v3.10.4 - Empty connection fix for NordVPN and Windscribe

Fix: Empty connections for NordVPN and Windscribe

v3.12.1: Revert to Alpine 3.12 for 32 bit systems

Revert back to Alpine 3.12 and Openvpn 2.4.10-r0 to fix Openvpn TLS issues with time due to the Alpine 3.13 upgrade.

v3.12.0 Upgrade to Alpine 3.13 and Openvpn ping fixes

Features

• Upgrade Alpine to 3.13
• Set a 10s ping with a 60s exit ping for all openvpn configurations, so that openvpn exits and restarts if it does not receive a ping for 60s
• Openvpn exits if it encounters a TLS issue. It will then be restarted by the entrypoint program.
• OPENVPN_MSSFIX environment variable
• Upgrade Openvpn to 2.5.0

Servers

• Update Nordvpn hardcoded servers list

Bug fixes

• Openvpn restart loop because of ping-restart options, now replaced by ping-exit.

Documentation

• Most documentation moved to the Wiki (reached the Docker hub readme limit of 25KB)

Maintenance

• Configure dependabot to monitor go modules and docker dependencies
• Update and improve development container configuration
• Update golibs and its params package
• OpenVPN BuildConf arity reduced
• Unit test internal/provider/utils.go
• Update golangci-lint to v1.35.2

CI

• All build workflows merged into a single yml configuration file
• Go mod tidy check
• Remove duplicate COPY in Dockerfile
• Fix xcputranslate version and uage
• Set default BUILDPLATFORM=linux/amd64 in Dockerfile for older Docker CLIs

v3.11.1 Fix DNS_KEEP_NAMESERVER behavior

Fix: DNS_KEEP_NAMESERVER

v3.11.0 small stability improvements

Bug fixes

• Unbound log lines processing (showing an ERROR where it was an INFO level)

Features

• Log healthcheck: passed once the healthcheck succeeds after a failed attempt
• Unbound now serves clients from any IP address and not just localhost (access-control: 0.0.0.0/0 allow)
• Improved logging of DNS settings
• s390x and ppc64le CPU architectures supported

Code maintenance

• Using qdm12/dns Go API v1.4.0-rc3
• Using qdm12/updated Go API
• Rework main function
• Add waitgroup to collectStreamLines for a cleaner shutdown

Continuous integration

• Test, lint and build using the native builder CPU architecture only even for cross CPU architecture builds, speeding up builds from 15 minutes to about 5 minutes.
• Change workflow structure and Dockerfile structure, 'glued' together using Docker Buildkit and target images.
• Remove microbadger hooks for branch and release workflows
• Dependabot for Github actions added

Changes

Breaking

• Remove undocumented CLIENT_KEY environment variable (for Cyberghost only)

• Add quick links section for help and support
• Simplify support section
• More badges and metadata
