canadacovid 0.3.3

• Added a NEWS.md file to track changes to the package.
• Fixed a bug where the last_updated variable was being parsed incorrectly in get_reports(), get_summary(), get_subregion_vaccination_data() and get_vaccine_age_groups().
• The get_provinces() function now returns updated_at in the CST timezone in order to be consistent with the other tables. To do this, the lubridate package has been added under Imports for the with_tz() function.
• The API now returns two additional variables change_boosters_2 and total_boosters_2. Adjusted the tests (test-reports, test-summary and test-vaccination) to account for the new variables.
