The primary branch release of nginx 1.19.10 has been formed, continuing the development of new features (only changes related to fixing critical bugs and vulnerabilities are made in the concurrently supported stable branch 1.18).
Key Changes:
- The default value of the ‘keepalive_requests’ parameter, which defines the maximum number of requests that can be sent over a single keep-alive connection, has been increased from 100 to 1000.
- A new directive ‘keepalive_time’ has been added, which limits the total lifetime of each keep-alive connection, after which the connection will be closed (not to be confused with keepalive_timeout, which defines the inactivity period after which a keep-alive connection is closed).
- A new variable $connection_time has been added, through which you can obtain information about the connection duration in seconds with millisecond precision.
- A workaround has been added to address the issue of warnings in the log stating ‘gzip filter failed to use preallocated memory’ when using the zlib-ng library.
