RELEASE NOTES, BY COMPONENT:

core-libs/java.util:i18n: JDK-8238914: Localized Time Zone Name Inconsistency Between English and Other Locales English time zone names provided by the CLDR locale provider are now correctly synthesized following the CLDR spec, rather than substituted from the COMPAT provider. For example, SHORT style names are no longer synthesized abbreviations of LONG style names, but instead produce GMT offset formats. core-libs/javax.naming: JDK-8258824: LDAP Channel Binding Support for Java GSS/Kerberos A new JNDI environment property `“com.sun.jndi.ldap.tls.cbtype”` has been added to enable TLS Channel Binding data in LDAP authentication over SSL/TLS protocol to the Windows AD server. Possible value is `“tls-server-end-point”` - Channel Binding data is created on the base of the TLS server certificate. See the module description of the `java.naming` module. security-libs/java.security: JDK-8236730: Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default Weak named curves are disabled by default by adding them to the following `disabledAlgorithms` security properties: `jdk.tls.disabledAlgorithms`, `jdk.certpath.disabledAlgorithms`, and `jdk.jar.disabledAlgorithms`. The named curves are listed below. With 47 weak named curves to be disabled, adding individual named curves to each `disabledAlgorithms` property would be overwhelming. To relieve this, a new security property, `jdk.disabled.namedCurves`, is implemented that can list the named curves common to all of the `disabledAlgorithms` properties. To use the new property in the `disabledAlgorithms` properties, precede the full property name with the keyword `include`. Users can still add individual named curves to `disabledAlgorithms` properties separate from this new property. No other properties can be included in the `disabledAlgorithms` properties. To restore the named curves, remove the `include jdk.disabled.namedCurves` either from specific or from all `disabledAlgorithms` security properties. To restore one or more curves, remove the specific named curve(s) from the `jdk.disabled.namedCurves` property. Curves that are disabled through `jdk.disabled.namedCurves` include the following: secp112r1, secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62 c2tnb239v1, X9.62 c2tnb239v2, X9.62 c2tnb239v3, X9.62 c2tnb359v1, X9.62 c2tnb431r1, X9.62 prime192v2, X9.62 prime192v3, X9.62 prime239v1, X9.62 prime239v2, X9.62 prime239v3, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1 Curves that remain enabled are: secp256r1, secp384r1, secp521r1, X25519, X448 core-libs/java.time: JDK-8254679: US/Pacific-New Zone Name Removed as Part of tzdata2020b Following the JDK's update to tzdata2020b, the long-obsolete files named `pacificnew` and `systemv` have been removed. As a result, the "US/Pacific-New" Zone name declared in the `pacificnew` data file is no longer available for use. Information regarding this update can be viewed at https://mm.icann.org/pipermail/tz-announce/2020-October/000059.html core-svc/java.lang.management: JDK-8236876: OperatingSystemMXBean Methods Inside a Container Return Container Specific Data When executing in a container, or other virtualized operating environment, the following `OperatingSystemMXBean` methods in this release return container specific information, if available. Otherwise, they return host specific data: - `getFreePhysicalMemorySize()` - `getTotalPhysicalMemorySize()` - `getFreeSwapSpaceSize()` - `getTotalSwapSpaceSize()` - `getSystemCpuLoad()`
