# Version 1.1.2

+ Renamed the `mec_blocking()` trade-off argument from `alpha` to `rho`
to avoid confusion with the hurdle Gamma shape parameter. The old `alpha`
argument remains accepted as an undocumented compatibility alias.
+ Added `join_records()` to join files after the MEC
record linkage procedure.

# Version 1.1.1

+ Improved `mec_blocking()` by using inverted unsupervised MEC.
+ Added the trade-off argument in `mec_blocking()` for controlling the FLR-MMR trade-off.

# Version 1.1.0

+ Added `mec_blocking()` for blocked unsupervised MEC with pooled training
and blockwise prediction using the `blocking` package.
+ Added support for creating comparison vectors on a supplied table of record pairs
through the `pairs` argument in `comparison_vectors()`.
+ Added `census` and `cis` example datasets for larger record linkage examples.
+ Added a vignette showing MEC with blocking on the `cis` and `census` datasets.
+ Added optional progress messages via the `verbose` argument in `mec()`,
`train_rec_lin()`, `predict.rec_lin_model()`, and `mec_blocking()`.
+ Improved validation of supplied match and pair tables, including clearer checks
for row indices, duplicate pairs, missing values, and non-finite comparison values.
+ Improved print methods for linkage results, including consistent percentage
formatting for error rates.

# Version 1.0.1

+ Fixed CRAN errors.

# Version 1.0.0

+ Implemented comparison functions `abs_distance()` and `jarowinkler_complement()`.
+ Added support for comparing two datasets using comparison functions.
+ Added support for training a supervised record linkage model using probability or density ratio estimation,
based on the following methods: `"binary"`, `"continuous_parametric"`, and `"continuous_nonparametric"`.
+ Added support for creating a supervised record linkage model using a custom machine learning (ML) classifier.
+ Added support for predicting matches based on a record linkage model.
+ Added the unsupervised maximum entropy classification (MEC) algorithm for record linkage.
Supported methods are: `"binary"`, `"continuous_parametric"`, `"continuous_nonparametric"`, and `"hit_miss"`.
+ Added support for creating the predicted set of matches based on: its estimated size, a target false link rate (FLR)
or a target missing match rate (MMR).
+ Implemented S3 methods for printing.
+ Added support for evaluation when true matches are known.
+ Added documentation and examples.
