Delta Chat vs RSS.com: at a glance
What is Delta Chat?
Delta Chat is quietly replacing its email identity with relays
Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.
What is RSS.com?
RSS.com's changelog is back after ten months, with listener voicemail for podcasts.
RSS.com is a podcast hosting platform. After a public API in December 2025 its changelog went silent until v26.10.1 in October, which lets listeners leave voicemails for a show through a link in the episode notes. Earlier releases added Podcasting 2.0 location tags and a year of analytics lookback.

Delta Chat is quietly replacing its email identity with relays
◆ Current state
Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.
◆ Where it's heading
The project is removing email from what users see and from how they think about identity, with relays taking its place as multi-path infrastructure. Fetching from every relay and sending through the fastest one treats a relay as replaceable, which matters for a federated messenger. Around that, the client keeps closing feature gaps with mainstream messengers through pinning, channel reactions and better group notification handling.
◆ Prediction
Expect further relay management work, as the core notes show this is where the structural change is. Channels are the next most active surface, with reaction privacy already changing there.
RSS.com
2.5COMMS
RSS.com's changelog is back after ten months, with listener voicemail for podcasts.
◆ Current state
RSS.com is a podcast hosting platform. After a public API in December 2025 its changelog went silent until v26.10.1 in October, which lets listeners leave voicemails for a show through a link in the episode notes. Earlier releases added Podcasting 2.0 location tags and a year of analytics lookback.
◆ Where it's heading
The October release points toward listener interaction rather than the developer and metadata work of late 2025. One entry after a long gap is too little to call a new direction.
◆ Prediction
Unclear: a single release after ten quiet months doesn't establish a cadence, so the next move can't be read from the entries.
