It seems that I am no longer able to release a sustained note in playback in the SFX editor using the 'A' key. A colleague on the Discord server mentioned:

Packbat:
"Checking old versions on my hard drive, it releases the sample in 0.2.0i and doesn't in 0.2.4"

The functionality stopped for me a couple versions ago, personally.

Operating System: Linux Mint 19.3
PICO-8 Version: 0.2.4b

Is this a bug, or a revoked feature?
Thanks in advance.
