• Basic AWS Athena support by @sh-rp in #522
  A data lake destination which works together with filesystem as a staging

Apart from that bug fixes:

• fixes airflow provider init sequence by @rudolfix in #569
• fixes transformer decorator typings by @rudolfix in #554

Docs

Full Changelog: 0.3.10...0.3.12

0.3.10

Core Library

• Fix config dataclasses on python 3.11 by @steinitzu in #541
  Now P3.11 is fully tested on CI
• removes optional dependencies by @rudolfix in #552
  sentry-sdk and several dependencies used by dlt deploy command were moved to extras. several others (including fsspec) have their minimal version set to earlier versions
• PR above is also fixing #539 and #540

Full Changelog: 0.3.9...0.3.10

0.3.9

Bugfix Release

When a replace with staging dataset was used in version 0.3.8, tables with other write dispositions were also truncated (in other words all the tables in the schema could be truncated). Note that default replace strategy does not use staging dataset so if you didn't explicitly changed you were not affected.
This release fixes that bug. If you use the replace strategy above, update the library.

Full Changelog: 0.3.8...0.3.9

0.3.8

Core Library

• use Airflow (and possibly other) schedulers with dlt resources by @rudolfix in #534
  A really cool feature that allows your incremental loading to take date ranges from Airflow schedulers. Do backfilling, incremental loading and relay on Airflow to keep the pipeline state.

• Ignore hints prefixed with 'x-' in table_schema() by @burnash in #525

• Now our CI works correctly from forks! by @steinitzu in #530

Support for unstructured data!

A really cool data source that let's you ask questions about your PDF documents and stores the answers in any of our destinations. Going from binary blobs through unstrucutred.io, vector databases and LLM queries to ie. duckdb and bigquery. Blobs coming from filesystem, google drive or your inbox (also incrementally) by @AstrakhantsevaAA

0.3.6

Core Library

• fixes lost data and incorrect handling of child tables during truncate-and-insert replace by @sh-rp in #499
  This is important improvement that fixes a few holes in truncate-and-insert replace mode (which was there from beginning of dlt). Now we truncate all the tables before multithreaded append process starts. We also truncate child tables that could be left with data before.
  details: #263 #271

0.3.5

Core Library

• Fix incremental hitting end_value throwing out whole batches by @steinitzu in #495
