[Changelog] Piston 0.3.1

Pist has now been release in version 0.3.1. Quite some changes have been made that improve the use of piston as a command line tool and as a library.

New:

• [piston] Support for UTF-8 bodies

  Piston now supports UTF8 encoded bodies (e.g. text). Note that
  permlink does not yet Support UTF-8 such that either

  • the title should be latin encoded, or
  • a latin encoded permlink needs to be provided manually

• [piston, steem] Allow to decrypt memos and show them in the history

  This call works like this:

  piston history --types transfer --memos <account>
  

  You will be asked to provide the passphrase for your wallet to obtain
  the memo private key (which needs to be added to piston)

• [piston, steem] add call for convertion of SBD

  This method allows to convert SteemDollar to STEEM using the internal convertion
  rate after 1 week. Note, that when you convert, you will obtain the
  corresponding amount of STEEM only after waiting 1 week. ::

  piston convert --account <account>
  

• [piston] show account permissions

  Any account permission can be inspected using::

  piston permissions [<account>]
  

  The take the following form::

  +------------+-----------+-----------------------------------------------------------+
  | Permission | Threshold |                                               Key/Account |
  +------------+-----------+-----------------------------------------------------------+
  |      owner |         2 |                                                fabian (1) |
  |            |           | STM7mgtsF5XPU9tokFpEz2zN9sQ89oAcRfcaSkZLsiqfWMtRDNKkc (1) |
  +------------+-----------+-----------------------------------------------------------+
  |     active |         1 | STM6quoHiVnmiDEXyz4fAsrNd28G6q7qBCitWbZGo4pTfQn8SwkzD (1) |
  +------------+-----------+-----------------------------------------------------------+
  |    posting |         1 |                                             streemian (1) |
  |            |           | STM6xpuUdyoRkRJ1GQmrHeNiVC3KGadjrBayo25HaTyBxBCQNwG3j (1) |
  |            |           | STM8aJtoKdTsrRrWg3PB9XsbsCgZbVeDhQS3VUM1jkcXfVSjbv4T8 (1) |
  +------------+-----------+-----------------------------------------------------------+
  

  The permissions are either owner (full control over the account),
  active (full control, except for changing the owner), and
  posting (for posting and voting). The keys can either be a public
  key or another account name while the number behind shows the weight of
  the entry. If the weight is smaller than the threshold, a single
  signature will not suffice to validate a transaction

• [piston,steem] allow, disallow access to your account by other accounts (#54)

  Permissions can be changed using:::

  piston allow --account <account> --weight 1 <foreign_account>
  piston disallow --permission <foreign_account>
  

  More details and the default parameters can be found via:::

  piston allow --help
  piston disallow --help
  

• [piston] allow --tags when 'post'ing using the cli

  You can use this feature like this:

  piston post --file "post.md" --author xeroc --permlink "my-title" --category spam --title "My Title" --tags tag1 tag2 tag3

• [wallet] allow more advanced key overwrite possibilities for Piston/Steem/Wallet

  Three wallet operation modes are possible:

  • Wallet Database: Here, piston loads the keys from the locally stored wallet SQLite database (see storage.py). To use this mode, simply call Steem() without the keys parameter
  • Providing Keys: Here, you can provide the keys for your accounts manually. All you need to do is add the wif keys for the accounts you want to use as a simple array using the keys parameter to Steem().
  • Force keys: This more is for advanced users and requires that you know what you are doing. Here, the keys parameter is a dictionary that overwrite the active, owner, posting or memo keys for any account. This mode is only used for foreign signatures!

• [wallet] no longer support empty passphrases, use UNLOCK environmental variable instead #53

  This can be used like this:

  UNLOCK="sup3rs3cre7" piston post
  

Fixes:

• [Makefile] Add Tags to changelog post
• [docs] Added more subcommands to the docs
• [fix] Why were owner and posting keys mixed up?
• [fix] addPrivateKey to detect type properly
• [makefile] No more editing of old posts

• [piston,steem] do not allow voting on archived posts (waste of throughput)
• [piston] Add --nowallet call to prevent piston from loading/creating a new wallet
• [piston] allow @-prefix when setting variable #44
• [piston] delkey requires confirmation
• [piston] more easily readable interest payment date
• [robustness] don't fail if things go wrong on total_payout_value
• [setup] remove steem/graphene from additional requirements
• [steem,piston] move account_history into python-steem and correct parameter name
• [steem] allow to provide multiple tags instead of just a category
• [steem] clarify _connect() only for internal use #47
• [steem] ensure debug and nobroadcast from parameters
• [steem] fix #41
• [steem] fix loop_account_history and define rational defaults
• [steem] move WebSteem to piston.steem.SteemConnector
