Compile Size Increased

PlatformIO IDE
1

I wrote a program just over a year ago for an ATtiny13a and it compiled.

I tried to compile it again just now and the compile size has just tipped past the 1024 byte size.

I read another post My PlatformIO Projects Now Compile With Errors And I Cannot Figure Out Why?

This seems to point to my not specifying a platform version in the platformio.ini. Are you able to point me in the right direction so I can use a specific past version?

Also - how do I fix the compile size for my other projects moving forwards?

My platformio.ini

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:attiny13a]
platform = atmelavr
board = attiny13a
framework = arduino


; device is USBASP V2.0 with updated firmware
upload_protocol = custom
upload_port = usb
upload_flags =
    -C
    ; use "tool-avrdude-megaavr" for the atmelmegaavr platform
    ${platformio.packages_dir}/tool-avrdude/avrdude.conf
    -p
    $BOARD_MCU
    -P
    $UPLOAD_PORT
    -c
    usbasp
upload_command = avrdude $UPLOAD_FLAGS -U flash:w:$SOURCE:i

I’m getting closer to a solution - found this post https://community.platformio.org/t/how-to-specify-desired-version-of-an-installed-framework/21970/1

I think I need to use

platform = atmelavr@x.y.z

but where do I find a history of past stable versions to try?

And then I found this https://github.com/platformio/platform-atmelavr/releases

I edited my platformio.ini to include

[env:attiny13a]
; platform = atmelavr
platform = atmelavr@5.0.0
board = attiny13a
framework = arduino

and then did a recompile…
