Well, this turned out to be a larger revision than I had intended. The complete list of changes is at ftp://hyper.stanford.edu/pub/pcmcia/CHANGES.
Toshiba appears to be setting itself up as the new Bad Boy for Linux PCMCIA support, thanks to an inability to release specs for the ToPIC chip sets. Until specs are available, there will be no support for 32-bit cards on Toshiba platforms, and 16-bit support may be flaky.
The PCMCIA-HOWTO has been changing quickly: I'm expanding the section on troubleshooting common problems, and would like to fill out the section on PCMCIA specifics for common Linux distributions. I would appreciate help with this section, since I can't follow all distributions myself.
CardBus support is still undergoing fairly rapid change. The 3c575 driver is now bundled with the main package, and an experimental driver for the Adaptec 1480 is also included. Due to changes in PCI support, CardBus cannot be made to work with recent (post 2.1.90) kernels. Hopefully, the necessary hooks for supporting removable PCI devices will appear in the near future. Once that is available, I think this will also solve some problems people have been having with the Adaptec card.
