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)
UBiDiTransform/BidiTransform API for convenient transformation of text between different Bidi layouts. (#11679)
MeasureFormat API for measurement unit display names. (#12029)
Most COUNT and LIMIT enum constants have been deprecated. (#12420)
SpoofChecker: Handling of "whole script confusables" has been removed from ICU, in accordance with its removal from UTS #39 Version 9.0.0 and the removal of the corresponding Unicode data file. (#12549)
Greek uppercasing ("el" locale ID) removes most diacritics. (#5456)
More robust locale data loading across ICU implementation code.
Reduced heap memory usage in DateTimePatternGenerator. (#11782)
ICU4C Specific Changes
The layout engine code has been removed; the ParagraphLayout is not deprecated and remains (and must now be built on top of HarfBuzz). See http://userguide.icu-project.org/layoutengine (#12708)

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.
Unicode 6.3: New bidi control codes, new Bidi_Class property values, two new bidi "bracket" properties; for other property value changes see the UAX 44 summary.
The bidi algorithm implementation has also been updated to support the new properties and to match the updated algorithm in the Unicode 6.3 version of UAX 9.
Note: ICU 52 still uses collation root data based on Unicode Collation Algorithm 6.2 (UCA 6.2). (However, ICU 52 does use CLDR 24 collation tailoring data.)
CLDR 24: Improved coverage for top 70+ languages, fractional plural rules and forms, many new measurement units, major simplification of collation rule syntax, preliminary version of European Ordering Rules, new relative fields such as “last Sunday” and “now”, and much more.
Time zone data: 2013g.
Support new variants of Islamic calendar:
"islamic-umalqura": Umm al-Qura.
"islamic-tbla": Tabular (fixed intercalary years), with astronomical epoch.
Made Calendar getDayOfWeekType behave as documented.
New API for converting between Windows time zone ID and IANA tz database ID.
Technology Preview: New API for more granular control of DateFormat parse leniency.
DateTimePatternGenerator:
Support recently-added time zone pattern characters O, X, x and updated support for V, Z.
Support newly-defined skeleton character ‘J’ to generate preferred hour cycle without any day period indicator (such as AM/PM for h).
Implement support for plurals that depend on displayed fractional values.
MessageFormat and currency formatting etc. select appropriate plural forms for values with decimal digits (after the decimal point).
Segmentation:
Add dictionary-based word & line break for Lao.
As "DSO_LIBDIR" is now always set (and must be always set because of all
the changes that refer to it) we cannot use it to check for the Cygwin
case anymore. Instead check whether "OPSYS" is (not) equal to "Cygwin".
Bug fixes:
* fix for enumset.h not being installed on Windows
* zOS pkgdata fix
* Test fixes
* Region enumeration fix
* make stable sort faster
* host failures for DateFormatTest
* LayoutEngine security patches (see above)
* ubrk fix for word_POSIX infinite loop
* fix memory leak/crash in LayoutEngine
* fix header guard typo in layout/TibetanReordering.h
