Problem with specifying filtering expression v1.21

[reshu23]

Dear Team,
I am using bcftools 1.21. I have noticed, in this version, I can not use space between filtering expression. For example: when I tried bcftools stats -i 'QUAL>8 && DP>=10', It was not working. When I removed space between QUAL && and DP, It worked. Here is the screen shot: Is it the expected behavior of 1.21.? Thank you.
