+
+Note that v0.42 (July 4, 2019) was pulled shortly after it was released to fix a Nextcloud upgrade issue.
+
+v0.41 (February 26, 2019)
+-------------------------
+
+System:
+
+* Missing brute force login attack prevention (fail2ban) filters which stopped working on Ubuntu 18.04 were added back.

+* Incoming messages addressed to more than one local user were rejected because of a bug in spampd packaged by Ubuntu 18.04. A workaround was added.
+
+Contacts/Calendar:
+
+* Upgraded Nextcloud from 13.0.6 to 14.0.6.
+* Upgraded Contacts from 2.1.5 to 2.1.8.
+* Upgraded Calendar from 1.6.1 to 1.6.4.
+
+v0.40 (January 12, 2019)
+------------------------
+
+This is the first release for Ubuntu 18.04. This version and versions going forward can **only** be installed on Ubuntu 18.04; however, upgrades of existing Ubuntu 14.04 boxes to the latest version supporting Ubuntu 14.04 (v0.30) continue to work as normal.
+
+When **upgrading**, you **must first upgrade your existing Ubuntu 14.04 Mail-in-a-Box box** to the latest release supporting Ubuntu 14.04 --- that's v0.30 --- before you migrate to Ubuntu 18.04. If you are running an older version of Mail-in-a-Box which has an old version of ownCloud or Nextcloud, you will *not* be able to upgrade your data because older versions of ownCloud and Nextcloud that are required to perform the upgrade *cannot* be run on Ubuntu 18.04. To upgrade from Ubuntu 14.04 to Ubuntu 18.04, you **must create a fresh Ubuntu 18.04 machine** before installing this version. In-place upgrades of servers are not supported. Since Ubuntu's support for Ubuntu 14.04 has almost ended, everyone is encouraged to create a new Ubuntu 18.04 machine and migrate to it.
+
+For complete upgrade instructions, see:
+
+https://discourse.mailinabox.email/t/mail-in-a-box-version-v0-40-and-moving-to-ubuntu-18-04/4289
+
+The changelog for this release follows.
+
+Setup:
+
+* Mail-in-a-Box now targets Ubuntu 18.04 LTS, which will have support from Ubuntu through 2022.
+* Some of the system packages updated in virtue of using Ubuntu 18.04 include postfix (2.11=>3.3) nsd (4.0=>4.1), nginx (1.4=>1.14), PHP (7.0=>7.2), Python (3.4=>3.6), fail2ban (0.8=>0.10), Duplicity (0.6=>0.7).
+* [Unofficial Bash Strict Mode](http://redsymbol.net/articles/unofficial-bash-strict-mode/) is turned on for setup, which might catch previously uncaught issues during setup.
+
+Mail:
+
+* IMAP server-side full text search is no longer supported because we were using a custom-built `dovecot-lucene` package that we are no longer maintaining.
+* Sending email is now disabled on port 25 --- you must log in to port 587 to send email, per the long-standing mail instructions.
+* Greylisting may delay more emails from new senders. We were using a custom-built postgrey package previously that whitelisted sending domains in dnswl.org, but we are no longer maintaining that package.
+
+v0.30 (January 9, 2019)
+-----------------------
+
+Setup:
+
+* Update to Roundcube 1.3.8 and the CardDAV plugin to 3.0.3.
+* Add missing rsyslog package to install line since some OS images don't have it installed by default.
+* A log file for nsd was added.
+
+Control Panel:
+
+* The users page now documents that passwords should only have ASCII characters to prevent character encoding mismaches between clients and the server.
+* The users page no longer shows user mailbox sizes because this was extremely slow for very large mailboxes.
+* The Mail-in-a-Box version is now shown in the system status checks even when the new-version check is disabled.
+* The alises page now warns that alises should not be used to forward mail off of the box. Mail filters within Roundcube are better for that.
+* The explanation of greylisting has been improved.
+
+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:
+
+* Update to Roundcube 1.3.3.
+
+Control Panel:
+
+* Allow custom DNS records to be set for DNS wildcard subdomains (i.e. `*`).
+
+v0.24 (October 3, 2017)
+-----------------------
+
+System:
+
+* Install PHP7 via a PPA. Switch to the on-demand process manager.
+
+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.
+
+Nextcloud:
+
+* Nextcloud updated to 12.0.3, using PHP7.
+
+Control Panel:
+
+* Nameserver (NS) records can now be set on custom domains.
+* Fix an erroneous status check error due to IPv6 address formatting.
+* Aliases for administrative addresses can now be set to send mail to +tag administrative addresses.
+
+v0.23a (May 31, 2017)
+---------------------
+
+Corrects a problem in the new way third-party assets are downloaded during setup for the control panel, since v0.23.
+
+v0.23 (May 30, 2017)
+--------------------
+
+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).
+
+ownCloud (now Nextcloud):
+
+* ownCloud is replaced with Nextcloud 10.0.5.
+* Fixed an error in Owncloud/Nextcloud setup not updating domain when changing hostname.
+
+Control Panel/Management:
+
+* Fix an error in the control panel showing rsync backup status.
+* Fix an error in the control panel related to IPv6 addresses.
+* TLS certificates for internationalized domain names can now be provisioned from Let's Encrypt automatically.
+* Third-party assets used in the control panel (jQuery/Bootstrap) are now downloaded during setup and served from the box rather than from a CDN.
+
+DNS:
+
+* Add support for custom CAA records.

+# 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!

-ppa instructions
-================
-
-Mail-in-a-Box maintains a Launchpad.net PPA ([Mail-in-a-Box PPA](https://launchpad.net/~mail-in-a-box/+archive/ubuntu/ppa)) for additional deb's that we want to have installed on systems.
-
-Packages
---------
-
-* postgrey, a fork of [postgrey](http://postgrey.schweikert.ch/) based on the [latest Debian package](http://git.debian.org/?p=collab-maint/postgrey.git), with a modification to whitelist senders that are whitelisted by [dnswl.org](https://www.dnswl.org/) (i.e. don't greylist mail from known good senders).
-
-* dovecot-lucene, [dovecot's lucene full text search plugin](http://wiki2.dovecot.org/Plugins/FTS/Lucene), which isn't built by Ubuntu's dovecot package maintainer unfortunately.
-
-Building
---------
-
-To rebuild the packages in the PPA, you'll need to be @JoshData.
-
-First:
-
-* You should have an account on Launchpad.net.
-* Your account should have your GPG key set (to the fingerprint of a GPG key on your system matching the identity at the top of the debian/changelog files).
-* You should have write permission to the PPA.
-
-To build:
-
-	# Start a clean VM.
-	vagrant up
-
-	# Put your signing keys (on the host machine) into the VM (so it can sign the debs).
-	gpg --export-secret-keys | vagrant ssh -- gpg --import
-
-	# Build & upload to launchpad.
-	vagrant ssh -- "cd /vagrant && make"
-
-Mail-in-a-Box adds our PPA during setup, but if you need to do that yourself for testing:
-
-	apt-add-repository ppa:mail-in-a-box/ppa
-	apt-get update
-	apt-get install postgrey dovecot-lucene
-

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).
 
 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.

In enterprise environments where the box may host the mail of untrusted users, it is important to guard against users impersonating other users.
 
 The box restricts the envelope sender address (also called the return path or MAIL FROM address --- this is different from the "From:" header) that users may put into outbound mail. The envelope sender address must be either their own email address (their SMTP login username) or any alias that they are listed as a permitted sender of. (There is currently no restriction on the contents of the "From:" header.)

-# Install a local DNS server, rather than using the DNS server provided by the
-# ISP's network configuration.
+# Install a local recursive DNS server --- i.e. for DNS queries made by
+# local services running on this machine.
 #
-# We do this to ensure that DNS queries
-# that *we* make (i.e. looking up other external domains) perform DNSSEC checks.
-# We could use Google's Public DNS, but we don't want to create a dependency on
-# Google per our goals of decentralization. `bind9`, as packaged for Ubuntu, has
-# DNSSEC enabled by default via "dnssec-validation auto".
+# (This is unrelated to the box's public, non-recursive DNS server that
+# answers remote queries about domain names hosted on this box. For that
+# see dns.sh.)
 #
-# So we'll be running `bind9` bound to 127.0.0.1 for locally-issued DNS queries
-# and `nsd` bound to the public ethernet interface for remote DNS queries asking
-# about our domain names. `nsd` is configured later.
+# The default systemd-resolved service provides local DNS name resolution. By default it
+# is a recursive stub nameserver, which means it simply relays requests to an
+# external nameserver, usually provided by your ISP or configured in /etc/systemd/resolved.conf.
+#
+# This won't work for us for three reasons.
+#
+# 1) We have higher security goals --- we want DNSSEC to be enforced on all
+#    DNS queries (some upstream DNS servers do, some don't).
+# 2) We will configure postfix to use DANE, which uses DNSSEC to find TLS
+#    certificates for remote servers. DNSSEC validation *must* be performed
+#    locally because we can't trust an unencrypted connection to an external
+#    DNS server.
+# 3) DNS-based mail server blacklists (RBLs) typically block large ISP
+#    DNS servers because they only provide free data to small users. Since
+#    we use RBLs to block incoming mail from blacklisted IP addresses,
+#    we have to run our own DNS server. See #1424.
+#
+# systemd-resolved has a setting to perform local DNSSEC validation on all
+# requests (in /etc/systemd/resolved.conf, set DNSSEC=yes), but because it's
+# a stub server the main part of a request still goes through an upstream
+# DNS server, which won't work for RBLs. So we really need a local recursive
+# nameserver.
+#
+# We'll install `bind9`, which as packaged for Ubuntu, has DNSSEC enabled by default via "dnssec-validation auto".
+# We'll have it be bound to 127.0.0.1 so that it does not interfere with
+# the public, recursive nameserver `nsd` bound to the public ethernet interfaces.
 #
 # About the settings:
 #
-# * RESOLVCONF=yes will have `bind9` take over /etc/resolv.conf to tell
-#   local services that DNS queries are handled on localhost.
 # * Adding -4 to OPTIONS will have `bind9` not listen on IPv6 addresses
 #   so that we're sure there's no conflict with nsd, our public domain
 #   name server, on IPV6.
 # * The listen-on directive in named.conf.options restricts `bind9` to
 #   binding to the loopback interface instead of all interfaces.

 # The server_names_hash_bucket_size seems to prevent long domain names!
 # The default, according to nginx's docs, depends on "the size of the
 # processor’s cache line." It could be as low as 32. We fixed it at
 # 64 in 2014 to accommodate a long domain name (20 characters?). But
 # even at 64, a 58-character domain name won't work (#93), so now
 # we're going up to 128.
+#
+# Drop TLSv1.0, TLSv1.1, following the Mozilla "Intermediate" recommendations
+# at https://ssl-config.mozilla.org/#server=nginx&server-version=1.17.0&config=intermediate&openssl-version=1.1.1.
