: Starting with v5.40, Microchip replaced the aging 32-bit MPASM with the new pic-as assembler (integrated into the XC8 compiler). Projects written in traditional MPASM syntax will not compile in versions newer than 5.35 without extensive code migration.
MPLAB X IDE 5.35 represents a stable, well‑understood point in Microchip’s IDE evolution. While newer versions bring performance improvements and support for the latest microcontrollers, v5.35 continues to serve a vital role for developers who require 32‑bit operating system compatibility, support for legacy programming hardware, or a development environment with a proven track record of stability.
Released in early 2020, version 5.35 is the final iteration of the MPLAB X IDE to include the . Subsequent versions (v5.40 and later) transitioned to the PIC-AS assembler, which follows different syntax and integration rules. For engineers maintaining "legacy" codebases written in absolute or relocatable assembly for 8-bit PIC® microcontrollers, v5.35 is the most stable and modern environment that still natively supports their original source files without requiring extensive porting.

All compilers can be downloaded from the same Microchip Downloads Archive used for the IDE. Once installed, MPLAB X IDE will automatically detect them and make them available when configuring your project’s build properties. : Starting with v5
The transition after v5.35 marked a significant shift in Microchip's software architecture:
If you are running a very new version of macOS (Catalina or later), note that v5.35 might require 32-bit emulation support, as older versions were not entirely 64-bit. support for legacy programming hardware
