= commit: 2dd7f1af27478c529e6d2d916f64daa3fbda3885
committed: Oct 28, 2016, 4:00 PM GMT+2

Added
- Stale transactions in the `backlog` table now get reassigned to another node (for inclusion in a new block): [Pull Request 359](https://github.com/planetmint/planetmint/pull/359)
- Many improvements to make the database connection more robust: [Pull Request 623](https://github.com/planetmint/planetmint/pull/623)
- The new `--dev-allow-temp-keypair` option on `planetmint start` will generate a temporary keypair if no keypair is found. The `Dockerfile` was updated to use this. [Pull Request 635](https://github.com/planetmint/planetmint/pull/635)
- The AWS deployment scripts now allow you to:
- specify the AWS security group as a configuration parameter: [Pull Request 620](https://github.com/planetmint/planetmint/pull/620)
- tell RethinkDB to bind HTTP to localhost (a more secure setup; now the default in the example config file): [Pull Request 666](https://github.com/planetmint/planetmint/pull/666)

Changed
- Integrated the new `Transaction` model. This was a **big** change; 49 files changed. [Pull Request 641](https://github.com/planetmint/planetmint/pull/641)
- Merged "common" code (used by Planetmint Server and the Python driver), which used to be in its own repository (`planetmint/planetmint-common`), into the main `planetmint/planetmint` repository (this one): [Pull Request 742](https://github.com/planetmint/planetmint/pull/742)
- Integrated the new digital asset model. This changed the data structure of a transaction and will make it easier to support divisible assets in the future. [Pull Request 680](https://github.com/planetmint/planetmint/pull/680)
- Transactions are now deleted from the `backlog` table _after_ a block containing them is written to the `bigchain` table: [Pull Request 609](https://github.com/planetmint/planetmint/pull/609)
- Changed the example AWS deployment configuration file: [Pull Request 665](https://github.com/planetmint/planetmint/pull/665)
- Support for version 0.5.0 of the `cryptoconditions` Python package. Note that this means you must now install `ffi.h` (e.g. `sudo apt-get install libffi-dev` on Ubuntu). See Pull Requests [685](https://github.com/planetmint/planetmint/pull/685) and [#698](https://github.com/planetmint/planetmint/pull/698)
- Updated some database access code: Pull Requests [676](https://github.com/planetmint/planetmint/pull/676) and [#701](https://github.com/planetmint/planetmint/pull/701)

Fixed
- Internally, when a transaction is in the `backlog` table, it carries some extra book-keeping fields:
1. an `assignment_timestamp` (i.e. the time when it was assigned to a node), which is used to determine if it has gone stale.
2. an `assignee`: the public key of the node it was assigned to.
- The `assignment_timestamp` wasn't removed before writing the transaction to a block. That was fixed in [Pull Request 627](https://github.com/planetmint/planetmint/pull/627)
- The `assignment_timestamp` and `assignee` weren't removed in the response to an HTTP API request sent to the `/api/v1/transactions/<txid>` endpoint. That was fixed in [Pull Request 646](https://github.com/planetmint/planetmint/pull/646)
- When validating a TRANSFER transaction, if any fulfillment refers to a transaction that's _not_ in a valid block, then the transaction isn't valid. This wasn't checked before but it is now. [Pull Request 629](https://github.com/planetmint/planetmint/pull/629)

Notes
- We made a small change to how we do version labeling. Going forward, we will have the version label set to 0.X.Y.dev in the master branch as we work on what will eventually be released as version 0.X.Y. The version number will only be changed to 0.X.Y just before the release. This version labeling scheme began with [Pull Request 752](https://github.com/planetmint/planetmint/pull/752)

Changed
- Set RethinkDB `read-mode='majority'` everywhere: [Pull Request 497](https://github.com/planetmint/planetmint/pull/497)

- Changed the AWS cluster deployment scripts so that the deployer now generates their keypair locally, rather than having Amazon do it: [Pull Request 567](https://github.com/planetmint/planetmint/pull/567)
- When a transaction is retrieved by `get_transaction`, a `validity` field is added with a value one of `valid`, `undecided`, or `backlog`: [Pull Request 574](https://github.com/planetmint/planetmint/pull/574)
- Renamed `current_owners` and `new_owners` (in the data models) to `owners_before` and `owners_after`, respectively (i.e. before/after *the transaction*): [Pull Request 578](https://github.com/planetmint/planetmint/pull/578)
