Another week of great pull requests to our open source projects.

## kumade

A _new gem_, started by Gabe Berke-Williams
([gabebw](https://github.com/gabebw)) with much help from Nick Quaranto
([qrush](https://github.com/qrush)), kumade is a drop-in Heroku deployer that
handles assets, migrations, and sanity checks. It's under heavy development so
stay tuned to hear more, or [try it out
yourself](https://github.com/thoughtbot/kumade).

The name comes from the Japanese word for "bamboo rake" and is pronounced "koo-mah-day".

## appraisal

Appraisal is our gem for testing engines against multiple versions of
Rails—or really, for testing any gem against multiple gemsets. We use it
to make sure our gems continue to work against various version of Rails.

Matt Griffin ([betamatt](https://github.com/betamatt)) noticed that the
excellent Aruba gem is listed as a runtime dependency even though it is most
definitely a development dependency, and fixed that
([276cc9b](https://github.com/thoughtbot/appraisal/commit/276cc9b6e756230f0734d999ced3a1217fdec2f6
"Aruba should not be a runtime dependency")).

## clearance

Clearance, our authentication engine, got a little formatting fix for the README
([77bb97a](https://github.com/thoughtbot/clearance/commit/77bb97ae77c3dc8df53df8ed0d124dc36cc4e8e5
"Escape underscore in ")) thanks to Quico Moya
([qmoya](https://github.com/qmoya)).

## factory_bot[^1]

Our popular fixture-improving testing gem, factory_bot, got more specs for
assigning associations
([841e012](https://github.com/thoughtbot/factory_bot/commit/841e012c5dffa415571f85f11ca53197d49dd695
"Add acceptance spec covering assigning associations via :factory")) from Josh
Clayton ([joshuaclayton](https://github.com/joshuaclayton)) and a hard decision
that non-block values are evaluated before block values
([28f541e](https://github.com/thoughtbot/factory_bot/commit/28f541eefc840a0943a9cbb8f057e4f5ce0476af
"Ensure static attributes are executed before dynamic ones.")) thanks to Flavio
Castelli ([flavio](https://github.com/flavio)).

Since we love pushing new versions while I'm writing this, Josh then pushed
_version 2.0.3 of factory_bot_
([ec88698](https://github.com/thoughtbot/factory_bot/commit/ec886985d114156e517de3f9b1e31a7e63895acf
"Bump version to 2.0.3 ")).

## capybara-webkit

Our headless webkit-based integration testing tool, capybara-webkit, saw a bunch
of documentation and session love this week.

Dennis Prochniak ([denysonique](https://github.com/denysonique)) and Diego
Plentz ([plentz](https://github.com/plentz)) clarified documentation for Gentoo
([9b53e01](https://github.com/thoughtbot/capybara-webkit/commit/9b53e0141d3d83b06bb29d28626b0568909d1867
"Gentoo Linux qt-webkit install instruction") and
[8850f2d](https://github.com/thoughtbot/capybara-webkit/commit/8850f2db4536570d6e706efdc2a1b69be5c2f846
"Edited README.md via GitHub")) and OS X Lion
([47b8c86](https://github.com/thoughtbot/capybara-webkit/commit/47b8c868967b492fe7c1ed6ec602187b0bc64efc
"splitting OS X instructions in Lion and pre-Lion.")), respectively.

Then our Matt Mongeau ([halogenandtoast](https://github.com/halogenandtoast))
got it passing capybara's session spec and session spec with JavaScript
([c621e65](https://github.com/thoughtbot/capybara-webkit/commit/c621e651c9ba45bb4be06f32677321fc74b49175
"Support Textareas#value"),
[983b556](https://github.com/thoughtbot/capybara-webkit/commit/983b556fa83c10a4de903bee56dd53ba5075eb27
"Support maxlength"),
[63e5a53](https://github.com/thoughtbot/capybara-webkit/commit/63e5a53c014ac2e35582f032c5fea7f01dd96583
"implement node#selected?"),
[5d50d77](https://github.com/thoughtbot/capybara-webkit/commit/5d50d77b3c6cd76e8d6f41a2aa253380f2eb299c
"Fix unselect"),
[4642d33](https://github.com/thoughtbot/capybara-webkit/commit/4642d338cc927bf71b86bac8cbc250fefb38d71d
"Session spec is working"), and
[81ad8fd](https://github.com/thoughtbot/capybara-webkit/commit/81ad8fd130437149d843191893550160cd6ec6c3
"Implement source and body. Evaluate javascript should return nil when empty")).
This means that the session object works exactly like any other capybara session
object.

## paperclip

Our file uploading gem, paperclip, got some love this week: Reinaldo de Souza
Junior ([juniorz](https://github.com/juniorz)) localized error messages by
default
([6fd2cf7](https://github.com/thoughtbot/paperclip/commit/6fd2cf7e93584b2ae905d495c31b2d28b774d466
"Makes the error message localized by default.")) while Matthew Schulkind
([mschulkind](https://github.com/mschulkind)) generalized the filename extension
then made it generate the correct one based on the content type
([fdbd7bf](https://github.com/thoughtbot/paperclip/commit/fdbd7bfa1033cf597d3d23432827d57f457f8e48
"Add a :content_type_extension interpolation to derive a file extension from the
content type.")).  ## paul_revere

We saw some bundler- and gem-related upgrades to paul_revere, the gem to add
quick announcements to Rails apps, thanks to Christopher Meiklejohn
([cmeiklejohn](https://github.com/cmeiklejohn))
([7d5eebc](https://github.com/thoughtbot/paul_revere/commit/7d5eebc85fbd689632ba59adc2e985513bc35635
"Allow rails 3.1 testing, remove explicit dep on redgreen."),

[3039333](https://github.com/thoughtbot/paul_revere/commit/30393336efcbec75a3a556ca3fde30076fbda4d6
"Don"), and
[e217b85](https://github.com/thoughtbot/paul_revere/commit/e217b855661dd53bb4c04d8748f421c69ceab265
"Use the .up syntax, instead of migrate(:up) since that")).

## bourbon

Phil LaPier ([plapier](https://github.com/plapier)) continues on with bourbon,
cleaning up the README
([02900ae](https://github.com/thoughtbot/bourbon/commit/02900ae001eeb106d5d6512bb2824be8660bf9d8
"cleaned up button readme")) and fixing a bug in `linear-gradient`

"Fix linear-gradient css3 bug with background positioning")). He then pulled in
a documentation fix from Andrés Mejía ([andmej](https://github.com/andmej)) to
include `box-shadow` in the full list of mixins
([78cf621](https://github.com/thoughtbot/bourbon/commit/78cf621f1c679168b37c2374de4dd1be0c15fe13
"Adding box-shadow to full list.")) before releasing _version 0.1.3 of bourbon_
([09a875f](https://github.com/thoughtbot/bourbon/commit/09a875f7ae79af4b561368813520c3f1d79caef6
"Version bump to 0.1.3")).

[Travis CI](http://travis-ci.org/) for our open source projects. He added it to
