Colossus 0.9

• Added a NEWS.md file to track changes to the package.

Colossus 1.0.0

• Initial submission
• C++ code modified to not apply OpenMP code if OpenMP isn’t detected, to resolve MacOS installation failures

Colossus 1.0.1

• Configuration improved to detect compiler information
• Linux configuration depends on the system wide c++ default and the compiler used to compile R
• OpenMP support is not used if the c++ default or the R compiler is clang

Colossus 1.0.2

• utility checks updated to check that keep_constant is 0/1 values
• code will fail if keep_constant is not integer valued and 0/1, with explanation of why

Colossus 1.0.3

• configuration script libraries moved from Suggested: to Imports:
• configuration script functions moved to non-exported functions in Colossus, circumvents note about imported libraries not being used and may be later used to provide the user with a function that informs them of why OpenMP is/isn’t supported

Colossus 1.0.4

• utility checks updated to check term numbers and subterm types in R side
• code will fail if term numbers are not integers, term numbers are missing, or subterm types are

Colossus 1.0.5

• compilation flags changed to macros

Colossus 1.1.0

• Default Makevars is now fully portable
• By default only windows uses OpenMP now
• The GitHub version will include instructions on activating configuration to use OpenMP on gcc Linux

Colossus 1.1.1

• ggplot2 no longer required, now optional
• additional testing added for coverage
• default Makevars added via bash script

Colossus 1.1.2

• Log-likelihood bound functionality added
• subject to usual convergence issues, manual search option

Colossus 1.1.3

• Cox regression now removes rows that end before first event and start after last event
• Cox regression now sets constant rows to be constant, helps with aliasing
• Tests now use sink() to avoid printing as much excessive output to console. Tests now consolidated further.

Colossus 1.1.4.1

• Cox plotting functions now return the tables used for plots (only last plot table returned)
• Plotting vignette updated to include more details and plots
• survival package listed as suggested for plotting vignette

Colossus 1.1.4.2

• R errors and warnings sent to stop() and warning(). C++ errors and warnings still controlled by verbosity argument
• ggsave defaults to width/height = 7
• Updates started to fix possible OpenMP issues with fedora 36 running clang 18
• Unable to have debug printing as an option and cover the c++ files with testing, but still have test output be readable. debug output removed.
