1.10.1

What's Changed

• Use pg14 as an example for instructions instead of pg13. Add reference to deb and rpm packages by @jerryxwu in #463
• Document supported platforms. by @epgts in #467
• Fixing off by one error in state_agg interpolate by @WireBaron in #465

Note that the 1.10.1 patch release is to fix an issue where the 1.9.0 release unintentionally identified the toolkit extension version as 1.10.0-dev in the postgresql control file.

Full diff since v1.6.0

1.6.0

This release includes new and updated experimental functionality, as well as some internal updates.

Experimental Features

• #370 Implement a TopN (topn_agg) variant of our freq_agg
• #375 Add prototype gauge_agg and associated functions delta, idelta_left, idelta_right, rollup
• #368 Add into_values function for state_agg
• #330 improvements to freq_agg
• #351 Make serialize functions strict to handle NULL values in partitioned aggregates

Internal Improvements

• #332 #377 improve build and test scripts

1.5.2

This release contains bug fixes since the 1.5.0 release.
This release is high priority for upgrade. We strongly recommend that you
upgrade as soon as possible.

Bug Fixes

• PR #351 - Make serialize functions strict
• There's a vulnerability in Toolkit 1.5 and earlier due to the fact that it creates a PLPGSQL function using CREATE OR REPLACE and without properly locking down the search path. This means that a user could pre-create the trigger function to run arbitrary code. To fix this we remove the trigger entirely; it no longer pulls its weight. This fix locks down our update scripts to only use CREATE OR REPLACE when actually necessary; while we don't yet have an exploit for the other functions, it would be unsurprising if one exists.

1.5.0

This release includes new experimental functionality, as well as some internal updates.

Experimental Features

• freq_agg for estimating the most common elements in a column
• state_agg for measuring the total time spent in different states

Internal Improvements

• Updated rust to 1.57
• Enforce clippy linting
