Added

• #1525, Allow http status override through response.status guc - @steve-chavez
• #1512, Allow schema cache reloading with NOTIFY - @steve-chavez
• #1119, Allow config file reloading with SIGUSR2 - @steve-chavez
• #1558, Allow 'Bearer' with and without capitalization as authentication schema - @wolfgangwalther
• #1470, Allow calling RPC with variadic argument by passing repeated params - @wolfgangwalther
• #1559, No downtime when reloading the schema cache with SIGUSR1 - @steve-chavez
• #504, Add log-level config option. The admitted levels are: crit, error, warn and info - @steve-chavez
• #1607, Enable embedding through multiple views recursively - @wolfgangwalther
• #1598, Allow rollback of the transaction with Prefer tx=rollback - @wolfgangwalther
• #1633, Enable prepared statements for GET filters. When behind a connection pooler, you can disable preparing with db-prepared-statements=false
  • This increases throughput by around 30% for simple GET queries(no embedding, with filters applied).
• #1729, #1760, Get configuration parameters from the db and allow reloading config with NOTIFY - @steve-chavez

• #1881, Add openapi-mode config option that allows ignoring roles privileges when showing the OpenAPI output - @steve-chavez
• CLI options(for debugging):
  • #1678, Add --dump-config CLI option that prints loaded config and exits - @wolfgangwalther
  • #1691, Add --example CLI option to show example config file - @wolfgangwalther
  • #1697, #1723, Add --dump-schema CLI option for debugging purposes - @monacoremo, @wolfgangwalther
• #1794, (Experimental) Add request.spec GUC for db-root-spec - @steve-chavez

Fixed

• #1592, Removed single column restriction to allow composite foreign keys in join tables - @goteguru
• #1530, Fix how the PostgREST version is shown in the help text when the .git directory is not available - @monacoremo
• #1094, Fix expired JWTs starting an empty transaction on the db - @steve-chavez

• #1469, #1638 Fix overloading of functions with unnamed arguments - @wolfgangwalther
• #1560, Return 405 Method not Allowed for GET of volatile RPC instead of 500 - @wolfgangwalther
• #1584, Fix RPC return type handling and embedding for domains with composite base type (#1615) - @wolfgangwalther
• #1608, #1635, Fix embedding through views that have COALESCE with subselect - @wolfgangwalther
• #1572, Fix parsing of boolean config values for Docker environment variables, now it accepts double quoted truth values ("true", "false") and numbers("1", "0") - @wolfgangwalther
• #1624, Fix using app.settings.xxx config options in Docker, now they can be used as PGRST_APP_SETTINGS_xxx - @wolfgangwalther
• #1814, Fix panic when attempting to run with unix socket on non-unix host and properly close unix domain socket on exit - @monacoremo
• #1825, Disregard internal junction(in non-exposed schema) when embedding - @steve-chavez
• #1846, Fix requests for overloaded functions from html forms to no longer hang (#1848) - @laurenceisla
• #1858, Add a hint and clarification to the no relationship found error - @laurenceisla
• #1841, Show comprehensive error when an RPC is not found in a stale schema cache - @laurenceisla
• #1875, Fix Location headers in headers only representation for null PK inserts on views - @laurenceisla

Changed

• #1522, #1528, #1535, Docker images are now built from scratch based on a the static PostgREST executable (#1494) and with Nix instead of a Dockerfile. This reduces the compressed image size from over 30mb to about 4mb - @monacoremo
• #1461, Location header for POST request is only included when PK is available on the table - @wolfgangwalther
• #1560, Volatile RPC called with GET now returns 405 Method not Allowed instead of 500 - @wolfgangwalther
• #1584, #1849 Functions that declare returns composite_type no longer return a single object array by default, only functions with returns setof composite_type return an array of objects - @wolfgangwalther
• #1604, Change the default logging level to log-level=error. Only requests with a status greater or equal than 500 will be logged. If you wish to go back to the previous behaviour and log all the requests, use log-level=info - @steve-chavez
  • Because currently there's no buffering for logging, defaulting to the error level(minimum logging) increases throughput by around 15% for simple GET queries(no embedding, with filters applied).
• #1617, Dropped support for PostgreSQL 9.4 - @wolfgangwalther
• #1679, Renamed config settings with fallback aliases. e.g. max-rows is now db-max-rows, but max-rows is still accepted - @wolfgangwalther
• #1656, Allow Prefer=headers-only on POST requests and change default to minimal (#1813) - @laurenceisla
• #1854, Dropped undocumented support for gzip compression (which was surprisingly slow and easily enabled by mistake). In some use-cases this makes Postgres up to 3x faster - @aljungberg
• #1872, Send startup/worker logs to stderr to differentiate from access logs on stdout - @steve-chavez
