@@ -1,3 +1,19 @@
- 0.4.2
* Correct burn interface implementation
- 0.4.1
* Eliminate solidity compiler warnings
- 0.4.0
* Rename taxLevel to decayLevel in contract
* Add sweep contract method to fully empty one account into another
- 0.3.6
* Reinstate owner as minter by default
- 0.3.0
* Smart contracts use abdk math libraries, all exponential operations are static gas cost
* Add expiry features, after which balances are frozen and no more transfers or demurrage will occur
* Add sealable features for supply, sink address, expiry and minters (when sealed cannot be changed)
* Deployer script now takes demurrage amount as ppm instead of literal growth fraction
* Retire old multi and cap contracts
* Replace contract bitfields for redistributions with structs
- 0.2.0
* Add token burn function
* Fix gas leak when calculating decay on period change
