Microchip has moved on to MPLAB X IDE v6.x, but many engineers revert to v5.35. Here’s a comparison:

| Feature | MPLAB X v5.35 | MPLAB X v6.x | | :--- | :--- | :--- | | Stability | Excellent (mature) | Good (but frequent point releases) | | Legacy Debugger Support | Full (PICkit 3, ICD 3) | Dropped/Partial | | Java Version | Java 8 | Java 17 (bundled) | | Project Migration | N/A (base version) | May require project conversion | | Cloud Features | None (offline friendly) | Telemetry, Microchip Account login | | Build Speed | Fast | Similar (marginally faster with SSD) |

Verdict: If you are starting a brand-new design with the latest PIC devices (e.g., PIC18-Q series, PIC32MZ-W), use v6.x. If you are maintaining a legacy product with older chips or debuggers, download MPLAB X IDE v5.35 and freeze your environment.
