What is OpenCATS?
OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.
What is Tanda?
Tanda locks bank-detail edits to payroll staff and seals payslips against tampering.
Tanda's workforce and payroll platform shipped a run of payroll controls and HR integrations in a week. Managers can no longer edit employees' bank details, payroll officers can be limited to specific company files, and payslips now carry a QR seal that lenders can verify. It also added Word contract templates for AU and NZ, an ANCC police-check integration, and a notice on the Clerks Award working-from-home variation.

OpenCATS
6.3HR
OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
◆ Current state
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.
◆ Where it's heading
OpenCATS is undergoing a systematic modernization of its technical foundation: InnoDB migration (v0.10.0), PHP 8 + utf8mb4 (v0.11.0), security hardening (v0.11.1). The project is not adding net-new capability so much as making what exists maintainable and secure enough to run in modern environments. The expanded contributing documentation and automated legacy database testing signal that maintainers are investing in the contributor pipeline.
◆ Prediction
After the modernization sprint, the next likely move is a modern email/rich text editor replacement (CKEditor 4 was pinned at the final open-source release as a placeholder) and further security audit work on endpoints that haven't been touched since the v0.9 era.
Tanda
7.5HR
Tanda locks bank-detail edits to payroll staff and seals payslips against tampering.
◆ Current state
Tanda's workforce and payroll platform shipped a run of payroll controls and HR integrations in a week. Managers can no longer edit employees' bank details, payroll officers can be limited to specific company files, and payslips now carry a QR seal that lenders can verify. It also added Word contract templates for AU and NZ, an ANCC police-check integration, and a notice on the Clerks Award working-from-home variation.
◆ Where it's heading
Tanda Payroll is getting the access controls and fraud protections that larger and franchise employers expect, alongside steady award compliance updates. Hiring and onboarding keep gaining integrations, such as SMS in Hire and police checks.
◆ Prediction
Expect more permission scoping in payroll and further verification or compliance features built on the payslip seal.
