60.2:
New API for direct-UTF-8 normalization.
- It also optionally records changes, for source-to-result index mapping and tracking of text metadata.
More convenient case mapping API (StringPiece→ByteSink).
ICU now handles ill-formed UTF-8 byte sequences as specified in the W3C Encoding Standard.
Bug fixes:
CLDR 32.0.1
- Change of some German AM/PM to English strings reverted; will be revisited.
- BGN transliterations restored.
The Script_Extensions property value for 5 CJK characters is wrong.
ICU4J DecimalFormat
- getGroupingSize() returns -1 instead of 0 in ICU60 if grouping is disabled
- setPositivePrefix also changes negative prefix
- unsets maxFrac when minFrac is set on a currency instance
DateFormat
- Urdu Islamic calendar eras
- Narrow format of noon time is used for abbreviated day period pattern letter 'b' and 'bb'
Conversion buffer overflow
Calendar buffer overrun
Windows C++: The header file "stringoptions.h" is not included in the the pre-built binary .zip file download.
Fix various typos and spelling mistakes.
Changes 60.1:
* Unicode 10.0: 8,518 new characters, including four new scripts, 7,494 new Han characters, and 56 new emoji characters.
- Properties newly supported in ICU: Emoji_Component, Regional_Indicator, Prepended_Concatenation_Mark
* CLDR 32:
- Data for several (mostly Asian) new languages, date formatting patterns using colloquial day period formats ("h:mm B" → “1:30 in the afternoon”), and many other data improvements.
- See the CLDR download page for other CLDR features and migration issues in CLDR 32.
* NumberFormatter, a new number formatting API: A long-overdue refresh of number formatting in ICU with a focus on usability, robustness, and performance. The 30+ settings in DecimalFormat are reduced to 8 in NumberFormatter; all NumberFormatter objects are thread-safe and immutable; and the code is efficient in both the client-side (constant locale) and server-side (variable locale) use cases.
- New users are encouraged to use the new API for number formatting. However, preexisting code can continue using the old API, which has been partially made into a wrapper over the new API.
- Documentation: in Java, see com.ibm.icu.number.NumberFormatter, and in C++, see i18n/unicode/numberformatter.h.
* New options for titlecasing:
- Sentence titlecasing and whole-string titlecasing without custom BreakIterator instances.
- The default index adjustment has been changed from "find first cased character" to "find first letter, number, or symbol"; a new option is available for selecting the previous adjustment behavior.
* Smaller data files for BreakIterator.
- Reverse rules no longer used: Easier updates, easier to conform to Unicode Standard.
- Old source rule files continue to work, reverse rules are ignored.
- Rule-based data files: 1.2MB→0.8MB.
ICU4C Specific Changes
* New API for direct-UTF-8 normalization.
- It also optionally records changes, for source-to-result index mapping and tracking of text metadata.
* More convenient case mapping API (StringPiece→ByteSink).
* ICU now handles ill-formed UTF-8 byte sequences as specified in the W3C Encoding Standard.
netbsd&linux do not have it (glibc had it, but removed in 2.26, and
was satisfied by locale.h always, if their release notes is to be believed)
this should cover BSDs other than netbsd, etc.
This was a glibc header, whereas locale.h is a POSIX one.
glibc went ahead and removed it in the new version.
change suggested by Thomas Orgis on tech-pkg but probably not applied
exactly.
* Emoji 5.0 data
* Includes bidi data files from Unicode 10 beta.
* Includes segmentation data files and rules from Unicode 10 beta and CLDR 31.0.1.
* Does not yet include the Emoji_Component property.
* Otherwise ICU 59 continues to use Unicode 9 data.
CLDR 31.0.1
* Including updates for emoji 5.0, for example local names for England, Scotland, and Wales.
* GMT and UTC are no longer unified, and CLDR provides distinct UTC display names, avoiding confusion with standard (winter) time in Britain.
* See the CLDR download page for other CLDR features and migration issues in CLDR v31.
New case mapping API (C++ & Java classes CaseMap) supports styled text.
Common Changes
* CLDR 30.0.3
* Time zone database version 2016j
* ICU SVN repository structure change. See the note on the Source Code Access page for more information.
ICU4C Fixes
* 12815 uspoof_getSkeleton sets backwards-incompatible illegal argument exception
* 12822 digitlist.cpp won't compile on msvc under Node.js
* 12825 uspoof_check goes into an "infinite loop" when U+30FB is in an input string
* 12832 GreekUpper::toUpper skips the final character on a non-terminated UTF-8 string
* 12849 u_strToTitle returns incorrect length if destination is NULL
* 12868 uprv_convertToPosix() Windows bug
* Fix regression with upstream patch,

Common Changes
CLDR 30.0.2: For details of the many changes in CLDR, see CLDR 30. Some things to note:
For some combinations of numbering system (arab, arabext, latn) and/or locale (ar, fa, he), there were changes to the bidirectional control characters used with certain symbols (percent, minus, plus), and changes to number patterns (currency and/or percent, including addition of bidirectional control characters in some cases).
New in this release, the bidirectional controls used for such purposes include U+061C ARABIC LETTER MARK (ALM), which requires use of the bidirectional algorithm from Unicode 6.3 or later.
The time separator for Norwegian locales (nb, nn) was changed to be ':' throughout.
Unicode 9.0: Version 9.0 adds exactly 7,500 characters, for a total of 128,172 characters. These additions include six new scripts, 19 symbols for the new 4K TV standard, and 72 new emoji characters.
Draft Emoji 4.0 data
Emoji updates for word & line breaking. (#12664 & Unicode 9 update #12526)

Release Overview
The features for this release include support of CLDR 28 and Unicode 8.0.
For more details, including migration issues, see below.
Common Changes
CLDR 28: For details of the many changes in CLDR, see CLDR 28.
Unicode data updated to Unicode 8.0: 41 new emoji characters, 5,771 new ideographs for Chinese/Japanese/Korean, 6 new scripts, improved character properties data, etc.
ICU data size reduced by about 7.2% (1.8MB) via sharing string values across resource bundles. [#11537]
DateIntervalFormat now handles intervals with seconds, and sets FieldPosition more consistently. [#11706, #11726]
DateFormat::createInstanceForSkeleton() caches DateFormat patterns rather than DateTimePatternGenerator instances, for better performance (for cache hits) and lower heap memory consumption. [#11780]
StringSearch (based on collation) defaults to matches on normalization boundaries rather than grapheme cluster boundaries, which yields more matches on Indic text. [#11750]
RuleBasedNumberFormat (spelled-out numbers) now handles rounding (Java only), infinity, NaN. [#11653, #11760, #8223]
Most of the old Normalizer/unorm.h had been replaced by (and reimplemented via) Normalizer2, and is now deprecated. [#7303]
COLON has been withdrawn as a date pattern character corresponding to the date field [UDAT_]TIME_SEPARATOR_FIELD; there is currently no pattern character corresponding to that field. [#11773]
Support for locale key "cf" to specify currency format style, and interaction with NumberFormat values for UNumberFormatStyle: [#11787]
For NumberFormat style UNUM_CURRENCY / CURRENCYSTYLE, the default is "standard" currency style (typically using minus sign for negative numbers), but the new locale key "cf" may be used with values "standard" or "account" to specify currency format style ("account" indicates accounting style, often using parentheses for negative numbers).
For other NumberFormat styles, the locale key "cf" is ignored (they override the locale preference):
UNUM_CURRENCY_ISO / ISOCURRENCYSTYLE
UNUM_CURRENCY_PLURAL / PLURALCURRENCYSTYLE
UNUM_CURRENCY_ACCOUNTING / ACCOUNTINGCURRENCYSTYLE
UNUM_CASH_CURRENCY / CASHCURRENCYSTYLE
A new NumberFormat style is availble to explicitly specify standard style, ignoring the the locale key "cf"
UNUM_CURRENCY_STANDARD / STANDARDCURRENCYSTYLE
ICU4C Specific Changes
C API support for CompactDecimalFormat via UNumberFormatStyle additions: UNUM_DECIMAL_COMPACT_SHORT, UNUM_DECIMAL_COMPACT_LONG [#11693]
Larger UnicodeString object stores more characters inside the object without heap allocation; the UnicodeString object size is now build-time-configurable. [#11551]
On 64-bit machines, increase from object size 40 bytes with 15 internal UChars to a new default of 64 bytes with 27 UChars.
Some C++ classes now have swap() and moveFrom() methods, and support C++11 move semantics on compilers that support them. [#10086]
UnicodeString, LocalPointer, LocalArray
DecimalFormat code refactored to fix bugs, improve maintainability, and improve performance. [#10458]
New FilteredBreakIterator suppresses certain segment boundaries. For example, it can suppress the sentence boundary in the middle of "Mr. Smith". [#11248]
The internal, shared cache has been changed from unbounded to bounded. [#11767]
For [U]BreakIterator with type UBRK_SENTENCE, the locale key "ss" can now be used with value "standard" to specify that standard sentence break suppression data should be used, or with value "none" to indicate that no break suppression data should be used (the default). [#11770]
Collator: first-time startup time improved 20% due to precalculated unsafe-backward table [#11886]
A number of memory leaks and buffer overruns have been fixed based on static code analysis, mostly in data build tools
The features for this release include support of CLDR 27 (with a major cleanup of region locales, among many other improvements), formatting for scientific notation ("1.2 × 10³"), an update to Unicode 7.0 data for spoof-checking, narrow AM/PM markers ("7:45p"), and various performance enhancements. For C/C++, there are new methods for flexible dates ("Nov 10", or "Sept 2015"), named capture groups for regular expressions, formatting of compound units ("3.5 meters per second"), new C wrappers, and independent timezone resource loading. ICU4J has been improved and tested for using ICU4C data and for running on Android.
Data from the CLDR 25 release: Many bug fixes
Time zone data: 2014b, including post CLDR 25 time zone data update to CLDR.
U+20BD Ruble Sign added (from Unicode 7.0, otherwise ICU 53 still uses Unicode 6.3)
MeasureFormat API for new units in CLDR 24
Hoisted setContext/getContext from SimpleDateFormat to DateFormat, implement context-sensitive capitalization of relative dates
Added setContext/getContext methods to NumberFormat (and unum_setContext/unum_getContext for UNumberFormat), implement context-sensitive number formatting (for RBNF spellout)
Improved lenient date parsing consistency between ICU4C and ICU4J, add finer-grained control of date parsing leniency
Fixed numeric rounding in TimeUnitFormat
Fixes to Unicode 6.3 bidirectional algorithm implementations to behave exactly like reference implementations
Improved UTF-16 charset detection
Collation code re-implemented
Many bugs fixed, some enhancements implemented (link for ticket query)
Passes full UCA conformance tests now
Updated to UCA 6.3/CLDR 24 root collation
Performance: C++ UTF-8 and Java string comparisons significantly faster (very small reduction for C++ UTF-16)
Collation data size (uncompressed) reduced from 4.48MB (ICU 52) to 2.62MB
New data format, removed empty files, fixed genrb bug
More APIs function when collation rule strings have been omitted from the data files (e.g., getTailoredSet())
Java Collator.compare(Object, Object) now works with CharSequence, not just String
Java Collator base class (does not apply to RuleBasedCollator instances): getters for strength, decomposition mode, and locales return hardcoded default values; their setters do nothing
Rule syntax and semantics tightened and improved, matching LDML 25 Collation Rule Syntax
In particular, rule chains now must start with a reset.
Setting of variableTop deprecated, and not supported in rule syntax any more
Replaced by the new maxVariable setting; see LDML 25 Collation Settings
Accounting format supported in NumberFormat
RelativeDateTimeFormatter class for formatting relative times such as "3 weeks ago" or "next Tuesday."
Updated Spoof Checker for Unicode Security Standard version 6.3.
