I've finally released the third alpha of my climb plugin. You can get it from the amxx forums by either clicking the updated link in the upper right, or using the following link:

v2.0a3 (JUNE 21, 2007)
+: New alias for restart, /start.
+: HP set to 512 when finished as god mode replacement. God mode prevents people from seeign each others names.
+: Replicate hud messages and timer to spectators.
+: Replacement flashlight/nightvision. Change color with cvars climb_light_r, ..._g, ..._b
+: Cvar climb_start_respawn: eliminates unnecessary respawning, admin can enable if needed
+: Cvar climb_water_nodraw: Makes func_water entities invisible to help with players FPS issues(off by default).
+: Fake client added to CT team to prevent round end. Automatically leaves when the server is almost full, and rejoins as it empties.
+: Two new commands, /scout and /usp, to get a scout or usp if you need one, or more ammo.
+: New command /ungocheck or /ungc. Takes you to where you were before you last used gocheck.
+: Can use chooseteam button or kill command to switch between spectating and playing.
+: Plugin automatically disables on map change. Automatically enables if it finds a start button in new map. Setting the cvar climb to 1 in a map config will force the plugin to run.
c: Spectators stay listed as CT on CS scoreboard so their rank will always show.
c: Command amx_goto can be used by any player once they've completed the map.
c: Players don't spawn with scout or c4 anymore.
c: Newer unsolid render is default.
c: New unsolid code provides perfect touch detection and eliminates problems that occurred in some maps.
c: Decreased the wait time on some of the command timeouts.
c: Replicated button use code from HL SDK. Start and finish button use detection is now perfect.
c: In maps with built in healing climb auto heal is disabled(some maps like this have falling areas where you're not supposed to heal).
f: Lag caused by respawning is pretty much eliminated by new weapon cleanup code and not giving as many weapons on spawn.
f: MySQL query format problem for auto increment fields.
f: SQLite query problem. Replaced single quotes around strings with double quotes.
f: HLTV proxies caused two adjacent rows in scoreboard to be same color.
f: Spectator lag bug.
f: Bug where players had 511 HP on every map.
