Here is the work done for version 0.7 of IWLA (Intelligent Web Log Analyzer witten in Python) since one year and a half :

Core

• Awstats data updated (7.9)
• Remove detection from awstats dataset for browser

• Remove all trailing slashs of URL before starting analyze
• Improve page/hit detection
• Main key for visits is now "remote_ip" and not "remote_addr"
• Add IP type plugin to support IPv4 and IPv6
• --display-only switch now takes an argument (month/year), analyze is not yet necessary
• Add --disable-display option

Plugins

• Geo IP plugin updated (use of ip-api.com)
