## Jan 20th 2020

- Allow setting DHCP reservation preference with --unattended
- Flip condition check on $dhcpReserv: first check if empty, and if not, check if it's not 1.
  Doing it the other way (first check if not 1) would give a shell error if $dhcpReserv was empty.
- Prepend 'pivpn-' to unstable repo files to limit naming conflicts
- Update variables inside unattended examples
- Remove openvpn logging setting when uninstalling the package
- Run 'apt-get update' after removing the WireGuard PPA

## Jan 8th 2020

Updates and improvements
Issue #871: fix backup script

install.sh
  installScripts function:
    update script not being copied over to /opt therefore update funcion was probably broken.
    changed script to copy all .sh scripts from .pivpn/scripts directory.

  fixed it, now works with new code refactoring,
  loads vars from setupVars
  Added backup for wireguard
  Moved script to global pivpnscripts.
  Added backup script to bash-completion
  Added backup script to pivpn script

update.sh

Updated LatestChages.md

## Jan 7th 2020

Changes for FR #897
Support For DHCP IP Reservation

Main:
  - added If statement to skipp SetStaticIPv4 if dhcpRserv=1

getStaticIPv4Settings:
  - Added Whiptail asking if user wants to use DHCP reservation Settings, this will add dhcpReserv and
    skip setStaticIPv4 while still logging everything.
ConfigExample files:
  - Added staticReserv=0 to config examples. so it can be used with Unattended install
    * 0 means static ip will be setup.
    * 1 means DHCP Reservation will be used and no chage will be made to the interfaces

- Use the wireguard script for WireGuard as well
- Updated the README in accordance to changes in the test branch

## Dec 29th 2019

* Handle running the install script over an existing installation (as the script already did before branching to test-wireguard), providing:
    - Update, downloads latest scripts from git repo
    - Repair, reinstall PiVPN while keeping existing settings
    - Reconfigure, start over overwriting the existing settings
* Tag iptables rules as an attempt to make sure that the uninstall script only removes PiVPN rules
* Change the armv6l installation to reflect the split of WireGuard snapshots into wireguard-linux-compat and wireguard-tools

## Dec 27th 2019

 - When suggesting to use Pi-hole, use the VPN server IP instead of the LAN IP to allow DNS resolution even if the user does not route the local network through the tunnel.
- Format listCONF in a similar way as listOVPN
- Specifically look for a free octet in the last word of clients.txt and not just any word.
  Necessary otherwhise public keys starting with a number will match against an octet.
  Example: if line is 'name 5abcdefgh 4', then looking for ' 5' will match but '5$' will
  not (correctly).
- 'pivpn -c' will show the Connected Clients List for WireGuard too

## Dec 10th 2019

- Use dedicated openvpn user and group for increased security
- Added basic safeguards to avoid wrecking /etc/ufw/before.rules
- Applied some Shellcheck suggested changes.
- Added safeguards to rm -rf when downloading the git repo.
- Use more variables instead of hardcoding data
- Add local resolver as DNS option

## Dec 3rd 2019

- Better client stats formatting

## Dec 2nd 2019

* Properly avoid pulling unwanted packages from unstable repo:
  - Currently apt pulls all packages from the unstable repo because the script intendation created the file 'limit-unstable' with tabs in it. Fixed using printf to create a multiline file.
- Accept debug fixes using just the enter key

## Nov 19th 2019

- Added Ubuntu Bionic support

## Nov 16th 2019

- Added back unattended installation: as expected, the user can call the install script with --unattended followed by a config file and PiVPN will be installed non-interactively.
- Removed persist-key and persist-tun from the client config.
- Reverted keepalive setting on the server to smaller values.
- See @TinCanTech's posts for the reasons of the above two: #864 (comment)
- Copied validDomain() function from the test branch.
- Removed 1024 bit certificate options, since on Buster OpenVPN does not start with such small certificates (It's related to OpenSSL 1.1.1).
- Backup /etc/openvpn and /etc/wireguard before installing.
- Always remove VPN configuration when uninstalling, but do not wipe the folder, just remove what PiVPN added.
- Fetch latest WireGuard snapshot instead of hardcoding it into the script.

## Nov 7th 2019

- Add back the uninstall script
- Only uninstall packages that were not already installed when running the PiVPN install script.
- Detect and offer to use Pi-hole
- Use checkinstall to install wireguard-tools for easy uninstallation
- Added missing dkms dependency

## Oct 19th 2019

- MakeOVPN has been updated to include the -i iOS function to allow users to create an OVPN12 format file that can be used with the iOS keychain.
- Check if -i iOS can be used (can't be used with ECDSA certificates).
- Fixed the issues with special characters in OVPN12 files.

## Oct 17th 2019

- Allow subdomain in custom DNS search list.
- Unified PiVPN configuration into the single /etc/pivpn/setupVars.conf file.
- Functions that ask the user for the port, protocol, dns, domain don't apply the setting anymore, they only save the variable on disk. Settings are applied in confOpenVPN, confOVPN, confWireGuard.
- Support and use WireGuard by default with an initial set of scripts matching current PiVPN scripts (list, create, remove clients).
- Removed OpenVPN ECDSA option.
- Renamed some variables (see pull request 849).
- Refactored several functions.

## Oct 12th 2019

* Changed pivpn command exit codes from 1 to 0
  - exit code 1 means general error hence should not be used for exiting successfully
* added backup script to backup openvpn and pivpn generated certificates
* added update script to update /opt/pivpn scripts, -t | --test | test update from test branch
* Fixed hostname length issue #831
    - the script now checks for hostname length right at the beginning and prompts for a new one.
    - HOST_NAME to host_name, as best practice variables with capitals, should be used by system variables only.
* fixed ubuntu 18.04 being detected as not supported OS, now fully supported and tested.
