Ergo Framework v3.2.0 - Production-Ready Enterprise Features
For Elixir developers: Ergo brings OTP design patterns to Go, enabling seamless interoperability between Go and
Elixir/Erlang services in the same cluster. With mTLS and NAT support in v3.2.0, you can now build heterogeneous distributed systems where Go services (leveraging Go’s performance for CPU-intensive tasks) work alongside your Elixir applications using the same familiar patterns - Supervisors, GenServers, monitors, links, and more. The Erlang protocol implementation remains MIT-licensed for unrestricted commercial use.
The Ergo Framework has released version 3.2.0, focusing on enterprise deployment scenarios and production reliability.
Key Enterprise Features
Mutual TLS Support - New gen.CertAuthManager interface enables full mTLS with CA pool management (ClientCAs, RootCAs,
ClientAuth, ServerName). Essential for zero-trust security architectures. See
Mutual TLS | Ergo Framework documentation documentation.
NAT/Load Balancer Support - New RouteHost and RoutePort options in gen.AcceptorOptions allow nodes to run behind NAT or
load balancers with proper address advertisement. Critical for cloud deployments. See
Behind the NAT | Ergo Framework documentation documentation.
Spawn Time Control - InitTimeout option limits ProcessInit duration (max 15 seconds for remote spawn), preventing hung
initialization from blocking the system. See Process | Ergo Framework documentation documentation.
Application Tags & Role Mapping - New Tags field enables blue/green deployments, canary releases, and maintenance mode
selection. New Map field provides logical role-to-process mapping. See Application | Ergo Framework documentation
documentation.
Critical Bug Fix
Fixed critical bug where terminate signals (Link/Monitor exits) were incorrectly rejected due to wrong incarnation
validation in network layer. Thanks to qjpcpu (Jason) · GitHub for reporting
Fix: unable to send termination message to remote monitor due to incorrect creation time check by qjpcpu · Pull Request #248 · ergo-services/ergo · GitHub .
Enhanced API
Extensive API additions across gen.Node, gen.Process, and gen.Meta interfaces:
- Synchronous Call* methods from Node interface
- Priority-based delayed sends (SendWithPriorityAfter)
- Important delivery for responses
- Reference deadline tracking (gen.Ref.Deadline, IsAlive)
- Process/name resolution methods
Architecture Improvements
- Target Manager completely reworked with improved architecture and comprehensive test coverage
- Pub/Sub mechanism completely reworked for improved reliability and performance
- ProcessInit state enhanced - more methods now available during initialization (Link, Monitor, Call, RegisterName,
CreateAlias) - Graceful shutdown with configurable timeout and detailed process state logging
Developer Experience
- pprof labels for actor goroutines (with --tags pprof) - identify stuck processes instantly
- Comprehensive documentation rewritten and included in repository at https://docs.ergo.services
