendar

@PeskyPotato Right now, #icalendar only has https://icalendar.readthedocs.io/en/stable/how-to/index.html with lots of how-to guides. Devs can use a tutorial and we do not have any. We follow https://diataxis.fr for good documentation. That makes a clear distiction. I think you can either open a PR and get feedbak or open an issue.

@PeskyPotato Hi, i found your #icalendar tutorial:

https://blog.pesky.moe/posts/2025-01-02-create-icalendar/

We just released icalendar version 7 that makes it easier and uses properties and new() and I wonder: Would you like to add a tutorial like that into our official documentation?

Thanks!

#PythonIcalendar

A major #update to #icalendar for #Python has been released!

Read about new features, ease of use and improved #compatibility in our announcement: https://github.com/collective/icalendar/discussions/1229

We thank @nlnet for their #funding to make so much work possible!

#PythonIcalendar #rfc5545 #rfc7265

I am looking for a script to merge two ics files.

Given two ics files I need a new one that contains a semantically 'Ok' merge.

e.g. I don't care about fields like PRODID, just choose one.
Did it ACKNOWLEDGED changed? -> Use the data from the newer one ... and so on.

It gladly may ask user feedback if it is not trivial to merge.

#ics #ical #icalendar

I think I've fixed the bug where query string params weren't being used for @wm_au's event URLs, so it's now possible to do things like `https://wikimedia.org.au/events.ics?where=_pageID=4230` (and probably other silly things that break something else, I don't know).

#MediaWiki #iCalendar #WPBeans

To celebrate the new year, I, too, have decided to partake in the traditional GNOME bugfixing technique of… deleting code to make things work :blobmiou: (it turns out that some parts of calendaring standards specifications are pretty weird, and most other apps couldn't even render the alarm types we created)
