How to update a package?

Question

PHP

I'm trying to update the liip/imagine-bundle.
I'm looking at changes in github - a new $tempDir parameter has appeared , this parameter would be very useful, so I decided to update.
Composer.json says "liip/imagine-bundle": "^1.6"
I type the most common command: composer update liip/imagine-bundle
The operation is successful.
I look at the JpegOptimPostProcessor.php file, there is no new parameter. O_O
What did I do wrong?
Tried uninstalling and reinstalling. Same result.

To begin with, send traffic from Composer through a sniffer and see where it comes from, and if this change is not there anywhere, then only manually.
