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)
+-------------------------
+
+* Fix new installations which broke at the step of asking for the user's desired email address, which was broken by v0.26's changes related to the control panel.
+* Fix the provisioning of TLS certificates by pinning a Python package we rely on (acme) to an earlier version because our code isn't yet compatible with its current version.
+* Reduce munin's log_level from debug to warning to prevent massive log files.
+
+v0.26 (January 18, 2018)
+------------------------
+
+Security:
+
+* HTTPS, IMAP, and POP's TLS settings have been updated to Mozilla's intermediate cipher list recommendation. Some extremely old devices that use less secure TLS ciphers may no longer be able to connect to IMAP/POP.
+* Updated web HSTS header to use longer six month duration.
+
+Mail:
+
+* Adding attachments in Roundcube broke after the last update for some users after rebooting because a temporary directory was deleted on reboot. The temporary directory is now moved from /tmp to /var so that it is persistent.
+* `X-Spam-Score` header is added to incoming mail.
+
+Control panel:
+
+* RSASHA256 is now used for DNSSEC for .lv domains.
+* Some documentation/links improvements.
+
+Installer:
+
+* We now run `apt-get autoremove` at the start of setup to clear out old packages, especially old kernels that take up a lot of space. On the first run, this step may take a long time.
+* We now fetch Z-Push from its tagged git repository, fixing an installation problem.
+* Some old PHP5 packages are removed from setup, fixing an installation bug where Apache would get installed.
+* Python 3 packages for the control panel are now installed using a virtualenv to prevent installation errors due to conflicts in the cryptography/openssl packages between OS-installed packages and pip-installed packages.
+
+v0.25 (November 15, 2017)
+-------------------------
+
+This update is a security update addressing [CVE-2017-16651, a vulnerability in Roundcube webmail that allows logged-in users to access files on the local filesystem](https://roundcube.net/news/2017/11/08/security-updates-1.3.3-1.2.7-and-1.1.10).

+
+Mail:
+
+* Updated to [Roundcube 1.3.1](https://roundcube.net/news/2017/06/26/roundcube-webmail-1.3.0-released), but unfortunately dropping the Vacation plugin because it has not been supported by its author and is not compatible with Roundcube 1.3, and updated the persistent login plugin.
+* Updated to [Z-Push 2.3.8](http://download.z-push.org/final/2.3/z-push-2.3.8.txt).
+* Dovecot now uses stronger 2048 bit DH params for better forward secrecy.
+

+
+Control Panel:
+
+* Nameserver (NS) records can now be set on custom domains.

+--------------------
+
+Mail:
+
+* The default theme for Roundcube was changed to the nicer Larry theme.
+* Exchange/ActiveSync support has been replaced with z-push 2.3.6 from z-push.org (rather than z-push-contrib).

+
+DNS:
+
+* Add support for custom CAA records.
+
+v0.22 (April 2, 2017)
+---------------------

+v0.21c (February 1, 2017)
+-------------------------
+
+Installations and upgrades started failing about 10 days ago with the error "ImportError: No module named 'packaging'" after an upstream package (Python's setuptools) was updated by its maintainers. The updated package conflicted with Ubuntu 14.04's version of another package (Python's pip). This update upgrades both packages to remove the conflict.
+
+If you already encountered the error during installation or upgrade of Mail-in-a-Box, this update may not correct the problem on your existing system. See https://discourse.mailinabox.email/t/v0-21c-release-fixes-python-package-installation-issue/1881 for help if the problem persists after upgrading to this version of Mail-in-a-Box.

+* Exchange/ActiveSync will now use your display name set in Roundcube in the From: line of outgoing email.
+
+ownCloud:
+
+* Updated ownCloud to version 9.1.1.
+
+Control panel:
+
+* Backups can now be made using rsync-over-ssh!
+* Status checks failed if the system doesn't support iptables or doesn't have ufw installed.
+* Added support for SSHFP records when sshd listens on non-standard ports.

+# Mail-in-a-Box Code of Conduct
+
+Mail-in-a-Box is an open source community project about working, as a group, to empower ourselves and others to have control over our own digital communications. Just as we hope to increase technological diversity on the Internet through decentralization, we also believe that diverse viewpoints and voices among our community members foster innovation and creative solutions to the challenges we face.
+
+We are committed to providing a safe, welcoming, and harrassment-free space for collaboration, for everyone, without regard to age, disability, economic situation, ethnicity, gender identity and expression, language fluency, level of knowledge or experience, nationality, personal appearance, race, religion, sexual identity and orientation, or any other attribute. Community comes first. This policy supersedes all other project goals.
+
+The maintainers of Mail-in-a-Box share the dual responsibility of leading by example and enforcing these policies as necessary to maintain an open and welcoming environment. All community members should be excellent to each other.
+
+## Scope
+
+This Code of Conduct applies to all places where Mail-in-a-Box community activity is ocurring, including on GitHub, in discussion forums, on Slack, on social media, and in real life. The Code of Conduct applies not only on websites/at events run by the Mail-in-a-Box community (e.g. our GitHub organization, our Slack team) but also at any other location where the Mail-in-a-Box community is present (e.g. in issues of other GitHub organizations where Mail-in-a-Box community members are discussing problems related to Mail-in-a-Box, or real-life professional conferences), or whenever a Mail-in-a-Box community member is representing Mail-in-a-Box to the public at large or acting on behalf of Mail-in-a-Box.
+
+This code does not apply to activity on a server running Mail-in-a-Box software, unless your server is hosting a service for the Mail-in-a-Box community at large.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Showing empathy towards other community members
+* Making room for new and quieter voices
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory/unwelcome comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Aggressive and micro-aggressive behavior, such as unconstructive criticism, providing corrections that do not improve the conversation (sometimes referred to as "well actually"s), repeatedly interrupting or talking over someone else, feigning surprise at someone's lack of knowledge or awareness about a topic, or subtle prejudice (for example, comments like "That's so easy my grandmother could do it.", which is prejudicial toward grandmothers).
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+* Retaliating against anyone who reports a violation of this code.
+
+We will not tolerate harassment. Harassment is any unwelcome or hostile behavior towards another person for any reason. This includes, but is not limited to, offensive verbal comments related to personal characteristics or choices, sexual images or comments, deliberate intimidation, bullying, stalking, following, harassing photography or recording, sustained disruption of discussion or events, nonconsensual publication of private comments, inappropriate physical contact, or unwelcome sexual attention. Conduct need not be intentional to be harassment.
+
+## Enforcement
+
+We will remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not consistent with this Code of Conduct. We may ban, temporarily or permanently, any contributor for violating this code, when appropriate.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project lead, [Joshua Tauberer](https://razor.occams.info/). All reports will be treated confidentially, impartially, consistently, and swiftly.
+
+Because the need for confidentiality for all parties involved in an enforcement action outweighs the goals of openness, limited information will be shared with the Mail-in-a-Box community regarding enforcement actions that have taken place.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant, version 1.4](http://contributor-covenant.org/version/1/4) and the code of conduct of [Code for DC](http://codefordc.org/resources/codeofconduct.html).

+# 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!

 * TLS certificates are generated with 2048-bit RSA keys and SHA-256 fingerprints. The box provides a self-signed certificate by default. The [setup guide](https://mailinabox.email/guide.html) explains how to verify the certificate fingerprint on first login. Users are encouraged to replace the certificate with a proper CA-signed one. ([source](setup/ssl.sh))
 * Only TLSv1, TLSv1.1 and TLSv1.2 are offered (the older SSL protocols are not offered).
-* Export-grade ciphers, the anonymous DH/ECDH algorithms (aNULL), and clear-text ciphers (eNULL) are not offered.
-* The minimum cipher key length offered is 112 bits. The maximum is 256 bits. Diffie-Hellman ciphers use a 2048-bit key for forward secrecy.
+* HTTPS, IMAP, and POP track the [Mozilla Intermediate Ciphers Recommendation](https://wiki.mozilla.org/Security/Server_Side_TLS), balancing security with supporting a wide range of mail clients. Diffie-Hellman ciphers use a 2048-bit key for forward secrecy. For more details, see the [output of SSLyze for these ports](tests/tls_results.txt).
+* SMTP (port 25) uses the Postfix medium grade ciphers and SMTP Submission (port 587) uses the Postfix high grade ciphers ([more info](http://www.postfix.org/postconf.5.html#smtpd_tls_mandatory_ciphers)).
 
 Additionally:
 
 * SMTP Submission (port 587) will not accept user credentials without STARTTLS (true also of SMTP on port 25 in case of client misconfiguration), and the submission port won't accept mail without encryption. The minimum cipher key length is 128 bits. (The box is of course configured not to be an open relay. User credentials are required to send outbound mail.) ([source](setup/mail-postfix.sh))
 * HTTPS (port 443): The HTTPS Strict Transport Security header is set. A redirect from HTTP to HTTPS is offered. The [Qualys SSL Labs test](https://www.ssllabs.com/ssltest) should report an A+ grade. ([source 1](conf/nginx-ssl.conf), [source 2](conf/nginx.conf))
 
-For more details, see the [output of SSLyze for these ports](tests/tls_results.txt).

-The cipher and protocol selection are chosen to support the following clients:
-
-* For HTTPS: Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7.
-* For other protocols: TBD.
