✨ New in VRS 14.12.1

This patch builds on VRS 14.12.0. It focuses on recording reliability, Media Recordings usability, archival playback accuracy, offline-friendly UI assets, and clearer on-screen feedback.

Media Recordings

Feature(s)	Description
EFCX Agent Name dropdown	On EFCX, Agent Name in the Media Recordings advanced filter was previously free text with no agent dropdown. From 14.12.1 it is a dropdown so users can find and select an agent name. Cisco Agent Name remains free-text.

Archival and playback

Feature(s)	Description
Multi-leg archival — correct audio per leg	Archival stamps each uploaded file with its own archive path. Playback prefers that stamp (basename must match the requested leg) so sibling legs cannot play each other’s archived audio after local files are removed.

Platform

Feature(s)	Description
Local Material Icons (no Google CDN)	Material Icons fonts are bundled under application assets. The UI no longer depends on `fonts.googleapis.com` / `fonts.gstatic.com`, so icons render on offline or LAN-only deployments.
Login account lockout (Keycloak Brute Force Detection)	After too many wrong passwords, Keycloak can temporarily lock the account. VRS shows `Account is locked. Try again later.` when the account is locked, and `Invalid username and/or password` otherwise. Same behavior on Cisco and EFCX when Brute Force Detection is enabled on the realm used for VRS login. Admins unlock in Keycloak (Temporarily locked Off and Enabled On).

Cisco linking reliability

Feature(s)	Description
JTAPI linking indexes, retries, and recovery	Schema indexes for Mixed_Sessions / call_events lookup columns; JTAPI deadlock retries with backoff; periodic late re-link for orphan rows; warm-start of in-memory call state after JTAPI restart. Reduces recordings that stay unlinked (`correlation_id` `0`, missing JTAPI / direction).

Improvements

Improvement	Description
UI feedback improvements	Clearer on-screen status for WAV/MP3 download (`WAV downloading…` / `MP3 downloading…`) and clearer login messages that distinguish invalid credentials from a temporary account lock.
