# Revision history for eventlog-socket
## 0.1.2.0 -- 2026-03-25
**Warning**: The C API exposed from this version contains breaking changes over the C API exposed from version 0.1.1.0. This is justified by the fact that the C API exposed from version 0.1.1.0 is broken and that version is deprecated and not known to be in use.
- **BREAKING**: Change `eventlog_socket_wrap_hs_main` to accept `EventlogSocketAddr` and `EventlogSocketOpts` and call `eventlog_socket_init`.
- **BREAKING**: Remove `eventlog_socket_attach_rts_config`.
- Fixed issue where `eventlog_socket_start` would ignore `eso_wait`.
- Fixed issue where `EventlogSocketWriter->writeEventLog` would drop data if there was no connection, resulting in a truncated eventlog.
- Fixed race condition between the calls to `endEventLogging` and `startEventLogging` that happened on startup and at first connection. If these restarts were interleaved, this could lead to the startup call to `endEventLogging` immediately detaching the event logger attached by the call to `startEventLogging` in the worker thread listening for incoming connections. This would cause the socket to immediately be closed and lead to a truncated eventlog. Furthermore, the startup call to `endEventLogging` happened unconditionally, which means that an event logger attached in a C main (as in `examples/fibber-c-main`) would be detached on the first connection, which would drop prior all events from the buffer. The new version does not call `endEventLogging` or `startEventLogging` on startup. This means that an event logger installed in a C main is able to capture events from before the first connection. It also means that the default event logger – which may be the file event logger – will be active until the first connection, rather than until `eventlog_socket_start` is called.
- Add `testWorkerStatus` and `testControlStatus` functions to Haskell API.
- Add `eventlog_socket_worker_status` and `eventlog_socket_control_status` to C API.
## 0.1.1.0 -- 2026-02-23
- Added high-level API (`startWith` with `EventlogSocketAddr` and `EventlogSocketOpts`).
- Added support for TCP sockets (via `EventlogSocketAddr`).
- Added support for setting the send buffer size (via `EventlogSocketOpts`).
- Added support for reading the configuration from environment variables (`fromEnv` and `startFromEnv`).
- Added public C API.
- Added support for control commands (if compiled with `+control`).
- Added support for custom control commands.
## 0.1.0.0 -- 2023-04-14
- First version. Released on an unsuspecting world.
