v2.1.4

• Rebuild release with go-1.13.8
• Experimental windows build

v2.1.3

• Rebuild release with go-1.13.5

v2.1.2

• Fix for enabling metrics collection in proxy

v2.1.1

• Security fixes / content-type validation
• Add ProxyFromEnvironment support. This uses HTTP proxies directed by the HTTP_PROXY and NO_PROXY (or http_proxy and no_proxy) environment variables. See ProxyFromEnvironment for more info.

v2.1.0

Important note regarding Response Size Limiting

The default value for --max-size was previous set to 5120 (5KB). However, chunked encoding responses bypassed size restrictions, and only content-length type responses had response size limits enforced.

This issue has been fixed. To avoid unexpected failures, and to preserve backwards compatibility in this regard, --max-size now defaults to 0 (no size limit).

To restore the previous default, as well as enforcing response size limits on content-type responses, simply pass --max-size=5120 at startup.

Changes

• Support audio/* with --allow-content-audio flag (similar to how video is handled)
• Additional metrics datapoints when using --metrics
• Support only go 1.13, due to use of new error wrapping semantics
• Improve client connection early abort handling
• Improve max response side handling -- only read MaxSize KB from any upstream server. Note: This may result in partial responses to clients for chunked encoding requests that are longer than MaxSize, as there is no way to signal the client other than closing the connection.
• Change default of --max-size to 0, as previously chunked encoding responses bypassed size restrictions (only content-length was previously enforced). To avoid unexpected failures (preserve backwards compatibility in this regard), set max-size to 0 by default moving forward. Previous default was 5mb (use --max-size=5120 to set to previous default).

v2.0.1

• Slightly optimize some structure layouts to reduce memory overhead.
• Switch htrie node map from uint8 to uint32, due to go map optimizations.
  See commit bbf7b9f for more info.
• Update man page generation (makefile) to use asciidoctor. Not only is this easier to maintain, but it has the nice property of being rendered on github.

v2.0.0

• Remove --allow-list flag, and replace with a unified filtering flag filter-ruleset. See FILTER_FORMAT.md for more information on the accepted syntax.
• Update man pages.
• Refactor some internals (remove some regex in favor of a trie like data structure for some comparisons)

v2.0.0-alpha.2

Performance and memory usage tweaks.

v2.0.0-alpha.1

• Remove --allow-list flag, and replace with a unified filtering flag filter-ruleset.
  See FILTER_FORMAT.md for more information on the accepted syntax.

v1.1.7

• Remove old stats flag, endpoint, and feature, in favor of the new
  premetheus endpoint. Good amount of code removal as well.
• Use a sync.Pool []byte buffer for io.CopyBuffer (instead of io.Copy). It
  should reduce some small amount of GC pressure (a bit less garbage).
• Build with go1.12.8 - which includes security fixes for http/2.
