Latest version (0.6.12) can be found here:
All .exes are clean according to latest release of AVG anti-virus

nskill.exe - just copy over the existing nskill.exe file in c:\program files\nskill

0.6.12 fixes a localisation bug. NSkill now works in most western languages with no messing about with extracting files.

Tidied up the con sheet (shouldn't get a tonne of half-hidden figures showing up now)

All new characters are capped by default

Character sheet shows base values in brackets after each skill (mini sheet doesn't - it's just for showing off, not giving a full setup)

Speeded up some common functions

Program now uses fractionally less memory

New background images of the DoY HQs for that little edge of nostalgia

Some tooltips added (more to come)

Behind-the-scenes work made for a character setup db

More behind the scenes work for auto-updating items

Head implant graphics taken from a random bank

Nanite values showing correctly on the char sheet

Shields can now be used to model psi better - removed nanite cap, char sheet fixed up to reflect psi protection.

Nskill057.exe
0.5.7 changes

DJ's con resists implemented for con resist < 120 Curiously, 0.1% is the resist for 0 points specced. This is not a bug!

Double-click imps to choose them from the implant chooser

Added more psi boosters (still missing the blessed resist spells, will get those next time I have access to an anti)

Shields can be used to model psi shields more effectively

Added the Jones Barter Chip <3

Proto-type of custom classes added (PAs, items with class restrictions, etc. don't work though, nor does saving custom classes)

0.5.6 Changes

PA malus sorted

Couple of sexy resist backgrounds added

Tidying up here and there

Neatened up mini resists

New way of choosing implants (more clicks, but less scrolling)

Option to unlock the spinners, type in high values at your own risk!
           - advanced - read only spinners

Prep for using an xml feed for item listings (makes no sense various people keeping various databases)

Updated known issues

Sorted out the versioning mess - we're now at V0.5.5 and we will go up steadily!

Removed the 12 shield limit (to let people properly model psi shields as they like)

Some more localisation pap

Web functionality not yet complete

No new items!
