What is Proton Bridge?

Proton Bridge spends its first release in ten weeks on crashes, memory bounds and dead code

v3.26.0 is a maintenance cut. The user-visible items are a macOS 27 crash fix, bounded CPU and memory in the Gluon RFC parser, deletion of orphaned unencrypted vaults once keychain access returns, and a meta+W shortcut. The rest is internal: two unused subsystems removed from go-proton-api, two Go toolchain bumps, gomock swapped for uber-go/mock, and June and July vulnerability patches folded in.

What is Zoho Mail?

Zoho folds its transactional email product into the mailbox and hands out free credits

The feed mixes real product changes with governance thought-leadership, and this window has one of each: ZeptoMail, Zoho's transactional email service, is now presented as part of Zoho Mail and Workplace with starter credits, following Web Tabs pinning arbitrary websites inside the mail client. The rest is positioning — a phishing narrative used to walk through the rules engine, an admin console overview, and Microsoft's EWS retirement written up as a migration prompt. Email journaling remains the substantive enterprise capability in the set.

Proton Bridge vs Zoho Mail: editorial side-by-side

P2.5

Proton Bridge spends its first release in ten weeks on crashes, memory bounds and dead code

◆ Current state

v3.26.0 is a maintenance cut. The user-visible items are a macOS 27 crash fix, bounded CPU and memory in the Gluon RFC parser, deletion of orphaned unencrypted vaults once keychain access returns, and a meta+W shortcut. The rest is internal: two unused subsystems removed from go-proton-api, two Go toolchain bumps, gomock swapped for uber-go/mock, and June and July vulnerability patches folded in.

◆ Where it's heading

Releases arrive in long gaps — ten weeks since v3.25.0 — and each one bundles a quarter of dependency hygiene with a handful of IMAP correctness fixes. The recurring theme is RFC 3501 conformance and resource bounds in the mail parser rather than new capability, which is what a local IMAP shim for an encrypted mailbox is supposed to look like.

◆ Prediction

Given the pattern of shipping OS-compatibility fixes shortly after a macOS release, the next cut is likely another maintenance bundle timed to whatever the current macOS version breaks.

Z6.3

Zoho folds its transactional email product into the mailbox and hands out free credits

◆ Current state

The feed mixes real product changes with governance thought-leadership, and this window has one of each: ZeptoMail, Zoho's transactional email service, is now presented as part of Zoho Mail and Workplace with starter credits, following Web Tabs pinning arbitrary websites inside the mail client. The rest is positioning — a phishing narrative used to walk through the rules engine, an admin console overview, and Microsoft's EWS retirement written up as a migration prompt. Email journaling remains the substantive enterprise capability in the set.

◆ Where it's heading

Zoho keeps widening what the mailbox contains rather than improving mail itself. Web Tabs pulled other applications into the window; ZeptoMail pulls the machine-generated side of email — password resets, OTPs, order confirmations — under the same roof as human correspondence. The direction is a single console covering both what staff send and what applications send, with the enterprise controls (rules, journaling, admin reporting) as the procurement argument.

◆ Prediction

Expect the two mail paths to converge in tooling — shared domain and deliverability configuration, unified reporting across human and transactional sending. The free credits read as a conversion mechanism, though the entries say nothing about pricing once they run out.
