Line 
12.4.2:
2 * sh_tiger0.c: checksum functions return length of file hashed,
3 needed to fix GrowingLogfile bug (researched by
4 siim at p6drad dash teel dot net)
5 * sh_static.c: fix more 'label at end of compound statement'
6 (SH_MUTEX_UNLOCK closing brace; reported anonymously)
7 * make sh_hash.c thread-safe

17 * security fix: regression in the seeding routine for the PRNG
18 (detected by C. Mueller)
19 * regression test added for PRNG seeding routine
