All changes between Wt 3.3.7 and 3.3.8 RC1 also apply to Wt 4.0.0 RC1. For changes specific to Wt 4, see the release notes .

Users of JWt need not worry. While there’s no JWt 4 yet, this does not mean we’re abandoning JWt. Most changes in Wt 4 are very specific to C++. We will work on updating our Wt to JWt porting toolchain after the release of Wt 4 so that JWt can stay in sync with Wt.
