Re: [Tools-discuss] question on datatracker access to particular I-D version

[Brian E Carpenter <[e-mail]>]

It seems to me that there's a bug.

Go to https://datatracker.ietf.org/doc/draft-hansen-rfc-use-of-pdf/02/

The links for html and pdf formats bring up the -02 version, as expected.
The link for txt format brings up the latest version.
