[NEW FUNCTIONS] #137: date-time formatting/parsing:
- stri_timezone_list() - lists all known time zone identifiers
- stri_timezone_set(), stri_timezone_get() - manage current default time zone
- stri_timezone_info() - basic information on a given time zone
- stri_datetime_symbols() - localizable date-time formatting data
- stri_datetime_fstr() - convert a strptime-like format string to an ICU date/time format string
- stri_datetime_format() - convert date/time to string
- stri_datetime_parse() - convert string to date/time object
- stri_datetime_create() - construct date-time objects from numeric representations
- stri_datetime_now() - return current date-time
- stri_datetime_fields() - get values for date-time fields
- stri_datetime_add() - add specific number of date-time units to a date-time object
[BUGFIX] #168: Build now fails if icudt is not available.
[BACKWARD INCOMPABILITY] The second argument to stri_pad_*() has been renamed width.
[GENERAL] #69: stringi is now bundled with ICU4C 55.1.
[NEW FUNCTIONS] stri_extract_*_boundaries() extract text between text boundaries.
[NEW FUNCTION] #46: stri_trans_char() is a stringi-flavoured chartr() equivalent.
[NEW FUNCTION] #8: stri_width() approximates the width of a string in a more Unicodish fashion than nchar(..., "width")
[NEW FEATURE] #149: stri_pad() and stri_wrap() now by default bases on code point widths instead of the number of code points. Moreover, the default behavior of stri_wrap() is now such that it does not get rid of non-breaking, zero width, etc. spaces
[NEW FEATURE] #133: stri_wrap() silently allows for width <= 0 (for compatibility with strwrap()).
[NEW FEATURE] #139: stri_wrap() gained a new argument: whitespace_only.
[GENERAL] #144: Performance improvements in handling ASCII strings (these affect stri_sub(), stri_locate() and other string index-based operations)
[GENERAL] #143: Searching for short fixed patterns (stri_*_fixed()) now relies on the current libC's implementation of strchr() and strstr(). This is very fast e.g. on glibc utilizing the SSE2/3/4 instruction set.
[GENERAL] #141: a local copy of icudt*.zip may be used on package install; see the INSTALL file for more information.
[GENERAL] #165: the ./configure option --disable-icu-bundle forces the use of system ICU when building the package.
[BUGFIX] locale specifiers are now normalized in a more intelligent way: e.g. @calendar=gregorian expands to DEFAULT_LOCALE@calendar=gregorian.
[BUGFIX] #134: stri_extract_all_words() did not accept simplify=NA.
[BUGFIX] #132: incorrect behavior in stri_locate_regex() for matches of zero lengths
[BUGFIX] stringr/#73: stri_wrap() returned CHARSXP instead of STRSXP on empty string input with simplify=FALSE argument.
[BUGFIX] #164: libicu-dev usage used to fail on Ubuntu.
[BUGFIX] #135: C++11 is now used by default (see the INSTALL file, however) to build stringi from sources. This is because ICU4C uses the long long type which is not part of the C++98 standard.
[BUGFIX] #154: Dates and other objects with a custom class attribute were not coerced to the character type correctly.
[BUGFIX] Force ICU u_init() call on stringi dynlib load.
[BUGFIX] #157: many overfull hboxes in the package PDF manual has been corrected.
