Here it finally is. Version 1.0b is released!
The complete changelog (can also be viewed in the description):

• Optimization: Much more cleaner, accurate and responsive script. It reacts up to 1 second faster compared to 0.71b! Nearly 300 unnecessary lines were removed and many slow functions were exchanged for faster functions.
• Optimization: Much more accurate archery-detection. The script now knows where you shot your arrow and can even calculate the gravity affecting the arrow!
• New feature: Percentaged damage with new multipliers for it in the config-file. If you don't want this feature, set them to 0; if you want e.g. instant-kills with every shot to the head, set the multiplier for the head very high. There are multipliers for melee and archery.
• New feature: New effects, marked with "(NEW)" in the list in the description.
• New feature: New config-setting "useUndeads".
• Feature change: Bodyzones "Right foot" and "Left foot" combined to bodyzone "Foots".
• Feature change: Removed block-features. They were useless and had nothing to do with locational damage.
• New requirement: SKSE.
• Fixed bug: Disabled criticals if target lays on the ground.
• Fixed bug: Brawls are now playable if neither a weapon nor magic is equipped.
