What is OpenCATS?
OpenCATS starts a Bootstrap 5.3 interface refresh after a year of modernisation
OpenCATS has spent 2026 rebuilding its foundations: InnoDB and CSRF protection in 0.10.0, PHP 8.4/8.5 and utf8mb4 in 0.11.0, security fixes in 0.11.1. 0.12.0 begins an interface refresh on Bootstrap 5.3 across the main screens, login, installer and Career Portal, replaces Artichow charts with bundled Chart.js and CKEditor with SunEditor, and hardens security in existing workflows.
What is Teamtailor?
Teamtailor shows every time in the reader's own time zone, for recruiters and candidates.
Teamtailor is an applicant tracking system whose AI layer spans MCP access, Co-pilot, Smart action triggers and Meeting insights. This week's releases are workflow fixes: times now display in each reader's own time zone across emails, invites and candidate bookings, job offer templates can carry embedded PDFs, and the candidate card sidebar can be resized. October focused on reusing existing talent with Browse candidates and AI match explanations.

OpenCATS starts a Bootstrap 5.3 interface refresh after a year of modernisation
◆ Current state
OpenCATS has spent 2026 rebuilding its foundations: InnoDB and CSRF protection in 0.10.0, PHP 8.4/8.5 and utf8mb4 in 0.11.0, security fixes in 0.11.1. 0.12.0 begins an interface refresh on Bootstrap 5.3 across the main screens, login, installer and Career Portal, replaces Artichow charts with bundled Chart.js and CKEditor with SunEditor, and hardens security in existing workflows.
◆ Where it's heading
The modernisation has moved from runtime and database to what users see, while keeping the existing models and permissions. Old components are being replaced one by one rather than rewritten.
◆ Prediction
0.12.0 is described as the first step of the refresh, so further interface releases are likely next.

◆ Current state
Teamtailor is an applicant tracking system whose AI layer spans MCP access, Co-pilot, Smart action triggers and Meeting insights.

October focused on reusing existing talent with Browse candidates and AI match explanations.
◆ Where it's heading
After the late-October push on talent rediscovery and API key hygiene, November is filling in day-to-day recruiter friction for distributed teams and the offer stage. The cadence is several small releases a week, each closing one specific annoyance.
◆ Prediction
Expect more offer-stage and scheduling refinements, plus further Co-pilot reach into Browse candidates; nothing in these entries points to a new AI surface yet.
