Why do you need to double or halve the range?

comment How do i get info from Bitcoin QT 0.7 to Bitcoin QT 0.11?
No need for incremental updates. Bitcoin Core's wallet files are backward compatible down to very early versions (0.3.x at least if not older), ignoring potential BDB version compatibilities (which can be bypassed using external bdb conversion tools).

@kym That looks like an error from 0.7, as blkindex is no longer used since 0.8. What happens if you just start the new version?

If you don't use settxfee, Bitcoin Core will use the results of automatic fee estimation.

comment To what end do miners typically put "nonstandard" transactions
The type of transaction you're seeing is not really non-standard; they're just not being accepted due to being nonfinal, which means they have locktime that's set in the future.

comment To what end do miners typically put "nonstandard" transactions
That message means that you're seeing a transaction on the network being relayed which is not yet valid in a block. They are nonstandard because we don't want them to fill up the mempool awaiting acceptance into a block. These are not transactions in blocks, they are not produced by miners. The most common cause is that your node is a bit behind in synchronization, so it's mistaken about what is acceptable. This corrects itself when it's synchronized.

comment SegWit and SPV-mining. What if...?
0.9.x won't create blocks with segwit transactions, but yes, it will accept, so your point (2) is correct. However, mining such an invalid block will only happen intentionally, and is costly. Furthermore, because the rule only activates after 95% support, a chain not building on top will grow 20x faster, so confirmations on top are very unlikely.
