Odamex 0.5.3 (r2284)
Odamex 0.5.3 was released on June 24th, 2011.
Features
Emulate vanilla Doom bug: respawning cube-spawned monsters at map location (0, 0). This should fix desync of 30nm4048.lmp
Restored dead player´s view following the actor who killed them.
Bug Fixes
Sometimes players would make a death scream when switching to spectate. Fixed.
Some video modes were duplicated under video mode options. Fixed.
Fixed a crash that would occur when a client attempts to download a wad when the server had sv_waddownload disabled.
Fixed trash information spamming the console when launching odamex from odalaunch under linux.
Players would play the ´oomph´ sound when they landed from jumping in place. Since this is probably vanilla behavior, this was edited for co_zdoomphys since it was particularly noticeable and annoying for CTF.
Player death scream wouldn´t be audible if the player respawned instantaneously. Fixed.
Fixed issues with rightalt, rightctrl, and rightshift showing up as numbers.
Reuse any thinker for a particular sector when opening a door like vanilla Doom. This fixes the demo desync with ep1-0500.lmp.
Vanilla demos were parsing the demo type incorrectly, so altdeath demos would run in normal deathmatch. Fixed.
Display names should only target living players. Fixed.
