# Release Note v5.3⚡

**Release Date:** June, 18 2026

This v5.3.0 release introduces major enhancements in connectivity and import management, a global modernization of the technical stack, as well as significant performance optimizations for data exploration (ZDE).

## 🚀 What's New in v5.3.0?

### 📁 Connectivity & Import Management (ZSA / ZSAJ / ZUP)

The data collection and file integration architecture has been entirely redesigned to offer greater flexibility, robustness, and visibility.

- **New Native Connectors:** Full support for **FTP, SFTP, FTPS, and AWS S3** protocols, now natively integrated into the Connector/Parser system. This includes *graceful shutdown* management and file listing capabilities during connection tests.
- **File Import Interface V2:** A brand-new user interface to simplify file uploads and tracking.
- **Enhanced History & Logs:** Added a detailed file import history per table , a color-coded log viewer for connectors/parsers , and a retry mechanism when dealing with empty connector logs.

### 📊 Zetaly Dataset Explorer (ZDE)

Several key improvements optimize the data exploration experience and performance when handling large volumes of data:

- **Performance Optimization (Count):** To speed up both the user interface and API response times, the system now uses a **dataset lines count estimate** instead of executing heavy `count(*)` queries.
- **Timezone Management:** You can now select and apply a specific timezone for data display, downloads, and query execution.
- **Default Time Filter:** Added and set by default a **"Last hour time frame"** filter.
- **Query Import / Export:** Easily export and import custom query definitions directly within the platform.

### 🔐 Security & User Experience

- **Access Pages Redesign:** Complete overhaul (V2) of the **Login / Register** page for an improved user experience.
- **API Documentation:** Rolled out a new, streamlined **Swagger API Page V2** to simplify third-party integrations and development.

### 🛠️ Technical Core Evolutions

- **Java 25 & Quarkus:** Major infrastructure upgrade to **Java 25** and alignment with **Quarkus 3.33.2** for improved performance and reinforced security.
- **Modular Architecture:** Split all core suite application modules (*ZDE, ZSA, ZUP, ZQM, ZHB, MYZ, ZRP, ZSC, ZSI*) into distinct sub-modules to optimize ongoing maintenance and deployments.
