Changing the fees required for transactions to be relayed across the network and/or accepted by miners into their blocks requires care; policy mis-matches can result in users' transactions never confirming, either because they never reach a miner (they are not relayed) or because they are rejected by miners.
I have been working on simplifying the transaction fee rules for the 0.9 release; this document is intended to capture all of the details needed to make that transition as smoothly as possible.
The general idea is to make sure the transaction-generating code (the wallet code) is conservative, and generates transactions compatible with the previous version's rules. The relay and mining code is changed more aggressively, to anticipate future releases.
