Dave Yeo has released an unofficial "IME" build
of SeaMonkey 2.7.2 (8/2/2012) from the Gecko 10.0.6 "Extended Support
Release" branch. SeaMonkey does not officially support ESR builds,
which is why only the internal / Gecko version number has changed.
Compared to earlier Gecko 10 builds, it now requires libc065, and
includes some miscellaneous OS/2 fixes, such as the return of proper IME
support for DBCS users. SeaMonkey is a continuation of the Mozilla
Suite. See my Warpzilla Tips page for more information.
