On January 22, the Indiana Senate Elections Committee passed SB 328 by 6-3. It lowers the number of signatures for an independent candidate, or the nominee of an unqualified party, from 2% of the last Secretary of State vote, to one-half of 1% of the last Secretary of State vote. If it passes, it takes effect January 1, 2019. Thanks to Craig Marolf for this news.
UPDATE: see this news story about the bill (the lower half of the article).
