DESCRIPTION.Update to duckdb v1.1.3, see https://github.com/duckdb/duckdb/releases/tag/v1.1.3 for details.
New duckdb.materialize_callback option, supersedes
get_last_rel() (#589).
New rel_explain_df() and rel_tostring()
(#587).
Handle empty child values for list constants (#186, @romainfrancois).
Undef TRUE and FALSE (#595).
Remove enable_materialization argument to
rel_from_altrep_df() in favor of creating a new data frame
when needed (#588).
Flip argument order for expr_comparison()
(#585).
Keep cleanup files to accommodate different build
scenarios (#536).
Long-running queries can now be canceled immediately with Ctrl + C (terminal) or Escape (RStudio IDE and Workbench) (#514, #515).
Add col.types argument to
duckdb_read_csv() (#445, @eli-daniels).
Rethrow errors with rlang if installed (#522).
Improve error message for parsing erros during statement extraction (tidyverse/duckplyr#219, #521).
Avoid RStudio IDE crashes when ending session with open objects (#520).
rfuns extension: %in% works correctly
as part of a & conjunction (#528).
New interal APIs: rapi_get_last_rel_mat(),
rapi_rel_to_altrep(allow_materialization = TRUE),
rapi_rel_from_altrep_df(enable_materialization)
(#526).
xz-compress duckdb sources in the tarball (#530).

Update to duckdb v1.1.0, see https://github.com/duckdb/duckdb/releases/tag/v1.1.0 for details.
Upgrade vendored cpp11 to 0.5.0.
Upgrade vendored cpp11 to 0.4.7 to fix compilation with R-devel.
Support dplyr::tbl(conn, I(...)).
MAP type (#61, #165).clock::date_count_between()
(@edward-burn,
#163, #166).round() duckdb translation uses
ROUND_EVEN() instead of ROUND() (@lschneiderbauer,
#146, #157).sort argument to rel_order() (@toppyy, #168).clock::add_days(),
clock::add_years(), clock::get_day(),
clock::get_month(), and clock::get_year()
(@edward-burn,
#153).win_current_group() instead of
win_current_order() in SQL translation (@lschneiderbauer,
#173, #175)."difftime" class is now mapped to the
INTERVAL data type (#151).n_distinct() for multiple arguments using
duckdb structs (@lschneiderbauer, #110, #122).NA to SQLNULL (#143).rel_sql(rel, "{{sql}}") works even on a read-only
database (@Tmonster,
#138).R CMD check warning regarding
SETLENGTH() and SET_TRUELENGTH() (#145).duckdb(). A database file is closed (and available to be
opened from another session) after the last connection that uses this
file calls dbDisconnect() . The shutdown
argument to dbDisconnect() or the
duckdb_shutdown() functions are no longer necessary. Two
database connections from the same R session can access the same file
concurrently in read-write mode (#124).Don’t run tests that invoke re2 by default (#121, #127).
Fix compilation for R 4.0 and R 4.1, regression introduced in
v0.10.0. Using librstrtmgr.a from UCRT build of rtools40
(#130).
The C++ core is now vendored commit by commit, once every five
minutes. Vendoring stops if R CMD check fails or if a
previously unreleased tag is reached.
New maintainer: Kirill Müller.
dplyr::tbl() works again when a Parquet or CSV file
is passed instead of a table name (#38, #91).
DBI::dbQuoteIdentifier() correctly quotes
identifiers that start with a digit (#67, #92).
Align the argument order of dbWriteTable() with the
DBI specs (@eitsupi,
#43, #49).
New tbl_file() and tbl_query() to
explicitly access tables and queries as dbplyr lazy tables (#96). The
cache argument to tbl() and to the new
functions must be named.
Initial ALTREP support for LIST logical type (@romainfrancois,
#77).
Update core to duckdb v0.10.0 (#90).
New private rel_to_parquet() to write a relation to
parquet (@Tmonster,
#46).
Change directory location for extensions and secrets for v.0.10.0 release (@Tmonster, #73).
Remove last instance of default_connection()
(#50).
