Release 1.1.1

1.1.1 - 2025-11-03

⛑️ Fixed

• We fixed a critical file descriptor handling bug introduced in v1.1.0. The Rust Edition 2024 migration incorrectly used OwnedFd instead of BorrowedFd in the enable_close_on_exec() and disable_close_on_exec() functions, causing file descriptors to be closed prematurely and breaking Sōzu's operation. This has been corrected by using BorrowedFd::borrow_raw() which only borrows the file descriptor without taking ownership, see PR #1181, fd68885a.

✍️ Changed

• We fixed the RPM spec file to enable successful builds on COPR, EPEL 10, and Fedora 42+. Changes include: adding missing build dependencies (rust, cargo, protobuf-compiler, gcc), fixing changelog date formatting, improving FHS compliance with proper use of _rundir and _sharedstatedir macros, simplifying the build mode logic, and resolving SELinux policy installation issues, see PR #1182.
• We applied clippy suggestions for code quality improvements in request builder, display modules, and backend error handling, see 28fff561.

1.1.0

1.1.0 - 2025-10-29

⚠️ BREAKING CHANGE: This release requires Rust 1.85.0 or later (previously 1.80.0) due to the migration to Rust Edition 2024. Please ensure your toolchain is updated before upgrading.

🌟 Features

• OpenTelemetry Support: We have added comprehensive OpenTelemetry integration for distributed tracing and observability. Sōzu now supports traceparent and tracestate headers in access logs, enabling seamless integration with OpenTelemetry-compatible monitoring systems. This significantly improves the ability to trace requests across distributed systems, see PR #1176, 7035eebb, f72bb977, fbce7f65.

• Sōzu as a Library: The bin crate has been restructured to allow Sōzu to be used as a library in other Rust packages. This enables embedding Sōzu's reverse proxy functionality directly into your applications, see PR #1165, 3f5f63fa.

• Cross-platform Improvements: We have improved build support for non-x86_64 architectures, particularly MacOS ARM. Kawa's SIMD features are now properly disabled on non-x86_64 platforms, resolving build issues on ARM architectures, see PR #1136, 2f478d08.

⛑️ Fixed

• We fixed an issue with incorrect backend_response_time metric calculation on keep-alive requests, see 5f3371b7.
• We fixed improper quoting in the forwarded header field, see PR #1175, 3c660faf.
• We fixed path resolution issues when saving state, ensuring relative paths are properly handled, see PR #1171, a7ecc65a.
• We fixed security vulnerability RUSTSEC-2024-0402, see PR #1168, 9d1fbbe9.
• We fixed the Dockerfile build process, see PR #1163, 93a4ea43.
• We fixed CI issues with bombardier by updating the Go version, see PR #1172, a1138973.

✍️ Changed

• Rust Edition 2024 Migration: The entire workspace has been migrated to Rust Edition 2024, requiring Rust 1.85.0 or later. This migration includes automatic formatting updates, import reorganization, added unsafe blocks for environment variable access, modernized macro syntax, and applied clippy suggestions, see PR #1179, 6650be58.
• We updated multiple dependencies to their latest versions, including general dependency bumps and Cargo.lock updates, see PR #1177, f96444e9, 703a3df3, e678ebc2.
• We avoided duplicate crates in the dependency tree to improve build times and binary size, see PR #1170, e3f81b46.
• We removed the double definition of the global allocator in the lib crate, see 6e3e7e12.
• We improved CI/CD by configuring Docker build and push on every commit, see PR #1166, a77c928f.
• We removed coverage upload from CI, see b9f0e52d.

➖ Removed

• We removed @Keksoj from CODEOWNERS, see ebdda472.

📚 Documentation

• We added missing CHANGELOG entries for versions 1.0.5 and 1.0.6, see e0017baf.
• We fixed documentation for query commands, see PR #1164, e89e1a40.

Full Changelog: 1.0.5...1.0.6

1.0.5

This changelog entry contains change from the version 1.0.3 to 1.0.5

🚀 Performance

• We have found that compiling Sōzu without logs-trace and logs-debug flags lead to a 30% less performance. In fact with flags, the rust compiler is able to track the format! macro to the write_fmt method which allow him to write on stdout without allocating memory which is not the case without and the dead code eliminator is not able to correctly do its works. The compiler without the flags is required to perform the memory allocation that lead to the 30% less performance, see 57b8d66.

⛑️ Fixed

• We fixed a corner case that may appear during the exchange of payload between Sozu, the kernel and the http client when the payload is fully transfered from the backend and sozu, but still in the kernel waiting for the client to acknowledge previous frame, see 1e6b38d.

Full Changelog: https://github.com/sozu-proxy/sozu/compare/1.0.0..1.0.2

Release 1.0.0

This is the first release of Sōzu which is a huge steps since the beginning of the project.
We would like to thanks every people involved in the development of Sōzu.
The next steps is to implements h2(c) on top of kawa with a rework of session to be able to use http 1.x clients with h2 backends and h2 clients with h2 backends, h2 clients with http 1.x backends.

🌟 Features

• This release is the first one that use protobuf-everywhere. It means that we are moving out from the old exchange model for sockets (which are data exchanges between main process and workers processes and also main process and control plane process) that use Rust structures that we serialize into json to structures described in protobuf that generate Rust source code and then communicate with binary format. Besides, this work also have some nice side-effects on fork when creating new workers (due to a self-healing or at start) which allow to reduce the time to configure a worker by around 50%. It also introduces a new way to emit access logs in a binary way, see [ dfacdb7 ], [ a6ffebe ], [ fb11245 ], [ 6daf43c ], [ 8e81a02 ], [ 24a941b ], [ 6d160b4 ], [ e382a1c ], [ 4f2d760 ], [ 6d43eb1 ] and [ 5852c6b ].
• We have reworked emitted logs and access logs format, if you are tools that parse them, you have to take a look at the new one. Besides, it will be easier to parse. Furthermore, we have added color on logs to improve readability, see [ 0885863 ], [ d3eeddc ], [ 3bb3997 ] and [ 5f55561 ].
• We have bump the minimum Rust supported version to v1.74.0, see [ 2c4363d ], [ 96f5329 ] and [ e6bcfe0 ].
• We have introduce a way to define custom http response for a wide range of status code, see 3f0bfa1, 4923153, b9df0c1, ee2430f, 3030944, 6023216, 55242ba, 55242ba, 8faa16c, a5058c2, fb6aad9 and a2236d1.
• We also fix a bug that could occur on some streaming https requests with tcp-keepalive when going through multiple Sōzu which does not flush correctly the ending chunk of data when calling rustls::write_vectored, see d83f399.
• We also change how works timeout on frontends as it is now closed by the backend, once we have received a first chunk of data, see 6114e17.

🚀 Performance

• Thanks to the work achieved on Rustls (v0.23.0) with the help of maintainers (a huge thanks to them ❤️), we have gain between 10% and 20% performance on https requests depending of the workload, see [ 7fa680d ].

⛑️ Fixed

• We have fixed a bug that occurs during http request when doing streaming and tcp keep-alive which prevent to send the close-delimiter on response, see [ 59c0615 ].
• We have fix a few bugs on certificate replacement and improve the resolution of certificates, see [ 6aa45b9 ].
• We have fix a bug that involved timeout on frontend sockets which did not take the given value, see [ d20e759 ].

✍️ Changed

• We have work on errors to have a better context when something happens, see [ ba8b51a ], [ 629551f ] and [ 1c90c04 ].

📚 Documentation

• We have added some documentation about logs and access logs, see [ d44b227 ] and [ 7241c0e ].
• We have reworked or improved examples, see [ 31bc55e ] and [ 95624e6 ].
• We have added some documentation of using Sōzu with firewalld (thanks @obreidenich), see [ 4cba552 ].
• We have setup a github continuous integration to provides and document a way to benchmark Sōzu (values on the ci are not reliable), see [ 8df9ba5 ].

This changelog is the first release candidate before the version 1.0.0, its goal is to allow to migrate smoothly other crates as the sozu-client to be compatible with the protobuf-everywhere part and to be able to make tests on production at Clever-Cloud by doing some A/B testing.

🌟 Features

• This version is the first one that use protobuf-everywhere. It means that we are moving out from the old exchange model for sockets (which are data exchanges between main process and workers processes and also main process and control plane process) that use Rust structures that we serialize into json to structures described in protobuf that generate Rust source code and then communicate with binary format. Besides, this work also have some nice side-effects on fork when creating new workers (due to a self-healing or at start) which allow to reduce the time to configure a worker by around 50%. It also introduces a new way to emit access logs in a binary way, see [ dfacdb7 ], [ a6ffebe ], [ fb11245 ], [ 6daf43c ], [ 8e81a02 ], [ 24a941b ], [ 6d160b4 ], [ e382a1c ], [ 4f2d760 ], [ 6d43eb1 ] and [ 5852c6b ].
• We have reworked emitted logs and access logs format, if you are tools that parse them, you have to take a look at the new one. Besides, it will be easier to parse. Furthermore, we have added color on logs to improve readability, see [ 0885863 ], [ d3eeddc ], [ 3bb3997 ] and [ 5f55561 ].
• We have bump the minimum Rust supported version to v1.74.0, see [ 2c4363d ], [ 96f5329 ] and [ e6bcfe0 ].

⛑️ Fixed

• We have fixed a bug that occurs during http request when doing streaming and tcp keep-alive which prevent to send the close-delimiter on response, see [ 59c0615 ].
• We have fix a few bugs on certificate replacement and improve the resolution of certificates, see [ 6aa45b9 ].
• We have fix a bug that involved timeout on frontend sockets which did not take the given value, see [ d20e759 ].

🚀 Performance

• Thanks to the work achieved on Rustls (v0.23.0) with the help of maintainers (a huge thanks to them ❤️), we have gain between 10% and 20% performance on https requests depending of the workload, see [ 7fa680d ].

✍️ Changed

• We have work on errors to have a better context when something happens, see [ ba8b51a ], [ 629551f ] and [ 1c90c04 ].

📚 Documentation

• We have added some documentation about logs and access logs, see [ d44b227 ] and [ 7241c0e ].
• We have reworked or improved examples, see [ 31bc55e ] and [ 95624e6 ].
• We have added some documentation of using Sōzu with firewalld (thanks @obreidenich), see [ 4cba552 ].
• We have setup a github continuous integration to provides and document a way to benchmark Sōzu (values on the ci are not reliable), see [ 8df9ba5 ].
