2.6.0 (2025-08-21)

🚀 Features

• Add better spawn fairness based of available tiles near generals (ba54af5)
• Add grid generation closely resembling official generals.io (6e35fd1)
• Add new environment that can be vectorized and used for self-play (b9e9477)
• Add new move priority system based on official generalsio (e5676c3)
• Allow tensor padding (got for nets) (19ac5c7)
• Grid factory can now pad grids with mountains to a fixed size -> better for neural nets (e622e7a)
• Improve online play (37e706f)
• Make grids more generalsio like (3d5c38f)
• Make sequential processing 40% faster with JIT Numba (3dfd9d6)
• Stack environment information in a different fashion to make it vectorizable (gymnasium) (a9cfea5)
• Tidier online client output, show score (#131) (7ab2dd0)

🐛 Bug Fixes

• Reset prior observations in env.reset() as well (df3bdc2)
• Simultaneous general capture fix (0cfb535)

🛠️ Refactor

• Consolide rewards into one file (90afca6)
• Flatten info dictionary for vectorized environments (5caac61)
• Improve grid class in efficiency and readability (8230672)
• Make observations slightly more memory efficient (c591d29)
• Move padding responsibility from grid to Observation (1a42e87)
• Move rewards to info dict for gymnasium (f3151b3)
• Option to pad observation separately (a3d7861)
• Pass only agent names to environment, this is better with libs (ac39647)
• Remove AgentFactory as it is a useless construct (a50bea0)
• Remove optional colors, as it is a useless construct (7c87c34)
• Return info dict right after reset (1156440)
