platformio/toolchain-atmelavr remain at 1.70300.191015 despite latest release is 3.70300.220127

Operating system: macOS 10.13.6

PlatformIO Version (platformio --version): PlatformIO Core, version 6.1.3

Description of problem

I'm trying to use PlatformIO for bare metal development for tinyAVR 2 Series (i.e. ATtiny824, ATtiny3227, etc.), and I get compilation error:

My platformio.ini configuration as:

[env:ATtiny3227]
platform = atmelmegaavr
board = ATtiny3227

A closer examination of the installed version of toolchain-atmelavr shown that it is at 1.70300.191015, which is 3 years old and before Microchip release the tinyAVR 2 series. There were two releases since 1.70300.191015 and the latest version 3.70300.200127 does support the tinyAVR 2 series.

So I delete the toolchain-atmelavr installed on the machine, and when re-run the compilation, it re-install the 1.70300.191015 again and therefore failed the compilation.

Even if I manually download the latest version, the system will still use the older version when compiling the code. It seems that despite that I have the latest PlatformIO Core installed, and the latest framework-atmelmegavr package installed (1.6.0), somehow the toolchain-atmelavr never get updated to the latest release.

I added platform_packages to force the PlatformIO to use the latest toolchain, and every thing works fine.

[env:ATtiny3227]
platform = atmelmegaavr
board = ATtiny3227
platform_packages =
  toolchain-atmelavr@3.70300.220127

I hope this can be fixed in the next release of PlatformIO.

It's expected as the 3.70300.220127 version is meant to be used with the atmelmegaavr dev-platform.
