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 Tanda?
Tanda lets managers pick who can claim a vacant shift and adds bulk availability approvals.
Tanda's workforce and payroll platform ships rostering, HR and payroll controls in near-daily batches. On 11 and 12 November managers gained a choice of who can claim a vacant shift, bulk approval of availability requests, a roster publish menu that remembers settings, and skills ratings inside performance reviews. Payroll got team-level journal accounts for split autopay salaries, and the old wage comparison report was retired in favour of Wage Compare.

◆ 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.
Tanda
7.5HR
Tanda lets managers pick who can claim a vacant shift and adds bulk availability approvals.
◆ Current state
Tanda's workforce and payroll platform ships rostering, HR and payroll controls in near-daily batches. On 11 and 12 November managers gained a choice of who can claim a vacant shift, bulk approval of availability requests, a roster publish menu that remembers settings, and skills ratings inside performance reviews. Payroll got team-level journal accounts for split autopay salaries, and the old wage comparison report was retired in favour of Wage Compare.
◆ Where it's heading
After a 4 November HR Agent beta and SMS in Hire, the latest batch is about cutting manager clicks in scheduling and approvals. Several changes consolidate older tools, such as the retired wage report and the redesigned publish menu, which points to a cleanup of the rostering surface alongside new HR features.
◆ Prediction
The redesigned roster publish menu is due to go live this week, and more consolidation of older reports and menus is likely; the entries do not show the HR Agent beta's next step.
