CRITICAL: Windows Support Discontinued
This release officially removes support for running AvalancheGo natively on Windows. All users on Windows must now use the Windows Subsystem for Linux (WSL).
IMPORTANT: Plugin Version Update
The plugin version has been updated to 42. If you run custom Subnet VMs or other plugins, they must be updated to remain compatible.
This update is optional but encouraged for all node operators. It is backwards compatible to v1.13.0.
New Features & Metrics
- New Metrics: Added the avalanche_snowman_blks_built_time_skew metric to measure block timestamp deviation and bloomfilter_hit_rate metrics to monitor the efficiency of the P2P gossip layer for the P-chain, X-chain, and C-chain.
- API Routing: HTTP requests can now be routed via the Avalanche-Api-Route header, providing more flexibility for API clients and tools that handle both HTTP/1.1 and HTTP/2.
Key Fixes
- Plugin Stability: Fixed a significant bug where HTTP headers (like CORS headers) were not correctly forwarded to plugins. Other fixes improve error handling for plugins.
- Wallet Fix: Corrected an issue where the Primary Network Wallet failed to parse C-chain shared memory UTXOs.
- Performance: The PlatformVM now throttles block building while it is bootstrapping, preventing periods of high resource usage on startup.
This version is backwards compatible to [v1.13.0](https://github.com/ava-labs/avalanchego/releases/tag/v1.13.0). It is optional, but encouraged. The plugin version is updated to `42` all plugins must update to be compatible. **This release removes the support for running on Windows. Any users running on Windows should utilize Windows Subsystem for Linux.** ## APIs - Converted HTTP2 support to route by the `Avalanche-Api-Route` header. - Added `avalanche_snowman_blks_built_time_skew` metric. - Added p2p `bloomfilter_hit_rate` metrics for the P-chain, X-chain, C-chain atomic, and C-chain mempools. ## Fixes - Fixed HTTP2 update request handling. - Fixed plugin handling of special errors during HTTP request handling. - Fixed plugin forwarding of HTTP headers. - Fixed C-chain shared memory UTXO parsing by the Primary Network Wallet. ## What's Changed - chore: move windows from tier 3 to unsupported by @aaronbuchwald in https://github.com/ava-labs/avalanchego/pull/4031 -
