[himorin]

from item 4. in #99 (comment)
There are several tables in Appendix A for classes of characters, we had border in 2nd ed. but not for now.

@r12a This reminds me of need for a pre-release testing. Is there a standard process, or how is it usually done?

[himorin]

closing per #132 merged.
@kidayasuo shall I file new issue for pre-release testing, or continue email conversation?

[kidayasuo]

Yes, please file a new issue. As this revision got structural changes in addition to relatively simple errata fixes, I believe we need more testing.
What are standard practices? also I wonder how it was done on the first version.
