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 Spike?
Spike grinds out incident-management ergonomics — number-comparison alerts, more integrations, broader AWS auto-resolution.
Spike is an incident management and on-call platform competing in PagerDuty's category. The recent quarter's releases are uniformly incremental — numeric comparison operators in Alert Rules, broader AWS auto-resolution coverage (now including SNS), Jenkins and NinjaOne integrations, an inbound Jira trigger, day-of-week alert routing, admin-managed Out of Office. Each release shaves friction from a specific operator workflow without changing what Spike fundamentally is.

◆ 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.
Spike
0.0COMMS
Spike grinds out incident-management ergonomics — number-comparison alerts, more integrations, broader AWS auto-resolution.
◆ Current state
Spike is an incident management and on-call platform competing in PagerDuty's category. The recent quarter's releases are uniformly incremental — numeric comparison operators in Alert Rules, broader AWS auto-resolution coverage (now including SNS), Jenkins and NinjaOne integrations, an inbound Jira trigger, day-of-week alert routing, admin-managed Out of Office. Each release shaves friction from a specific operator workflow without changing what Spike fundamentally is.
◆ Where it's heading
Spike's competitive strategy reads as 'be more methodical about the long tail of operator paper-cuts.' The integration cadence is high — Jenkins, NinjaOne, Jira inbound, calendar links — the alert rule grammar keeps expanding (comparison operators, day-of-week conditions), and the on-call surface keeps gaining flexibility (gaps, scheduled layers, admin-managed OOO). No directional moves, but very consistent incremental velocity.
◆ Prediction
Expect more integration additions in the same vein (CI/CD tools, IT monitoring vendors), continued alert rule grammar expansion (time-of-day conditions and frequency-based thresholds are the obvious next axes), and more team-management features around on-call rotations.
