--disable-transparent option is gone without the ChangeLog record
It disappeared somewhere between 0.2.8.11 and 0.2.9.9. The last mention of transparent proxy in ChangeLog was for 0.2.7.6.
ChangeLog should document all essential interface changes, both user-facing and build-facing.
The configured define USE_TRANSPARENT is still present in code, but it's initialization has changed in undocumented way.
