dplyr::coalesce().rel_to_df() needs prudence argument (#644).methods_overwrite() or library(duckplyr) (#641).compute() does not have a fallback, failures are reported to the client (#637).
Implement slice_head() (#640).
Sys.setenv(DUCKPLYR_FALLBACK_INFO = TRUE).Check if extensions can be loaded before running examples and vignettes (#620).
Show source of error if data frame cannot be converted to duck frame (#614).

Italicize book title in README (@wibeasley, #607).
Fix typo in filter(.by = ...) error message (@maelle, #611).
Improved support for handling large data from files and S3: ingestion with read_parquet_duckdb() and others, and materialization with as_duckdb_tibble(), compute.duckplyr_df() and compute_file(). See vignette("large") for details.
Control automatic materialization of duckplyr frames with the new prudence argument to as_duckdb_tibble(), duckdb_tibble(), compute.duckplyr_df() and compute_file(). See vignette("prudence") for details.
read_csv_duckdb() and others, deprecating duckplyr_df_from_csv() and df_from_csv() (#210, #396, #459).
read_sql_duckdb() (experimental) to run SQL queries against the default DuckDB connection and return the result as a duckplyr frame (duckdb/duckdb-r#32, #397).
db_exec() to execute configuration queries against the default duckdb connection (#39, #165, #227, #404, #459).
as_duckdb_tibble(), replaces as_duckplyr_tibble() and as_duckplyr_df() (#383, #457) and supports dbplyr connections to a duckdb database (#86, #211, #226).
compute_parquet() and compute_csv(), implement compute.duckplyr_df() (#409, #430).
fallback_config() to create a configuration file for the settings that do not affect behavior (#216, #426).
is_duckdb_tibble(), deprecates is_duckplyr_df() (#391, #392).
last_rel() to retrieve the last relation object used in materialization (#209, #375).
Add "prudent_duckplyr_df" class that stops automatic materialization and requires collect() (#381, #390).
Partial support for across() in mutate() and summarise() (#296, #306, #318, @lionel-, @DavisVaughan).
Implement na.rm handling for sum(), min(), max(), any() and all(), with fallback for window functions (#205, #566).
Handle dplyr::desc() (#550).
Avoid forwarding is.na() to is.nan() to support non-numeric data, avoid checking roundtrip for timestamp data (#482).
Correctly handle missing values in if_else().
Limit number of items that can be handled with %in% (#319).
duckdb_tibble() checks if columns can be represented in DuckDB (#537).
Fall back to dplyr when passing multiple with joins (#323).
Improve fallback error message by explicitly materializing (#432, #456).
Point to the native CSV reader if encountering data frames read with readr (#127, #469).
Improve as_duckdb_tibble() error message for invalid x (@maelle, #339).
Depend on dplyr instead of reexporting all generics (#405). Nothing changes for users in scripts. When using duckplyr in a package, you now also need to import dplyr.
Fallback logging is now on by default, can be disabled with configuration (#422).
The default DuckDB connection is now based on a file, the location defaults to a subdirectory of tempdir() and can be controlled with the DUCKPLYR_TEMP_DIR environment variable (#439, #448, #561).
explain() returns the input, invisibly (#331).
Compute ptype only for join columns in a safe way without materialization, not for the entire data frame (#289).
Internal expr_scrub() (used for telemetry) can handle function-definitions (@toppyy, #268, #271).
Harden telemetry code against invalid arguments (#321).
New articles: vignette("large"), vignette("prudence"), vignette("fallback"), vignette("limits"), vignette("developers"), vignette("telemetry") (#207, #504).
New flights_df() used instead of palmerpenguins::penguins (#408).
Move to the tidyverse GitHub organization, new repository URL https://github.com/tidyverse/duckplyr/ (#225).
Avoid base pipe in examples for compatibility with R 4.0.0 (#463, #466).
Comparison expressions are translated in a way that allows them to be pushed down to Parquet (@toppyy, #270).
Printing a duckplyr frame no longer materializes (#255, #378).
Prefer vctrs::new_data_frame() over tibble() (#500).
df_from_file() and related functions support multiple files (#194, #195), show a clear error message for non-string path arguments (#182), and create a tibble by default (#177).as_duckplyr_tibble() to convert a data frame to a duckplyr tibble (#177).?df_from_file shows how to read multiple files (#181, #186) and how to specify CSV column types (#140, #189), and is shown correctly in reference index (#173, #190).as.integer(), NA and %in% (#83, #154, #148, #155, #159, #160).library(duckplyr) calls methods_overwrite() (#164).grepl().intersect(), setdiff(), symdiff(), union(), and union_all() (#169).NA and those used in an expression (#157).head(-1) forwards to the default implementation (#131, #156).left_join() and other join functions call auto_copy().row_number() returns integer.is.na(NaN) is TRUE.summarise(count = n(), count = n()) creates only one column named count.?df_from_file (@andreranza, #133, #134).vec_ptype() does not materialize (#149).expect_identical() to capture differences between doubles and integers.df_to_parquet() to write to Parquet, new convenience functions df_from_csv(), duckdb_df_from_csv(), df_from_parquet() and duckdb_df_from_parquet() (#87, #89, #96, #128).summarise() (#72, #106).summarise() no longer restores subclass.log10() and log().fallback_sitrep() and related functionality for collecting telemetry data (#102, #107, #110, #111, #115). No data is collected by default, only a message is displayed once per session and then every eight hours.
