This significant evolution involves a critical namespace transition from hashgraph to <code>hiero<\/code> or <code>hiero-ledger<\/code>, affecting project dependencies and SDK imports. This shift emphasizes greater transparency, collaboration, and open-source innovation, and developers are encouraged to update their dependencies accordingly to stay aligned.<\/p>\n<h4 class=\"color-ultraviolet\">Why the Migration from Hedera to Hiero?<\/h4>\n<p>In September 2024, Hedera took the strategic step of open sourcing its entire codebase, <a href=\"https:\/\/hedera.com\/blog\/introducing-hiero-the-foundation-of-the-future\">creating Hiero<\/a>\u2014an open, vendor-neutral platform hosted by the Linux Foundation\u2019s LF Decentralized Trust. Hiero inherits Hedera\u2019s robust technology and expands its reach by inviting community-driven collaboration, governance, and continuous innovation.<\/p>\n<p>Hiero embraces an entirely open source and community-governed model, which makes it vendor-neutral, more transparent, inclusive, and fosters broader ecosystem growth.<\/p>\n<h4 class=\"color-ultraviolet\">What Does This Mean for Developers?<\/h4>\n<p>Developers using Hedera SDKs in Java, JavaScript, or Rust projects must update their project configurations, including package identifiers and dependencies, from the previous hashgraph namespace to the new <code>hiero<\/code> or <code>hiero-ledger<\/code> namespaces.<\/p>\n<p>Two primary migration strategies are being used, depending on the SDK:<\/p>\n<h4 class=\"color-ultraviolet\">Single-Step Cutover<\/h4>\n<p>This involves a complete switch from the old namespace to the new one in a single, clearly defined release. After this release, new SDK updates will only be available under the new namespace. Older versions will remain accessible under the original <code>hashgraph<\/code> namespace but will no longer receive updates or new features.<\/p>\n<p><strong>Java SDK<\/strong><\/p>\n<ul>\n<li>The Java SDK will transition to the new namespace starting from version <code>2.80.0<\/code> (approximately in 9 months).<\/li>\n<li>This change involves updating your build tools (e.g., Maven or Gradle configurations) to reflect the new groupId (<code>org.hiero<\/code>) and artifactId (<code>hiero-sdk<\/code>).<\/li>\n<li>Documentation and warnings about this upcoming transition will be clearly communicated leading up to the cutover.<\/li>\n<\/ul>\n<p>\u2192 <a href=\"https:\/\/github.com\/hiero-ledger\/hiero-sdk-java\/blob\/main\/HIERO_MIGRATION.md\" target=\"_blank\"><strong>Migration guidelines<\/strong><\/a> for Java SDK<\/p>\n<h4 class=\"color-ultraviolet\">Dual Publishing<\/h4>\n<p>Dual publishing involves simultaneously releasing SDK updates under both the old (<code>hashgraph<\/code>) and new (<code>hiero<\/code> or <code>hiero-ledger<\/code>) namespaces for a specific transition period (6 months). After the dual publishing period, updates will only appear under the new namespace. This approach allows developers time to migrate their dependencies gradually.<\/p>\n<p><strong>JavaScript SDK<\/strong><\/p>\n<ul>\n<li>The dual publishing process will begin from <code>v2.70.0<\/code> to <code>v2.82.0<\/code> (6 months).<\/li>\n<li>Starting from version <code>2.83.0<\/code>, updates will exclusively appear under <code>@hiero-ledger<\/code>.<\/li>\n<\/ul>\n<p>\u2192 <a href=\"https:\/\/github.com\/hiero-ledger\/hiero-sdk-js\/blob\/main\/manual\/migration_hiero.md\" target=\"_blank\"><strong>Migration guidelines<\/strong><\/a> for JavaScript SDK<\/p>\n<p><strong>Rust SDK<\/strong><\/p>\n<ul>\n<li>The dual publishing process will begin from <code>v0.38.0<\/code> to <code>v0.50.0<\/code> (6 months).<\/li>\n<li>Starting from version <code>v0.51.0<\/code>, updates will exclusively appear under <code>hiero<\/code>.<\/li>\n<\/ul>\n<p>\u2192 <a href=\"https:\/\/github.com\/hiero-ledger\/hiero-sdk-rust\/blob\/main\/MIGRATION.md\" target=\"_blank\"><strong>Migration guidelines<\/strong><\/a> for Rust SDK<\/p>\n<h4 class=\"color-ultraviolet\">Resources and Support<\/h4>\n<ul>\n<li><a href=\"https:\/\/www.lfdecentralizedtrust.org\/blog\/hiero-advancing-decentralized-trust-through-open-source-innovation\" target=\"_blank\"><strong>Introduction to Hiero<\/strong><\/a>: Learn more about Hiero\u2019s vision and roadmap.<\/li>\n<li><a href=\"https:\/\/discord.com\/invite\/BCSKp4MKJm\" target=\"_blank\"><strong>Hiero at LF Decentralized Trust Discord<\/strong><\/a>: For direct community support and discussions.<\/li>\n<li><a href=\"https:\/\/github.com\/hiero-ledger\" target=\"_blank\"><strong>Hiero GitHub<\/strong><\/a>: Explore and contribute directly to Hiero projects.<\/li>\n<li><a href=\"https:\/\/github.com\/hiero-ledger\/sdk-collaboration-hub\" target=\"_blank\"><strong>SDK Collaboration Hub<\/strong><\/a>: Join broader community discussions, standardization initiatives, and efforts such as the newly developed<a href=\"https:\/\/github.com\/hiero-ledger\/hiero-sdk-python\" target=\"_blank\"> Python SDK<\/a>.<\/li>\n<\/ul>\n<h4 class=\"color-ultraviolet\">Conclusion<\/h4>\n<p>This namespace migration is essential for the long-term sustainability and community-centric governance of Hiero.
