# Arti 0.1.0 — 1 Mar 2022

blurb blurb

(I've caught up, as to be288399ec809c46905b9f02599fa9df66968f51)

This release marks the completion of our 0.1.0 milestone.  With this

milestone, we now consider Arti ready for experimental embedding within

other applications.

Arti 0.1.0 marks another important step towards stability, and the

completion of our 0.1.0 milestone.  With this milestone, we now consider

Arti ready for experimental embedding within other applications.

Additionally with this release, we're now ready to declare the

`arti_client` API more or less stable and supported.  (We're not

  ([!262], [!291], [!325], [#322], [#348])

- The interface to construct a `TorClient` instance has been completely

  replaced.  The new API should be stable, and prevent the need for

  additional breaking changes in the future. ([#350], [!364])

  additional breaking changes in the future. ([#350], [!364], [#326])

- Many smaller changes, too numerous to list.  (Starting _after_ this

  release, we will try be much more careful about breaking changes, and

  note them specifically here.)

  observe its bootstrapping progress and/or bootstrap it

  at a later time.  ([#293], [!298])

- You can configure an unbootstrapped TorClient object to automatically

  bootstrap itself the first time it's used. ([!322)

  bootstrap itself the first time it's used. ([!322])

- Arti now returns a webpage with an error message if you try to use its

  SOCKS proxy as an HTTP proxy ([!348])

- We now an [arti-hyper] crate for using Arti with the [hyper] HTTP

  library.  This is also good example code for showing how to integrate Arti

  with other tools. ([!342], [!355]]

### Major bugfixes

  could result in cell reordering, leading to relays closing our circuits

  because of protocol violations. ([!264], [!282])

- Fixed bugs that could cause strange behavior on shutdown or failure

  during circuit construction. ([#210], [#365], [!363], [!366])

  during circuit construction. ([#210], [#365], [!363], [!366], [!368])

### Infrastructure

  object. ([#278], [!322])

- Provide an example for how to [override the default TCP-connect]

  implementation. ([!341], [!356])

- We now provide an example of how to use Arti with the [hyper] HTTP

  library.  This takes the form of a usable [`arti-hyper`] crate.

- 

### Cleanups, minor features, and minor bugfixes

- The `arti` proxy now starts listening on its SOCKS port immediately,

  rather than waiting for bootstrapping to complete. ([!333])
