v0.29 released, closes #1440

fixes #1409

This reverts commit 82844ca651 ("make certbot auto-agree to TOS if NONINTERACTIVE=1 env var is set (#1399)") and instead *always* auto-agree. If we don't auto-agree, certbot asks the user interactively, but our "curl | bash" setup line does not permit interactive prompts, so certbot failed to register and all certificate things were broken until the command was re-run interactively.

 CHANGELOG
 =========
 
+v0.29 (October 25, 2018)
+------------------------
+
+* Starting with v0.28, TLS certificate provisioning wouldn't work on new boxes until the mailinabox setup command was run a second time because of a problem with the non-interactive setup.
+* Update to Nextcloud 13.0.6.
+* Update to Roundcube 1.3.7.
+* Update to Z-Push 2.4.4.
+* Backup dates listed in the control panel now use an internationalized format.
+
+v0.28 (July 30, 2018)
+---------------------
+
+System:
+
+* We now use EFF's `certbot` to provision TLS certificates (from Let's Encrypt) instead of our home-grown ACME library.
+
+Contacts/Calendar:
+
+* Fix for Mac OS X autoconfig of the calendar.
+
+Setup:
+
+* Installing Z-Push broke because of what looks like a change or problem in their git server HTTPS certificate. That's fixed.
+
+v0.27 (June 14, 2018)
+---------------------
+
+Mail:
+
+* A report of box activity, including sent/received mail totals and logins by user, is now emailed to the box's administrator user each week.
+* Update Roundcube to version 1.3.6 and Z-Push to version 2.3.9.
+
+Control Panel:
+
+* The undocumented feature for proxying web requests to another server now sets X-Forwarded-For.
+
+v0.26c (February 13, 2018)
+--------------------------
+
+Setup:
+
+* Upgrades from v0.21c (February 1, 2017) or earlier were broken because the intermediate versions of ownCloud used in setup were no longer available from ownCloud.
+* Some download errors had no output --- there is more output on error now.
+
+Control Panel:
+
+* The background service for the control panel was not restarting on updates, leaving the old version running. This was broken in v0.26 and is now fixed.
+* Installing your own TLS/SSL certificate had been broken since v0.24 because the new version of openssl became stricter about CSR generation parameters.
+* Fixed password length help text.
+
+Contacts/Calendar:
+
+* Upgraded Nextcloud from 12.0.3 to 12.0.5.
+
 v0.26b (January 25, 2018)

+# Contributing
+
+Mail-in-a-Box is an open source project. Your contributions and pull requests are welcome.
+
+## Development
+
+To start developing Mail-in-a-Box, [clone the repository](https://github.com/mail-in-a-box/mailinabox) and familiarize yourself with the code.
+
+    $ git clone https://github.com/mail-in-a-box/mailinabox
+
+### Vagrant and VirtualBox
+
+We recommend you use [Vagrant](https://www.vagrantup.com/intro/getting-started/install.html) and [VirtualBox](https://www.virtualbox.org/wiki/Downloads) for development. Please install them first.
+
+With Vagrant set up, the following should boot up Mail-in-a-Box inside a virtual machine:
+
+    $ vagrant up --provision
+
+_If you're seeing an error message about your *IP address being listed in the Spamhaus Block List*, simply uncomment the `export SKIP_NETWORK_CHECKS=1` line in `Vagrantfile`. It's normal, you're probably using a dynamic IP address assigned by your Internet provider–they're almost all listed._
+
+### Modifying your `hosts` file
+
+After a while, Mail-in-a-Box will be available at `192.168.50.4` (unless you changed that in your `Vagrantfile`). To be able to use the web-based bits, we recommend to add a hostname to your `hosts` file:
+
+    $ echo "192.168.50.4 mailinabox.lan" | sudo tee -a /etc/hosts
+
+You should now be able to navigate to https://mailinabox.lan/admin using your browser. There should be an initial admin user with the name `me@mailinabox.lan` and the password `12345678`.
+
+### Making changes
+
+Your working copy of Mail-in-a-Box will be mounted inside your VM at `/vagrant`. Any change you make locally will appear inside your VM automatically.
+
+Running `vagrant up --provision` again will repeat the installation with your modifications.
+
+Alternatively, you can also ssh into the VM using:
+
+    $ vagrant ssh
+
+Once inside the VM, you can re-run individual parts of the setup like in this example:
+
+    vm$ cd /vagrant
+    vm$ sudo setup/owncloud.sh # replace with script you'd like to re-run
+
+### Tests
+
+Mail-in-a-Box needs more tests. If you're still looking for a way to help out, writing and contributing tests would be a great start!
