What is OpenCATS?

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

What is Frappe HR?

Frappe HR runs a dual v15/v16 release train, deepening payroll and recruitment modules.

Frappe HR, the open-source HRMS, ships frequent tagged releases on two tracks: a v15 stable line (mostly bug fixes) and a v16 development line accruing features. Recent work concentrates on payroll correctness — Employee Advance handling, salary components, income-tax reporting — plus recruitment additions and steady permission hardening across forms and reports.

OpenCATS vs Frappe HR: editorial side-by-side

O2.5

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

◆ Current state

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

◆ Where it's heading

The pattern is a community project moving in slow, security-conscious increments: authenticated attachments and earlier XSS/cookie hardening show steady attention to securing an aging codebase. v0.10.0 suggests renewed maintenance momentum rather than a feature pivot.

◆ Prediction

Expect continued infrequent releases focused on security hardening and PHP-version compatibility. A jump in cadence would be the signal to watch for renewed active development.

F5.0

Frappe HR runs a dual v15/v16 release train, deepening payroll and recruitment modules.

◆ Current state

Frappe HR, the open-source HRMS, ships frequent tagged releases on two tracks: a v15 stable line (mostly bug fixes) and a v16 development line accruing features. Recent work concentrates on payroll correctness — Employee Advance handling, salary components, income-tax reporting — plus recruitment additions and steady permission hardening across forms and reports.

◆ Where it's heading

The v16 line is where direction shows: a new Job Applicant hiring-pipeline board, resume uploads on applications, regional payroll rules, and richer advance/expense reporting. The pattern is deepening the payroll and recruitment modules while tightening role-based permissions. Expect v16 to keep absorbing features while v15 stays maintenance-only.

◆ Prediction

Next likely moves: continued v16 feature releases extending recruitment (building on the hiring-pipeline board) and payroll edge cases, with v15 receiving backported bug fixes only.
