What is SuperTokens?

SuperTokens is hardening SAML and building a migration path off other auth providers.

SuperTokens is an open-source authentication service, and its core repo is running a 12.0 canary line alongside stable patches. The work in this window falls into two piles: SAML security — XML signature wrapping protection in 12.0.2-canary, further hardening in the 12.0.10 release — and migration mode, where new core-user-data records can be created as MIGRATED and the transition is now blocked while inconsistent users exist. Release notes are thin, usually a PR title or two per tag.

What is WPML?

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

SuperTokens is hardening SAML and building a migration path off other auth providers.

◆ Current state

SuperTokens is an open-source authentication service, and its core repo is running a 12.0 canary line alongside stable patches. The work in this window falls into two piles: SAML security — XML signature wrapping protection in 12.0.2-canary, further hardening in the 12.0.10 release — and migration mode, where new core-user-data records can be created as MIGRATED and the transition is now blocked while inconsistent users exist. Release notes are thin, usually a PR title or two per tag.

◆ Where it's heading

Migration mode plus account-linking exploration is the tell: this is infrastructure for importing an existing user base from another provider without breaking identity linkage mid-flight, and the guard added in 12.0.5-canary shows they hit the inconsistent-state case in practice. The SAML work runs in parallel because enterprise SAML is what a team is usually migrating toward. Also worth noting: an automated contributor, supertokens-agent-runner, opened its first PRs in this window, so part of the fix and test volume is now agent-authored.

◆ Prediction

A stable 12.x release consolidating the canary migration-mode work is the readable next step, likely once the MIGRATED transition guards have run without incident. More SAML hardening should be expected given two separate fixes landed in this window alone.

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

◆ Current state

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

◆ Where it's heading

Two clocks again. The maintenance clock is dictated entirely by other people's releases: WordPress majors, PHP versions, Divi 5, Elementor. Enough of this feed is compatibility that it reads as the real cost of being a translation layer inside someone else's ecosystem. The product clock points one direction, toward automation — cost and time estimates before sending content, one-click recovery for stuck jobs, automatic detection of custom Elementor widgets, and now automatic translation as the starting state rather than an option. The 4.9.7 security hardening is worth noting alongside a beta in flight: the stable line still gets real attention.

◆ Prediction

Expect the 5.0 line to move from beta to production with the automatic-first defaults intact, followed by continued compatibility maintenance as WordPress core and major builders evolve.
