2.0.4
2.0.4 was a minor update for Team Fortress 2 Classic, released on December 5, 2022. It primarily featured bugfixes, as well as some map changes, including the addition of Pelican Peak. It was also the first patch to be released alongside the "TF2CDownloader" updating utility. The patch notes were released on the official blog. Seven days later, the official TF2 Classic YouTube channel posted an announcement video outlining the fixes before releasing an upcoming major update.
This update came after 2.0.3 and before 2.1.0.

Maps with a large or detailed lightmap no longer sometimes crash the game with an "Engine Hunk Overflow" error
Fix a common crash in Halloween maps caused by not having enough spawn points for the requested entity amount in entity_spawn_manager
Victory reasons will no longer sporadically be missing
General changes
Added crash reporting through Sentry. This is opt-in, and on launching the game for the first time, you will be asked for consent to enable automatic sending. Reports will be used to identify and fix common crashes. Details on collected info are included in a GDPR.txt file shipped with the game, or at https://tf2classic.com/privacy
TF2 Classic will now pop up a window if it crashes, informing you of the crash, instead of hard crashing to desktop

Added "flush_dls", "flush_sprays", and "flush_map_overrides", new commands which can all manually delete various files you've downloaded from remote servers
Item schemas are now removed when disconnecting from a server, preventing servers from overriding your item list on other servers
object_deflected events are now properly sent
Burning death animations can now be toggled with tf2c_burning_deathanim
Grenades no longer sometimes bounce off of enemy buildings without exploding

Properly fixed being able to place buildings through seams in maps

Healing indicators will no longer appear over invisible enemy players
The mod_ammo_per_shot attribute now consumes the right amount of ammo on weapons without a clip
The headshot sound effect is no longer predicted by the client, avoiding the issue where you hear the sound but the headshot isn't registered by the server
Sniper dots now properly match where the client is looking, and update more quickly - thank you to Shounic for pointing this out in his video here
The move speed increase from tf2c_gun_mettle_spy now only affects Spy, rather than all classes
The VIP is no longer allowed to use the extendfreeze command
Hitsounds, killsounds, fast weapon switch, and combat text batching are now enabled by default for new installations

When a vote is started, the calling playerproperly is logged in the console
The option for toggling game audio while the window is in the background now works properly

Added "sv_quota_stringcmdspersecond" to limit the amount of string commands that clients are allowed to send to the server per second before getting kicked - this should fix so called "lagbots"
Fixed exploits involving roll in user commands - thank you to Pelipoika
Added "net_chan_proctime_limit_ms" to limit the amount of time, in milliseconds, that clients are allowed to make the server spend processing their packets before getting kicked - this should also fix so called "lagbots"
