model_income_tax Arguments prefixed Budget_ and lito_ are deprecated and now offsets = set_offsets are preferred. However, using System with income_tax is likely to be just as convenient.
lito and lmito no longer accept varying parameters, but lmito is now exported
sapto_rcpp, income_tax_sapto, new_income_tax, new_medicare_levy, and new_sapto have now been removed. Use System.

In particular, _inflator functions and related forecasting methods, functions essentially accessing ABS data, and functions relating to tranfers will be put in other packages, and imported later. Functions that are made available in the grattan NAMESPACE may have changes to their API when this happens.
income_tax now uses System to define the tax systemmodel_income_tax does not throw an error for incorrect specification of lito_ arguments (which are deprecated)age_grouper now works with long vectors containing missing valuesrent_assistance() example no longer works because of outdated data.income_tax and medicare_levy no longer accept family_status as an input, since it was giving misleading results. Use .dots.ATO with appropriate variables to define the spouse’s income or the number of children.income_tax gives a slightly different error message when an invalid financial year is passed. Previously “not in correct form”, now “not a valid financial year”.useABSConnection = TRUE is no longer supported because of ABS server issuesprojectproject now has r_super_balance to project super balances by a user-supplied factor, rather than a hard-coded 1.05.package:rsdmx is now Suggested, since a dependency has been orphaned.grattan’s tax modelling functions now work with the 2016-17 ATO sample filegrattan now depends on R 3.5.0 due to serialization format version 3 becoming the default in R 3.6.0.cpi_inflator fails more gracefully when the ABS’s website is not availableincome_tax now gives consistent results modulo the existence of completely empty columns that are inputs for sapto (#158)income_tax will work if .dots.ATO is a non-data.table data.frame.model_income_tax:

This broke 3 unit tests because of the specific phrasing of some error messages.small_business_tax_offset() is now always positive, fixing the original misinterpretation of the legislation whereby negative business income resulted in a negative offset.*_inflator functions now return correct results for non-standard but supported financial years.inflator no longer fails when to_fy is length > 1 and unordered.mutate_ntile and mutate_weighted_ntile for adding quantile columnsage_pension,carer_paymentcarers_allowanceenergy_supplementfamily_tax_benefitnewstart_allowancepension_supplementrent_assistance the Commonwealth Rent Assistancemodel_rent_assistance as experimental function for modelling changes to rent assistance.youth_allowance() now available, though limitedcompare_avg_tax_rates: create a difference in average tax rates between multiple models and a baseline tax, by percentile.install_taxstats() as a convenient means to install the non-CRAN taxstats dependency.prohibit_vector_recycling() and friends return more informative error messages.income_tax, income_tax_sapto: the default value for fy.year is the current financial yearcpi_inflator, lf_inflator_fy, wage_inflator: if both from_fy and to_fy are missing, the default values become the previous and current financial years respectively. If only one of the two are missing, an error appears.income_tax is about twice as fast since 1.6.0.0: 1.5-2.0s down from 3.0-3.7s on the 100% population (13 million)inflator and cpi_inflator, lf_inflator_fy, and wage_inflator are now much faster when either from_fy or to_fy have more than 100,000 elements:set.seed(19952010)
