BCMath:
. bcscale() can now also be used as getter to retrieve the current scale in use.
MBString:
. Support for full case-mapping and case-folding has been added. Unlike simple
case-mapping, full case-mapping may change the length of the string. For
example:
mb_strtoupper("Straße")
// Produces STRAßE on PHP 7.2
// Produces STRASSE on PHP 7.3
The different casing mapping and folding modes are available through
mb_convert_case():
. MB_CASE_LOWER (used by mb_strtolower)
. MB_CASE_UPPER (used by mb_strtolower)
. MB_CASE_TITLE
. MB_CASE_FOLD
. MB_CASE_LOWER_SIMPLE
. MB_CASE_UPPER_SIMPLE
. MB_CASE_TITLE_SIMPLE
. MB_CASE_FOLD_SIMPLE (used by case-insensitive operations)
Only unconditional, language agnostic full case-mapping is performed.
. Case-insensitive string operations now use case-folding instead of case-
mapping during comparisons. This means that more characters will be
considered (case insensitively) equal now.
. mb_convert_case() with MB_CASE_TITLE now performs title-case conversion
based on the Cased and CaseIgnorable derived Unicode properties. In
particular this also improves handling of quotes and apostophes.
. Data tables have been updated for Unicode 10.
. Mbstring now correctly supports strings larger than 2GB.
. Performance of the mbstring extension has been significantly improved
across the board. The largest improvements are in case conversion functions.
readline:
. Support for the completion_append_character and completion_suppress_append
options has been added to readline_info(). These options are only available
