Alloy Chat | Version 1.0.9 | Release Notes

This is the content for Version 1.0.9 of the Alloy Chat for Teams. Release Planned on Jan 31, 2026.

Please be advised that we are currently in the process of rebranding the MultiLine Messaging application and the app name will be updated in coming months.

In MultiLine Messaging version 3.5.0, we introduced advanced attachment capabilities for WhatsApp, including support for images, documents, audio, video, contact cards, and location sharing. However, due to technical limitations within the Alloy Chat application, these advanced attachment features cannot be fully supported in its current version.

To ensure a smooth user experience, Alloy Chat 1.0.9 introduces graceful handling of unsupported attachments, preventing failures or unexpected behavior.

What’s New in 1.0.9

This update allows users to send and receive a broad range of attachments and MIME types. Supported attachments include:

• Images: jpeg, jpg, png
• Documents: pdf, pptx, docx, xls, xlsx
• Contact Card: vcf
• Stickers: Webp
• Audio: mp3, ogg (codecs=opus, aac)
• Voice Notes: ogg (codecs=opus)
• Video: mp4
• Location: Shareable within conversations

Administrators can configure which attachments and MIME types are allowed for their organization through the Movius Management portal. If a specific file type needs to be disabled, administrators can contact Movius Customer Support to request this change. For detailed feature management guidelines, refer to the platform Release Notes 4.57.1. Attachments are also available to be offloaded via the compliance feed, consistent with existing file handling practices.
