What is Element X Android?

Monthly Matrix client releases grinding steadily toward call and location parity

Element X Android ships on a predictable calendar train (v26.05 through v26.08), each release a mix of one or two user-facing features and a long tail of fixes. The two threads that actually move are Element Call integration and live location sharing, both of which graduated from feature flags in May and have been getting incremental polish since. Accessibility work has been unusually heavy for a client at this stage, with a dedicated TalkBack and screen-reader pass in v26.07.1.

What is Stalwart?

Stalwart is chasing mail RFCs and its own storage layer at the same time

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

Element X Android vs Stalwart: editorial side-by-side

E5.0

Monthly Matrix client releases grinding steadily toward call and location parity

◆ Current state

Element X Android ships on a predictable calendar train (v26.05 through v26.08), each release a mix of one or two user-facing features and a long tail of fixes. The two threads that actually move are Element Call integration and live location sharing, both of which graduated from feature flags in May and have been getting incremental polish since. Accessibility work has been unusually heavy for a client at this stage, with a dedicated TalkBack and screen-reader pass in v26.07.1.

◆ Where it's heading

The team is converting flagged experiments into default behavior and then hardening them rather than opening new fronts. Calls are becoming first-class timeline objects — active call rendering in v26.08.0, active participants surfaced in the people list in v26.08.1 — and location sharing is picking up the notification plumbing (MSC4505) it needed to be usable outside the app. QR code login and device linking sit in the visible 'In development' section across several releases, which is the clearest signal of what lands next.

◆ Prediction

Expect QR code login and the protected device-linking flow to exit the in-development section and ship as defaults within the next one or two monthly releases, with call presence continuing to spread into more surfaces.

S5.0

Stalwart is chasing mail RFCs and its own storage layer at the same time

◆ Current state

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

◆ Where it's heading

Two threads run through every release. One is RFC coverage across IMAP, JMAP, CalDAV and WebDAV, implemented close to the specification including drafts. The other is a long tail of protocol-conformance fixes, many of them cases where JMAP and IMAP disagreed about the same state. The newest release adds a third: memory and scheduling limits, which is what a server codebase starts doing when deployments get large enough for defaults to hurt.

◆ Prediction

Expect continued RFC additions across the JMAP and IMAP surfaces, with more of the storage-tuning work that v0.16.18 started as RocksDB deployments scale.
