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 Pumble?

A team-chat app whose tracked feed is all comparison SEO, not product changes.

The feed tracked for Pumble is its marketing blog, not a changelog. Every recent post is either a competitor comparison ('vs Rocket.Chat,' 'vs WhatsApp,' 'vs Twist') or a generic team-communication how-to, and none of it reflects shipped product changes. Pumble is CAKE.com's team-messaging tool, positioned as a free alternative to Slack.

Proton Bridge vs Pumble: 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.

◆ Current state

The feed tracked for Pumble is its marketing blog, not a changelog. Every recent post is either a competitor comparison ('vs Rocket.Chat,' 'vs WhatsApp,' 'vs Twist') or a generic team-communication how-to, and none of it reflects shipped product changes. Pumble is CAKE.com's team-messaging tool, positioned as a free alternative to Slack.

◆ Where it's heading

There is no product-development signal to chart here — the cadence measures content-marketing output, not release velocity. The consistent editorial line is bottom-of-funnel comparison content aimed at teams evaluating chat tools against Pumble's free tier.

◆ Prediction

Nothing in these entries supports a product prediction; the feed will keep producing comparison and how-to marketing posts. Tracking actual Pumble releases would require pointing the crawl source at a real changelog rather than /blog.
