We have released a Beta update for Half-Life Deathmatch: Source. Changes in this update are:

• Fixed incorrect default maxplayers being set
• Fixed singleplayer UI being used in the Options and Loading dialog
• Fixed death notices being truncated when using 5:4 aspect ratios
• Added mounting of Half-Life: Source content if present, set the cl_load_hl1_content convar to enable this feature
