Several fixes were recently merged (some GUI problems, build patches on Linux,
new zlib, and security issues), but some other problems are still pending
until a 3.43 release can be ready. Yes, it's about time, but time is hard to
find :p

- the "updating a mirror redownload too much data" bug is hard to reproduce,
if you have reproductible steps, please provide it. none of the tested sites
(including dynamic ones) could raise the problem using latest 3.42 builds ("no
files updates" message at the end of the mirror, even after several
re-updates)

- the "only one connection is sometimes being used" issue is not really a bug,
but a design consequence of the link scanner, which is less parallelized, to
solve complex redirect/mime types issues (such as an html link redirecting to
an image after several loops, and which shall be solved for local filesystem
issues)

- the "many temporary files, especially .delayed files, are left on disk"
should be a 3.41 bug fixed in 3.42 -- please also feel free to provide
reproductible steps if the bug is still sometimes floating around

- ftp handling is still very basic: this is a known limit, and it will not be
fixed in a near future (httrack is focused mostly on www, not ftp)

William will probably spot more pending issues :)
