## 4.0.2
|
||||||
|
|
||||||
|
This is a production release that fixes two bugs:
|
||||||
|
|
||||||
|
1. If no files are used and the first statement on `stdin` is invalid, `scale`
|
||||||
|
would not be set to `20` even if `-l` was used.
|
||||||
|
2. When using history, `bc` failed to respond properly to `SIGSTOP` and
|
||||||
|
`SIGTSTP`.
