Deep Alts

Added

• IP hashing using SHA-256 - all IPs now stored as hashes instead of plain text
• Automatic migration from plain IP data to hashed format
• Privacy-focused logging showing only hash prefixes

Changed

• Data storage format: ips → hashed_ips, latest → latest_hashed
• ProxyCache.isProxy() → ProxyCache.checkProxy() returning ProxyResult
• Admin command messages updated for hashed IP terminology

Removed

• /deepaltsconfig clearcache command
• ProxyCache.clearCache() and removeCachedIp() methods

Security

• Original IPs only used for proxy API calls then immediately discarded
• All stored data now uses irreversible SHA-256 hashes
• Protection against IP exposure in data breaches

Migration

• Automatic conversion of existing IP data on first load
• Both main data file and proxy cache migrated
• No manual intervention required

• Added online/offline player colors

• Fixed bug with backwards compatibility

New Features

• Added compatibility for all Minecraft versions 1.20+
• Refactored package names to fit with java conventions

New Features

• /deepaltsconfig Admin Command

  • Added full support for /deepaltsconfig with the following subcommands:

    • /deepaltsconfig status – View plugin state and cache size
    • /deepaltsconfig rebuild – Rebuild the alt graph from IPs (excluding proxy IPs)
    • /deepaltsconfig clearcache – Clear the proxy detection cache
    • /deepaltsconfig save – Force save all plugin data
    • /deepaltsconfig reload – Reload data from disk
    • /deepaltsconfig info – Show detailed statistics and graph metrics

Proxy Detection & Filtering

• Integrated IP-API to detect proxy and hosting IPs:

  • IPs marked as proxy or hosting are excluded from graph connections
  • Responses are cached for performance and to reduce API calls
  • API rate limits (X-Rl, X-Ttl) are respected to avoid bans

Structural Refactoring

• Graph logic extracted into its own class (DeepAltsGraph)

  • Improves maintainability and future extensibility
  • Easier to add new connection logic (e.g. shared usernames, hardware IDs, etc.)
