| Metric | v48 (pre-hot) | v48 Hot | |--------|---------------|---------| | Avg validation time (50MB instance) | 48 seconds | 52 seconds (due to added checks) | | Memory footprint | 1.2 GB | 1.4 GB | | Max instance size supported | 120 MB | 100 MB (hard limit imposed) | | Concurrent sessions | Unlimited (unstable beyond 5) | Throttled to 8 (stable) |
Note: The hotfix reduces maximum allowed instance size from 120MB to 100MB to prevent XML parser DoS. Filers with large attachments must split or compress footnotes.
Cause: Your instance document includes a concept that requires a dimensional context (e.g., segment-wise sales) but the hypercube relationship is missing.
Fix: Open the tool’s "Dimension Debugger" (new in v48 Hot). It highlights the exact axis missing. Add <xbrldi:explicitMember> tags appropriately.
The Version 48 Hot update is not just about bug fixes. It introduces fundamental changes based on the MCA Notification dated March 31, 2024 (and subsequent clarifications). Here are the key highlights:

As of April 2026, Version 4.8 is no longer the latest version. The MCA has since transitioned to Version 5.0 (released in July 2025) and subsequently Version 5.1 (released in March 2026) to support the modernised MCA21 V3 portal. Key Features of Version 4.8
While newer versions are now active, V4.8 was established with these core capabilities:
Taxonomy Support: Specifically designed for Costing Taxonomy 2019 and C&I (Commercial and Industrial) Taxonomy 2016. Old flow (v48) → Upload instance → Engine
Compliance Checks: Validates that documents meet all Business Rules and taxonomy requirements before submission under Section 137 of the Companies Act, 2013.
PDF Generation: Automatically creates a human-readable PDF version of the XBRL document for final verification and certification.
Error Detection: Preemptively identifies data entry mistakes and missing mandatory elements to reduce filing rejections. Important Filing Requirements Error in XBRL Validation Tool - Google Groups
