‘tools::deparseLatex()’ gains a ‘math’ argument, now used by the default ‘bibstyle’ to format ‘bibentry()’ fields with ‘$...$’ syntax via Rd \eqn markup.
‘requireNamespace(.., versionCheck = *)’ now shows an error and returns ‘FALSE’ when the package version check is not fulfilled, thanks to Iris Simmons and Trevor Davis's PR#18255.
