Changelog

A set of upgrades focused on closing the loop with attendees wherever they read your events, plus sharper tools for managing recurring events and busy event lists.

Key New Features

• RSVP Links in Subscribed Calendar Feeds: Subscribers in Google Calendar, Apple Calendar, and Outlook now see a direct RSVP link at the top of every RSVP-enabled event description, so they can respond without switching back to the web.
• Localized RSVP Confirmation & Reminder Emails: Confirmation and reminder emails are now sent in the language the attendee saw on your public event page, across all 22 supported languages.
• Single-Occurrence Add to Calendar: For recurring events, you can now generate an add-to-calendar link, button, or embed that adds only the next single occurrence instead of the entire series.
• Smarter Event List Filters: Filter the events dashboard by tag, by RSVP-enabled only, or hide events imported from external calendars.
• Mobile Auto-Switch for Embedded Calendars: Embedded calendars can automatically switch to the schedule view on small screens for a cleaner mobile layout.

Improvements

• Better Recurring Event Editor: Sensible 10-occurrence default, an explicit choice between "ends after N occurrences" and "ends on a date," a complete preview when the rule is bounded, and a warning if the start date is in the past.
• Background Spam Protection: Automatic spam detection for events and calendars keeps public pages clean with no action needed from legitimate organizers.
• Account Security Hardening: Account deletion now requires password confirmation, magic login links are strictly single-use, external calendar imports are protected against SSRF, and we've added payload size limits.

Bug Fixes

We've also shipped a steady stream of fixes across external calendar sync, recurring series handling, the Google Calendar subscribe flow on Android, embed loading, billing edge cases, and plenty of smaller papercuts throughout the app.

We’ve rolled out a new set of platform upgrades and functional improvements to provide automated reporting for event organizers and cleaner customization options for public pages.

Key New Features:

• Final RSVP Summaries: Event owners now receive a one-time automated email once an event ends. This report includes final attendee counts (Yes, Maybe, No) and a link to the full list, providing closure on your event data without manual checks.
• Phone Number Form Fields: You can now add a dedicated Phone Number field to custom RSVP and subscription forms, featuring built-in validation and optimized UI for accurate contact collection.
• Advanced Analytics Integrations: Track performance with native support for Google Analytics, Fathom, Plausible, PostHog, Matomo, Umami, Simple Analytics, and Pirsch. Just add your ID in the settings to start measuring engagement.
• Webhooks & Zapier (Business Plan): Connect AddCal to your tech stack with real-time HTTP notifications for new RSVPs and subscriptions. Use our native Zapier integration or custom webhooks to automate workflows in your own applications.
• Hide Upcoming Events List: A new setting in Appearance Templates allows you to hide the "Upcoming Events" list on public calendar pages, perfect for keeping the focus on your main calendar view.

Our website calendar embed has been completely rebuilt to provide a premium, seamless experience for your visitors.

What’s New:

• Responsive Layouts: New Month, Week, and Schedule views that automatically adapt to mobile, tablet, and desktop screens.
• Deep Customization: Full control over themes (Light/Dark), custom Google Fonts, and 15+ color palettes to match your brand perfectly.
• Powerful Interactions: Includes live tag filtering, a searchable global timezone selector, and polished event overlays.

We’ve rolled out a new set of platform upgrades and functional improvements to give you better visibility into your schedule and more granular control over your event configurations.

Key New Features:

• New Calendar View Modes: You can now toggle between Month, Week, and Day views within the calendar. Your preferred view is automatically saved, so your dashboard always opens exactly how you like it.
• Microsoft Sign-In: We’ve expanded our authentication options. You can now securely sign up or log in to AddCal using your Microsoft account for a faster setup experience.
• Embedded Localization: You can now generate "Add to Calendar" embed codes and links in specific languages, ensuring the buttons and dropdowns match your website's local language.
• Duplicate RSVP Prevention: Organizers can now enable a setting to prevent multiple RSVPs from the same person. If an attendee submits a new response with the same email, their existing entry is updated rather than creating a duplicate.
• Hide Series Subscription Options: New template settings allow you to hide the "add entire series" or "future events" options for recurring events, giving you more control over how users subscribe to your series.
• Hide Event Location: We've added a new toggle to Appearance templates that allows you to hide the event location link if you prefer a cleaner event page layout.

This update introduces a programmatic way to generate event links, improved tools for managing large volumes of events, and additional branding controls.

Key New Features:

• Dynamic Links: Generate personalized add-to-calendar links programmatically from URL query parameters (similar to Addevent). A dedicated UI builder is now available in the dashboard to help construct these links instantly.
  • AddEvent Compatibility: We've also added a compatible "dynamic add-to-calendar" endpoint (/api/dyn_ade). This allows existing AddEvent integrations to be pointed at AddCal with minimal changes, featuring automatic parameter mapping and click tracking.
• Bulk Event Operations: Manage schedules more efficiently with new bulk actions in the event list. You can now select multiple events to delete, tag, or move them to a different calendar in a single operation.
• Shareable RSVP Lists: Securely share attendee data with collaborators. Organizers can generate a unique, read-only URL that allows stakeholders to view the RSVP list in real-time without needing an AddCal account or dashboard access.
• Custom Favicons: Upload a custom browser tab icon for both Event Templates and Custom Domains to ensure a fully white-labeled experience.
• Smarter RSVP Summaries: Daily notifications are now automatically throttled to a weekly cadence when no new responses are received to reduce email volume.

We’re kicking off February with powerful optimizations to help you manage event series and create more engaging pages.

New Features:

• Extended Rich Text (WYSIWYG) Editor: We’ve upgraded the editor for Calendars and Events. You can now add tables, inline pictures, and code blocks to make your descriptions stand out.
• Smart Event Series Inheritance: Editing a parent event now automatically updates all child events in the series—including links, images, and descriptions—saving you time on bulk updates.
• Massive Language Expansion: Our translation engine now supports the top 20 most-spoken languages globally, ensuring your content is accessible to a worldwide audience.
• Smart Subscription Alerts: To improve the user experience, we now alert users if they have already subscribed to a calendar. Instead of creating a duplicate entry, we simply reuse the existing subscription, keeping your data clean.

Other Improvements:

• Image Cropping Fixes: Resolved issues with calendar and event image cropping for a sharper look.
• Performance Tweaks: Backend optimizations to keep your dashboard fast, regardless of your event volume.

We’re happy to announce that all public calendar and event pages can now be translated into multiple languages, making your events more accessible to a global audience.

We are launching with support for French 🇫🇷, Spanish 🇪🇸, Hungarian 🇭🇺 and Hebrew 🇮🇱

🚀 Update: Language Expansion!

We've just added support for a huge range of new locales. You can now set your public pages to:

German 🇩🇪, Czech 🇨🇿, Portuguese 🇵🇹, Italian 🇮🇹, Dutch 🇳🇱, Polish 🇵🇱, Japanese 🇯🇵, Korean 🇰🇷, Turkish 🇹🇷, Russian 🇷🇺, Swedish 🇸🇪, and Arabic 🇦🇪.

How it Works

Your public-facing content—including event details, calendar views, and RSVP forms—will now adapt to your users' needs. We are also hard at work bringing these translations to our embedded calendars and buttons very soon!

Want to see your language added?

We want to support as many communities as possible. If there is a specific language you need for your audience, please reach out to us via live chat, and we will prioritize getting it added to the platform

We’re kicking off the year with a major new way to display your events, alongside some great performance and integration updates.

Event Page Embedding

You can now bring the full AddCal experience directly into your own website! With our new Event Page Embedding, you can embed both the event details and the RSVP form as a seamless part of your site. A premium subscription is required for this feature.

• Smart Resizing: The embed script automatically handles height adjustments to ensure your content always fits perfectly without awkward scrollbars.
• Keep Your Traffic: Keep visitors on your domain while providing the full functionality of an AddCal event page.
• Easy Setup: Just grab the smart snippet and drop it into your CMS or custom HTML.

Other Improvements

• Teams Meeting Buttons: Just like our Zoom integration, Microsoft Teams meeting links now automatically generate a prominent "Join Meeting" button on your event pages for a more professional look.
• Management Performance: We've optimized the backend for the event and calendar management pages. If you’re a power user with hundreds (or thousands!) of events, you’ll notice significantly faster load times and smoother navigation.
• Under-the-Hood Fixes: We've squashed several minor bugs to start the year with a clean slate.

We've rolled out a set of updates focused on improving the initial experience for new users and enhancing our integration capabilities.

• New Onboarding Flow: We've designed a brand new onboarding experience to help new users quickly set up their first calendar and event, guiding them to key features for a faster start.
• Custom 'Reply To' Email (Under Templates): You can now set a specific 'Reply To' email address within your Templates (Email Settings). This ensures that any replies to your RSVP confirmation and reminder emails go directly to the organizer's preferred inbox, streamlining communication.
• API Improvements: We've expanded our API capabilities with new RSVP management endpoints, allowing for programmatic control over attendees. We've also undertaken a major documentation cleanup to make integration smoother and faster than ever.

We've been cooking up some behind-the-scenes magic to make managing your events even smoother! This release focuses on giving you cleaner links, more control over your custom domain, and a better subscriber experience.

Key New Features:

• Custom Short Links for Calendars: We've extended our short link functionality so that Calendars (in addition to events) can now utilize custom short links.
• Clean URL Format on Custom Domains: This enhancement allows both calendar and event links on your custom domain to use clean, memorable URLs (e.g., events.example.com/PKF instead of events.example.com/c/PKF).
• Custom Domain Homepage Redirect: You can now configure a Homepage Redirect URL for your custom domain (e.g., calendar.example.com). Instead of showing a generic 404, visitors to your domain root will be sent to the specific URL you configure (or a helpful 404 if none is set).
• Improved Calendar Subscription Trigger: We've improved the subscription experience with an automatic calendar app trigger (for Apple and Outlook Desktop). If the automatic trigger fails, we now provide comprehensive manual import guides for all common calendar applications.
• Configurable External Sync Settings: Events imported from external calendars now benefit from smart configuration. We automatically apply your configured default RSVP and email reminder settings to newly imported external events, saving you manual setup time.

You can now host your event and calendar pages on your own custom domain (e.g., events.yourcompany.com or schedule.mybrand.co).

This Business plan feature ensures full brand consistency and trust across every touchpoint.

Custom Domain Use Cases:

• White Labeling: Deliver a completely branded experience where visitors never leave your domain, removing all third-party branding.
• Brand Trust: Use a recognizable subdomain to increase user confidence in registration and subscription links.
• SEO & Tracking: Maintain maximum SEO benefit and tracking consistency by keeping all your content under one root domain.

We've extended the power of our custom field system to your calendar subscription pages!

You can now use Custom Subscription Forms to collect any additional information you need from visitors when they subscribe or follow your calendar. This brings all the flexibility of the RSVP form builder—including text fields, dropdowns, and marketing consent—to your subscriber management.

We've also added the ability to export your calendar subscribers, making it easy to integrate your audience data with external CRM or marketing systems! This gives you complete control over the data you collect and how you use it.

This month, we focused on delivering significant incremental improvements across the platform, including squashing lots of pesky bugs 🐞, to ensure a smoother experience as we prepare for some big features coming soon!

Here are the key enhancements rolled out:

• API Event Filtering: You can now search and filter events programmatically using our updated API, giving you the power to build dynamic and responsive applications.
• Delete Calendar Subscribers: Gain better control over your audience by having the option to delete calendar subscribers directly, which allows for a cleaner list management process than simply blocking.
• Granular Series Management: For those using Event Series, you can now delete a specific individual event from the series without disrupting the recurring schedule.
• Addevent Import Upgrades: We've made significant improvements to the import functionality to better support and map native features when migrating events from Addevent.
• Custom RSVP Button Text: Personalize your event pages by customizing the text on the main RSVP button (e.g., change "RSVP Now" to "Register Here").
• RSVP Button Control: Enhance attendee focus by configuring your custom RSVP forms to hide the 'Maybe' and/or 'Can't Go' buttons, simplifying the response choices.

We've revolutionized how recurring events work with our new Event Series system. This major upgrade replaces the old event recurrence approach with a more intuitive and flexible way to manage your repeating events.

Unlike traditional recurring events, each event in a series is a real, standalone event that can be customized independently.

Key Advantages of Event Series

• Individual Event Customization: Modify any event in a series without affecting other instances. Change the location for a single meeting or add special details to a holiday event with ease.
• Independent RSVP Management: Every event in a series has its own unique RSVP list, attendee tracking, and capacity limits.
• Perfect External Calendar Sync: Event Series solve common sync issues by ensuring each event syncs perfectly as an individual calendar entry, eliminating conflicts and ensuring perfect integration with Google, Outlook, and other calendars.

Plus, some other improvements:

• Per-event RSVP: Now available for all events in a series.
• Improved External Calendar Sync: Overall reliability and speed have been significantly boosted.
• Date Filtering via API: You can now filter events by date when using our API.

We've improved how recurring events are handled, giving you and your visitors more control over which events are added to their calendar.

• Selective Event Imports: When a visitor clicks the "Add to Calendar" button for a recurring event on both the event page and calendar page, they can now choose to add just the next upcoming occurrence or all future occurrences of the event. This allows them to keep their personal calendars clean while still staying up-to-date.
• Improved Recurrence Display: Event pages now clearly show recurrence details, such as "Weekly on Thursday" as well as the date of the next upcoming recurrence. This helps visitors easily understand the event schedule.

We've upgraded our analytics engine to provide you with more accurate and powerful insights. Our new filtering system now automatically detects and excludes bot clicks, including those from email security checkers and other services that mimic browser behavior.

This change ensures that your traffic data is cleaner and more reflective of real human engagement. Your analytics should now be even more powerful and reliable.

If you notice any unexpected changes or have questions about the data, please don't hesitate to contact our support team.

We've implemented Server-Side Rendering (SSR) for your AddCal event and calendar pages, significantly boosting performance. This technical enhancement means faster load times, improved SEO through better search engine indexing, and more consistent performance across all devices. This upgrade delivers a foundational improvement for both your visitors and search engines.

We're excited to introduce a powerful new Spreadsheet Import feature, allowing you to bulk upload events into your AddCal calendars using CSV or XLSX files!

Key capabilities include:

• Bulk Upload: Easily import a large number of events by uploading your CSV or Excel file.
• Flexible Field Mapping: Map columns from your spreadsheet to event fields like Title, Description, Location, Start Date, End Date, Timezone, and more.
• Pre-Import Review: Get a comprehensive preview to review and adjust your column mappings before finalizing the import.

We're excited to introduce Automated Email Reminders for your events, a powerful new feature designed to boost attendance and keep your registered attendees informed! Now, event organizers on Business plans can automatically send timely reminder emails to their RSVP attendees before events begin.

Key features include:

• Flexible Timing Options: Set reminders to send days or hours before your event (e.g., 1-7 days, 1-23 hours, or a combination).
• Smart Processing: Reminders are sent automatically in the background, only once, and only for active, upcoming events.
• Professional Emails: Reminder emails match your event branding, include event details, and attach a calendar file (.ics) for easy adding to attendees' calendars.

We're excited to introduce Event Tagging and Pinning, giving you more control over how your events are organized and highlighted!

• Event Tagging: You can now assign custom tags to your events. This allows for better categorization and organization, making it easier for you and your users to find specific types of events.
• Event Pinning: Highlight important events by "pinning" them. Pinned events will appear at the top of your event lists, ensuring they get maximum visibility regardless of their date.
