MMGen Wallet version 17.0.0 Stable

This version of MMGen Wallet introduces THORChain memoless swaps and XMR swaps. These features are enabled in the test suite only for now, but mainnet support can easily be switched on when they go live on the THORChain network.

Most importantly for Monero users, this version introduces transaction data integrity checking during the XMR signing process. This critical security upgrade ensures that the change address in the transaction belongs to your wallet and that the amount shown is going to the destination shown, preventing an attacker from stealing your funds in the event your online installation is ever compromised. These checks were always performed by the wallet for non-privacy coins but were regrettably overlooked for Monero. Monero users are thus urgently advised to upgrade both online and offline installations.

The release also includes some minor bugfixes, a new transaction versioning system, more secure handling of legacy transaction files, and lots of code cleanups suggested by static analyzers, so an upgrade will benefit all users.

As an afterword to the Monero security fix, it must be mentioned that no system, however secure, can do everything for the user. When sending funds to an outside address, for example, the offline installation has no way of knowing whether the destination and amount are what the user intended. A good rule of thumb is to always check the offline signing summary to ensure that the transaction type is correct and, for transfers, that the address and amount are correct. This advice applies to all coins, by the way, not just Monero.

Important new features:

For details, see the XMR section of the Altcoin-and-Forkcoin-Support wiki page.

Major new feature:
- XMR compatibility mode (d8439ba6, 4a4b8149, e69dfbe8, 907bdc2b, 7b53f433, cb99e13c, 1132d0ff, bdd7dd33)

- mmgen-txsend: support transaction selection with --status (4f1b16f4)
- BTC: increase maximum OP_RETURN data size to 4096 bytes (81ece1ff)
Security, bugfix, cleanup:
- aiohttp: restore use as context manager, remove version pin (a3e7c08f)
- txbump: display outputs in correct (raw) order (e3799260)
- decodeScriptPubKey(): parse nulldata correctly (4b55f115)
- use hashlib for keccak-256 function on newer systems; eliminate dependency on pycryptodome package (20734cc7)

MMGen Wallet Version 14.0.0 Release Notes

This special release marks the MMGen Project’s 10th anniversary on Github.

Though only one new noteworthy feature has appeared in MMGen Wallet since v13.3.0, users can benefit from numerous bugfixes, code cleanups, and installation and testing improvements, along with updated coin daemon support. Upgrading is therefore highly recommended:
```
$ pip3 install --upgrade mmgen-wallet
