Liberica JDK 26.0.2+13: Release Notes$$$Published: July 21; 2026$$$$$$1. Version information$$$This document provides information about Liberica JDK 26.0.2 release. The full version string for this update release is 26.0.2+13. The version number is 26.$$$$$$Liberica JDK 26 is distributed as .apk; .rpm; .zip; .deb; .pkg; and .tar.gz packages. Please select the most appropriate for your purposes.$$$$$$2. What’s New$$$This release contains the following updates and new features.$$$$$$Notable Changes$$$This is the list of the notable issues fixed in this release.$$$$$$Issue IDt$$$JDK-8347938$$$$$$Summary: Add Support for the Latest ML-KEM and ML-DSA Private Key Encodings$$$$$$Description: The JDK now encodes ML-KEM and ML-DSA private keys in PKCS #8 format using the DER-encoded ASN.1 CHOICE formats defined in Section 6; Private Key Format of RFC 9935 and Section 6; Private Key Format of RFC 9881. Two new security properties; jdk.mlkem.pkcs8.encoding and jdk.mldsa.pkcs8.encoding; control the encoding used when generating new keys with a KeyPairGenerator or when translating keys with a KeyFactory. Valid values are seed; expandedKey; and both (case-insensitive). If a system property of the same name is also specified; it supersedes the security property value. All three formats are supported when decoding previously encoded private keys with a KeyFactory. The default encoding for newly generated ML-KEM and ML-DSA private keys is seed. Applications that require a particular private-key encoding can configure the relevant security property or equivalent system property.$$$$$$JDK-8372351$$$$$$Summary: Added WISeKey Global GB and GC Root CA Certificates$$$$$$Description: wisekeyglobalrootgbca and wisekeyglobalrootgcca root certificates have been added to the cacerts truststore.$$$$$$JDK-8381670$$$$$$Summary: Revert the changes to GZIPInputStream related to InputStream.available() usage$$$$$$Description: Reverted the changes to java.util.zip.GZIPInputStream that were done in JDK-7036144 (CSR JDK-8327489). The implementation of GZIPInputStream is now reverted to using InputStream.available() for deciding whether or not to read past a GZIP stream trailer.$$$$$$JDK-8382740$$$$$$Summary: JFR Event jdk.OldObjectSample Disabled for Generational ZGC$$$$$$Description: The JFR event jdk.OldObjectSample is disabled when using generational ZGC. The combination results in unacceptable performance overhead because the implementation relies on weak handles that; in generational ZGC; are processed only in the old generation.$$$$$$JDK-8385665$$$$$$Summary: Address possible oversized errors in Math.pow$$$$$$Description: The FDLIBM 5.3 algorithm for pow; as uncorrected before JDK-8326547; for some inputs returned 600+ ulp errors rather than < 1 ulp errors as specified. In cases where Math.pow delegates to StrictMath.pow; it now uses the corrected algorithm even on platform versions where using the uncorrected original algorithm is specified.$$$$$$Discontinued OS support$$$Note that Liberica JDK 26.0.2 is not available for and cannot be run on the following operating systems:$$$$$$Windows x86 (32-bit)$$$$$$macOS 10.x$$$$$$IANA TZ Data version$$$This release of Liberica JDK 26.0.2 comes with the 2026b version of the in-tree copy of the IANA timezone database. The following are the key features of this version.$$$$$$Briefly$$$British Columbia moved to permanent -07 on 2026-03-09.$$$$$$Some more overflow bugs have been fixed in zic.$$$$$$Changes to future timestamps$$$British Columbia’s 2026-03-08 spring forward was its last foreseeable clock change; as it moved to permanent -07 thereafter. (Thanks to Arthur David Olson.) Although the change to permanent -07 legally took place on 2026-03-09; temporarily model the change to occur on 2026-11-01 at 02:00 instead. This works around a limitation in CLDR v48.2 (2026-03-17). This temporary hack is planned to be removed after CLDR is fixed.$$$$$$Changes to code$$$zic no longer mishandles a last transition to a new time type.$$$$$$zic no longer overflows a buffer when generatin
