1.11.0

New Experimental Features:

• arm64/aarch64 DEB packages are now available for Ubuntu 20.04 (focal) & 22.04 (jammy), and Debian 10 (buster) & 11 (bulleye). @epgts
• #526: Add integral and interpolated_integral functions for the time_weight aggregate. Makes trapezoidal an alias for linear in time_weight as it might be a more familiar numeric integral method for some. @Smittyvb
• #517: Add a gap preserving lttb named gp_lttb to handle downsampling of data with large gaps. @WireBaron
• #513: Add first_val, last_val, first_time and last_time to time_weight and counter_agg to access the first and the last data points within the aggregate data structures. @rtwalker
• #527: Rename {open, high, low, close}_at as {open, high, low, close}_time to be consistent with newly added first_time and last_time accessor functions. @rtwalker

Stabilizing Features:

• #498: Stabilize asap_smooth aggregate. @WireBaron

Bug Fixes:

• #509, #531: Fix bugs inhyperloglog. Error rates are now significantly more consistent when the number of buckets are close to the actual cardinality. @BenSandeen @davidkohn88 @WireBaron @jerryxwu
• #514: Fix a bug in toolkit_experimental.interpolated_delta @WireBaron
• #503: Fix bitwise logic in timevector combine @WireBaron
• #507: Fix a typo in approx_count_distinct @jeremyhaberman

Other Notable Changes:

• DEB packages for Ubuntu 18.04 (Bionic) on amd64 are now available.
• #536: Document requirement to use same compiler for cargo-pgx and Toolkit
• #535: Make tests pass in Canadian locales @Smittyvb
• #537: Enforce cargo fmt in CI @Smittyvb
• #524: Updating Toolkit To Start Using Cargo Fmt @thatzopoulos
• #522: Move update-tester tests to markdown files @thatzopoulos

Shout-outs:

• @BenSandeen for fixing typos and errors in the hyperloglog++ implementation
• @jaskij for reporting security advisories and suggestion on documenting support for PG14
• @jeremyhaberman for fixing a typo in APPROX_COUNT_DISTINCT_DEFAULT_SIZE
