I noticed some bugs in version17.4, maybe you did too. If not, here they are:
-Sometimes there were rounding errors which caused the wrong release values on the processing display.
-End limiter release didn't change in the processing core.
-End limiter attack and release weren't loaded when changing preset.
-After changing the preemphasis setting, it wasn't stored.
-The AM clipping wasn't shown.
17.5 will fixed these problems.
If nothing else comes up 17.5 will be released somewhere next week.
