Blesta 6.0 went out on 4 August 2026 — the company calls it the biggest release since version 3, and the diff backs that up. The admin panel is rebuilt from scratch on Bootstrap 5 under the name Paradigm, there's an optional AI layer woven through Support Manager and reporting, and the upgrade mechanism itself changed to cryptographically signed one-click updates. None of it touches the licensing model — Owned and Leased pricing stays exactly as it was — but if you run custom extensions or a heavily jQuery-dependent theme, this release has a real compatibility checklist attached to it.
The headline change: Paradigm admin UI
The old top-nav admin is gone. Navigation now lives in a left sidebar with a
drag-and-drop icon bar, a new top bar handles search and notifications, and the whole
interface ships with native dark mode — toggleable per-page with one click rather than a
theme swap. The client profile got the same treatment: Ctrl+K opens instant client
search, panels remember their open/closed state between visits, and there's a bulk
actions bar for handling multiple services at once.
Configurable Options — the part of Blesta admins touch most when building packages — now supports drag-and-drop reordering and copy-paste between groups, which previously meant rebuilding option sets by hand for every similar package.
Blesta AI: optional, staff-gated, separate subscription
Blesta AI is not bundled into the core license — it's an add-on that requires its own subscription, starting at a few dollars a month, and it's controlled per staff group so you can restrict it to senior support staff or turn it off entirely. Where it shows up:
- Support Manager — drafts or auto-sends ticket replies above a confidence threshold you configure, adjusts ticket priority, assigns staff, and closes tickets it judges resolved. If you already run Blesta's Support Manager, this is the first release where autoresponses can go out without a human click — worth testing on a low-stakes department before enabling it on billing-critical queues.
- Package and template generation — drafts package descriptions and email templates from a prompt.
- Admin chatbot — writes SQL for custom reports and drafts API calls, aimed at admins who don't want to hand-write report queries.
Previous Blesta AI beta API keys were retired with this release — if you tested the beta, you'll need to re-subscribe rather than reuse an old key.
Real-time notifications and revenue analytics
Orders, tickets, and system events now surface without a page refresh, with an extensibility hook for plugin developers to push their own notifications into the same feed. Separately, Billing > Reports gets a new revenue analytics dashboard built from nightly snapshots: MRR, ARR, ARPU, lifetime value, churn, an MRR waterfall, cohort retention grids, and 12-month renewal projections, all multi-currency-aware. For hosts running multi-currency billing, this is the first built-in view that doesn't require exporting to a spreadsheet to see churn trends.
What breaks: jQuery removal and the extension compatibility list
The technical change with the most blast radius: jQuery is removed from the admin entirely, replaced with vanilla JS. Blesta ships a legacy-support toggle in settings that re-enables jQuery for compatibility, but it's off by default.
If you run custom extensions, custom themes, or third-party plugins that hook into admin JS, check them against this list before upgrading:
- Official first-party extensions are already converted to Bootstrap 5 and Paradigm — no action needed if you're only running Blesta's own provisioning modules like cPanel/WHM auto-provisioning or Plesk provisioning.
- Third-party plugins that inject nav items should declare navigation icons for the new sidebar to integrate natively — plugins that don't will still function but may land in a fallback menu location.
- Anything that calls
$(...)directly in custom JS breaks silently until you either toggle legacy jQuery support back on or port the calls to vanilla JS.
Other technical changes worth knowing before you upgrade:
- Collation —
utf8mb4is now the default, with automatic conversion applied during the upgrade itself. - Redis — available as an optional cache layer for performance, not required.
- Composer — the platform moved to Composer v2; if you manage dependencies for custom modules by hand, update your workflow accordingly.
- PHP 8.2–8.4 — deprecation remediation is complete across this range, so none of these are newly unsupported by the 6.0 codebase.
Signed one-click upgrades
Releases are now cryptographically signed and verified against public/private keys during
the upgrade process itself, and upgrades can be kicked off from inside the Blesta admin
(/admin/upgrade in a browser) or via CLI — you're no longer required to download and
extract a release archive by hand for routine version bumps. Back up your database and
files before running it regardless; that step is still manual and still mandatory. If you
want someone else to run it, Blesta offers paid upgrade assistance at $45 per install.
Should you upgrade now
If you're running a stock install with official provisioning modules and gateways — Stripe, PayPal, the standard panel modules — this is a low-risk upgrade: back up, run the signed upgrade path, and the jQuery removal won't touch you since first-party extensions are already converted. If you run custom-built extensions, a hand-rolled theme, or JS that hooks the old admin, budget a staging-environment test first specifically for the jQuery change — that's the one thing in this release actually capable of breaking a production support queue rather than just looking different. Either way, your Blesta license — Owned or Leased — already entitles you to 6.0 at no extra cost; there's no separate fee to unlock Paradigm.
