RELEASE NOTES:

core-libs/java.time:

    JDK-8339637: Support for Time Zone Database 2024b

      IANA Time Zone Database has been upgraded to 2024b. This version mainly includes changes to
      improve historical data for Mexico, Mongolia, and Portugal. It also changes one timestamp
      abbreviation, for the time zone 'MET'. Also Asia/Choibalsan is now an alias for
      Asia/Ulaanbaatar.
      
      The new tzdata changes also impact some legacy zone IDs. Mapping of EST/MST/HST in
      java.time.ZoneId.SHORT_IDS have changed from fixed offset zones to links to other existing
      time zones with 2024b. "EST" now links to "America/Panama", "HST" links to "Pacific/Honolulu"
      and "MST" links to "America/Phoenix".  Parsing of the short zone names "EST", "MST", and "HST"
      is not affected by this change. Further details are available at JDK-8340138

      IANA Time Zone Database has been upgraded to 2024b. This version mainly includes changes to
      improve historical data for Mexico, Mongolia, and Portugal. It also changes one timestamp
      abbreviation, for the time zone 'MET'. Also Asia/Choibalsan is now an alias for
      Asia/Ulaanbaatar.
      
      The new tzdata changes also impact some legacy time zone IDs. As per 2024b changes "EST" 
      links to "America/Panama", "HST" links to "Pacific/Honolulu" and "MST" links to
      "America/Phoenix". To maintain compatibility with the Java SE specification, the
      `java.time.ZoneId.SHORT_IDS` Map has not changed. Further details are available at JDK-8342331

core-libs/java.util.jar:

    JDK-8335912: New jar command option to not overwrite existing files

      The `jar` tool's extract operation has been enhanced to allow the `--keep-old-files` or the
      `-k` options to be used to preventing overwriting existing files.
      
      *Example Usages:*
      
      `jar xkf foo.jar`
      
      or
      
      `jar --extract --keep-old-files --file foo.jar`
      
      Either of these commands will extract the `foo.jar`, and if an entry with the same name
      already exist in the target directory, then the existing file will not be overwritten.
