Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[0.2.6] - 2018-07-31

Added

• Configurable TCP timeouts to assist in peering over Tor/I2P
• Prefer IPv6 flow label when extending coordinates to sort backpressure queues
• arm64 builds through CircleCI

Changed

• Sort dot graph links by integer value

[0.2.5] - 2018-07-19

Changed

• Make yggdrasilctl less case sensitive
• More verbose TCP disconnect messages

Fixed

• Fixed debug builds
• Cap maximum MTU on Linux in TAP mode
• Process successfully-read TCP traffic before checking for / handling errors (fixes EOF behavior)

[0.2.4] - 2018-07-08

Added

• Support for UNIX domain sockets for the admin socket using unix:///path/to/file.sock
• Centralised platform-specific defaults

Changed

• Backpressure tuning, including reducing resource consumption

Fixed

• macOS local ping bug, which previously prevented you from pinging your own utun adapter's IPv6 address

[0.2.3] - 2018-06-29

Added

• Begin keeping changelog (incomplete and possibly inaccurate information before this point).
• Build RPMs in CircleCI using alien. This provides package support for Fedora, Red Hat Enterprise Linux, CentOS and other RPM-based distributions.

Changed

• Local backpressure improvements.
• Change box_pub_key to key in admin API for simplicity.
• Session cleanup.

[0.2.2] - 2018-06-21

Added

• Add yggdrasilconf utility for testing with the vyatta-yggdrasil package.
• Add a randomized retry delay after TCP disconnects, to prevent synchronization livelocks.

Changed

• Update build script to strip by default, which significantly reduces the size of the binary.
• Add debug -d and UPX -u flags to the build script.
• Start pprof in debug builds based on an environment variable (e.g. PPROFLISTEN=localhost:6060), instead of a flag.

Fixed

• Fix typo in big-endian BOM so that both little-endian and big-endian UTF-16 files are detected correctly.

[0.2.1] - 2018-06-15

Changed

• The address range was moved from fd00::/8 to 200::/7. This range was chosen as it is marked as deprecated. The change prevents overlap with other ULA privately assigned ranges.

Fixed

• UTF-16 detection conversion for configuration files, which can particularly be a problem on Windows 10 if a configuration file is generated from within PowerShell.
• Fixes to the Debian package control file.
• Fixes to the launchd service for macOS.
• Fixes to the DHT and switch.

[0.2.0] - 2018-06-13

Added

• Exchange version information during connection setup, to prevent connections with incompatible versions.

Changed

• Wire format changes (backwards incompatible).
• Less maintenance traffic per peer.
• Exponential back-off for DHT maintenance traffic (less maintenance traffic for known good peers).
• Iterative DHT (added some time between v0.1.0 and here).
• Use local queue sizes for a sort of local-only backpressure routing, instead of the removed bandwidth estimates, when deciding where to send a packet.

Removed

• UDP peering, this may be added again if/when a better implementation appears.
• Per peer bandwidth estimation, as this has been replaced with an early local backpressure implementation.

[0.1.0] - 2018-02-01

Added

• Adopt semantic versioning.

Changed

• Wire format changes (backwards incompatible).
• Many other undocumented changes leading up to this release and before the next one.

[0.0.1] - 2017-12-28

Added

• First commit.
• Initial public release.
