v2.3.0

v2.3.0

Caddy 2.3 is the first web server to be able to get certificates from multiple issuers (for redundancy)! We've also optimized several things for large-scale deployments, as there are businesses using Caddy to serve tens of thousands of sites per instance.

The main highlights of this release include:

Multi-issuer support. Caddy can now get certificates from multiple issuers for redundancy; if one fails, another will be tried. Caddy's new defaults are Let's Encrypt and ZeroSSL. You can customize these, including adding local/self-signed certificates as a last resort if desired. Caddy is the first web server to support multiple issuers, offering unrivaled reliability for your site's HTTPS. It is the first ACME client to support multiple CA fallbacks.
Improved on-demand TLS. On-demand TLS is an operating mode by which certificate obtain/renew operations are triggered on a TLS handshake that requires them, rather than happening at config-load time. We've moved a lot of the processing to the background where possible (e.g. when an existing certificate is still usable) so more connections will finish their handshakes faster, and fewer handshakes will fail (however, you still need to watch the logs and fix the errors before it's too late). Several businesses we know of currently rely on this unique feature at a scale of tens of thousands of sites.
Support for alternate certificate chains. You can now customize which certificate chains to download from ACME servers that offer more than one.
New map handler is ready for production use. (Caddyfile docs) It's been in Caddy for a few versions now but it's finally ready for production, with enhanced efficiency and functionality. We have been using this handler with a customer in production for a while now, on an instance that is handling thousands of sites.
Customize servers and listeners with the Caddyfile. The Caddyfile structure is oriented around sites for convenience, so customizing servers has not been possible until now. You can now use global options to configure servers and their listeners (for example, protocol options, socket read options, and more) without having to use JSON config.

Of course, there are also numerous bug fixes and other enhancements, including bringing more configuration options into the Caddyfile. Thank you to everyone who contributed code, code reviews, or participated in the pre-releases.

There are a couple of minor breaking changes, but one was not documented and the other has always been an experimental feature:

⚠️ The remote_ip matcher no longer reads the X-Forwarded-For header by default. This was undocumented behavior, and an unsafe default. If you happened to be relying on this, please enable forwarded (in the Caddyfile, just put forwarded as the first argument before the ranges) to maintain that behavior. Remember that headers are very easy to spoof.
⚠️ The experimental_http3 global option in the Caddyfile has been replaced with global server options, one of which is the experimental_http3 protocol. Docs will be updated shortly. This is still an unstable feature until HTTP/3 is finalized and our upstream QUIC/H3 lib is stable and we've decided to keep HTTP/3 enabled in the core by default.
⚠️ The "issuer" field in TLS automation policies is deprecated and will be removed in the future, please switch to "issuers".

Along with this release, we've taken the opportunity to consolidate our documentation regarding getting/installing Caddy. There is no more /docs/download page, instead it was combined with /docs/install which better organizes the various official and unofficial ways to get Caddy. (To be clear, our download page at /download is still available.) Also, we started using Cloudsmith for our Debian packaging -- they're donating this service to our open source project and their team has been a pleasure to work with.

This release is the work of at least 20 contributors. Thank you!

v2.3.0-rc.1 Pre-release

Pre-release

This is the first release candidate. We think 2.3 is ready to go, but we want to be extra sure! Please try it out in low-risk deployments and report any problems. Thank you!

Docs will be updated over the coming days and weeks. See the additional release notes from the beta release if you're coming from 2.2.

⚠️ The remote_ip matcher no longer reads the X-Forwarded-For header by default. This was undocumented behavior, and an unsafe default. If you happened to be relying on this, please enable forwarded (in the Caddyfile, just put forwarded as the first argument before the ranges) to maintain that behavior.

v2.2.1

v2.2.1

This patch release contains a number of bug fixes. Thanks for the reports and the help in debugging them!

Update: December 2020: This tag is the same as v2.2.3. Somehow, an unauthorized tag v2.2.2 was released from a fork. Because the Go module proxy is append-only, we created the v2.2.3 tag so that v2.2.1 would remain the default "latest" until v2.3.0 stable is released in a few weeks.

v2.2.0

f197cec

v2.2.0

We are pleased to release Caddy 2.2! Our community has spent a lot of time on bug fixes, as well as some new features you will like.

Highlights:

Full support for ZeroSSL, a new ACME CA that is a viable alternative to Let's Encrypt. Its ACME endpoint is free to use and might even be a better fit for your deployment depending on your requirements (for example, it does not have tight rate limits and does not require the DNS challenge for wildcard certs). To clarify, ZeroSSL's ACME endpoint is RFC 8555-compliant and was already compatible with Caddy; we just made it easier to use by automating the EAB credentials for your convenience.
We now have full control over our ACME stack! By replacing our previous underlying ACME library (lego) with ACMEz, Caddy can offer:
- faster config reloads
- more efficient cert management at scale
- a more intuitive configuration experience
- lighter builds
- structured logs that are consistent with Caddy's other logs (which you have fine-grained control over).
- (we no longer suffer from the limitations still shared by other lego-based ACME clients)
Integrated support for Prometheus metrics. We decided that emitting metrics is something the core of the server has to do, rather than only a separate module. We will continue improving this with time. Huge thanks to @hairyhenderson for his skillful contributions.
HTTP/2 server push has been re-introduced, this time better than it was in Caddy 1.
Caddyfile enhancements, including:
- Fully customize certificate issuers from the Caddyfile. Up until now, you could only customize certain parts of the ACME issuer or choose the Internal issuer from the Caddyfile; now you have full control.
- Named matchers can be defined inside route blocks.
- Customize log encoders.
- dns property for issuer subdirective of tls directive that allows full customization of DNS challenge (those providers which support the Caddyfile)
- Bug fixes
⚠️ The logfmt log encoder has been deprecated and will be removed. (It is already broken since it does not encode objects, so if you used it you probably stopped using it anyway.)
Customizable DNS resolver for reverse proxy
Latest HTTP/3 version
Numerous bug fixes and other enhancements! Notable bug fixes related to:
- ACME DNS challenge providers
- Custom resolvers for the DNS challenge
- ACME EAB (External Account Binding)
- Panic recovery
- Startup time when managing lots of certificates
- Correct port for active health checks (reverse_proxy module)
- Windows paths
- File hiding logic (file_server module)
- Bidirectional streaming (reverse_proxy module; specifically benefits v2ray use)
- More consistent, structured error logging when produced from HTTP code in Go's standard library
- New placeholders and log fields, especially pertaining to TLS, ACME, and HTTP

Special thanks to @francislavoie and @mohammed90 and @hairyhenderson and others in our community for their continual aid with many bug reports and feature requests.

v2.2.0-rc.2 Pre-release

Pre-release

Edit: Don't use rc2, use rc3 instead. (Released just a few hours later as a hotfix.)

The next release candidate for v2.2.0 - please try it out before the final tag! As always, deploy into a test or staging environment before production.

There are a lot of commits in this release because the milestone moved while we fixed problems that were reported, and we also wanted to make sure the final v2.2 release will be good and solid. Most of these commits are bug fixes, but we've also added Caddyfile support for several features, and notably: integrated Prometheus metrics. (Thanks @hairyhenderson and other contributors! That was a team effort.)

As you might expect, this release builds on all changes in RC1.

The documentation on our website will be updated after the final release is tagged.

v2.1.1

Version 2.1.1 fixes a minor regression in v2.1 related to the CEL (expression) matcher, as well as eliminating the warning about pb.proto. Both regressions were unfortunately introduced by patch updates on dependencies. This version also adds support for placeholders in the query matcher, and a WIP/experimental map handler that will be finalized before 2.2.

v2.1.0

v2.1.0

Caddy 2.1 introduces a variety of new features, bug fixes, and other enhancements! Highlights:

Fully automated mTLS certificates. Caddy 2.1 can fully manage all its TLS certificates -- including TLS client certificates -- using any ACME endpoint you configure. New in this version, the reverse proxy module can be configured to present an automated client certificate, just by providing its subject name in the config. We've tested it with Caddy's built-in ACME server, Let's Encrypt, Sectigo, and Smallstep ACME endpoints. Using this feature, Caddy will keep the client certificate renewed automatically.
Embedded ACME server (powered by Smallstep). This allows other ACME clients to use Caddy as an ACME endpoint. The idea here is to replace one-off self-signed, generated certificates with proper, short-lived, auto-renewing certificates for local development and internal deployments. In other words, if you're running a command every so often to produce a self-signed certificate, use Caddy instead for proper, fully-managed internal PKI. Simply add the acme_server directive to your Caddyfile for its default configuration, or use its JSON interface.
H2C support. Although discouraged in the general case, HTTP/2 over Cleartext HTTP (h2c) can be useful when serving or proxying gRPC locally/internally on trusted networks; and due to current poor TLS support in gRPC services currently, h2c might even be required in some cases. Caddy can now serve HTTP/2 without encryption, and it can communicate as a client with an HTTP/2 server that does not support TLS. To proxy h2c, set the versions property to include "h2c". To serve h2c, enable allow_h2c in your HTTP server config.
New handle_path Caddyfile directive. This works the exact same as handle, but it only accepts a path prefix matcher and it strips the matched portion of the path before executing the directives contained in its block. It's a shortcut for using handle and uri strip_prefix together, which was a common-enough use case that we consolidated it into a new directive.
Auto HTTPS can be configured in the Caddyfile. You can use the auto_https global option to disable it entirely, or disable only HTTP->HTTPS redirects. This is useful if you don't want to bind to any HTTP port at all.
Various other Caddyfile improvements. Several quality-of-life improvements for the Caddyfile, including one-line named matchers such as @foo not path /foobar/*, and the ability to use backticks (`) to enclose strings where double quotes (") are inconvenient.
Reverse proxy response interception. The reverse proxy can now intercept and handle the response from upstream based on the response status code and/or headers. This allows you to invoke custom, arbitrary HTTP logic based on the response from a backend.
Many bug fixes and other enhancements. We always say this, I know, but just look at that changelog.

Thank you to all who contributed and filed actionable bug reports as well as patches! Please keep it up. :)
