I got this from VE (they should be your homepage, damnit!) about HL version 1.0.1.6 patch:
Half-Life update 1.0.1.6 contains two new maps for Team Fortress Classic and a variety of server enhancements.
Badlands - Primarily an outdoors map with an emphasis on vertical positions, Badlands features traditional capture the flag play through a twisted collection of step canyons-a locale tailored for the sharp shooters.
Crossover - A mix of exposed outdoor areas and tight indoor spaces littered throughout the corridors of two symmetrical bases, this map provides a venue for varied and fast paced CTF games.
Server Items: We have addressed a number of server side items in this release, including the Linux message of the day fix and a number of other items requested by our Half-Life server administrators.
