Summary by CodeRabbit

  • New Features
    • Added a guide for migrating Umi transactions from V0 to V1, with setup requirements, examples, limitations, and troubleshooting.
    • Expanded transaction documentation with V1 support, including its larger size limit and compute configuration options.
  • Documentation
    • Updated guides for transaction serialization, compute units, priority fees, and address lookup tables to clarify when to use V0 or V1.
    • Added version requirements and wallet compatibility notes for V1 transactions.
    • Added direct links to royalty inheritance sections in Japanese, Korean, and Chinese Bubblegum guides.

Walkthrough

The PR updates Umi and Solana documentation for V1 transactions, including migration guidance, configuration examples, and compatibility limits. It also adds a shared section anchor to three translated Bubblegum V2 pages.

Changes

Transaction V1 documentation

Layer / File(s) Summary
Guide discovery and prerequisites
src/components/products/umi/index.js, src/pages/en/dev-tools/umi/getting-started/index.md, src/pages/en/dev-tools/umi/guides/index.md
The Umi navigation and guide index link to the migration guide. The getting-started page specifies the Web3.js version for V1 support.
V0-to-V1 migration steps
src/pages/en/dev-tools/umi/guides/migrate-to-transaction-v1.md
A new guide documents V1 prerequisites, configuration, application defaults, direct creation, integration updates, and migration errors.
Umi transaction and Web3.js references
src/pages/en/dev-tools/umi/transactions.md, src/pages/en/dev-tools/umi/web3js-differences-and-adapters.md
The references describe V1 transaction creation, configuration, examples, and Web3.js compatibility.
Compute limits and priority fees
src/pages/en/dev-tools/umi/guides/optimal-transactions-with-compute-units-and-priority-fees.md, src/pages/en/dev-tools/umi/toolbox/priority-fees-and-compute-managment.md
The guides show V1 compute and fee configuration through setTransactionConfig() and retain V0 examples using Compute Budget instructions.
Serialization and lookup-table guidance
src/pages/en/dev-tools/umi/guides/serializing-and-deserializing-transactions.md, src/pages/en/dev-tools/umi/toolbox/address-lookup-table.md
Serialization examples select V1. The lookup-table guide specifies V0 for builders that use Address Lookup Tables.
Solana transaction formats
src/components/products/guides/index.js, src/pages/en/solana/solana-transaction-fundamentals.md
The fundamentals guide describes Legacy, V0, and V1 formats, size limits, and lookup-table support. Its navigation date is updated.

Bubblegum V2 translated-page anchors

Layer / File(s) Summary
Royalty-inheritance section anchors
src/pages/ja/smart-contracts/bubblegum-v2/mint-cnfts.md, src/pages/ko/smart-contracts/bubblegum-v2/mint-cnfts.md, src/pages/zh/smart-contracts/bubblegum-v2/mint-cnfts.md
The Japanese, Korean, and Chinese pages add the same anchor identifier to the royalty-inheritance heading.

These pages document V1 transactions only in English. Japanese, Korean, and Chinese readers still see outdated V0-only guidance, and the new migration guide has no translated version at all. The compute-unit example can set a limit above the V1 maximum. A few prerequisite and wording details are also inaccurate. Add the translations and fix the example before merging, or explicitly accept the translation gap for later.

Inline comments:
In `@src/pages/en/dev-tools/umi/guides/migrate-to-transaction-v1.md`:
- Around line 1-4: Add Japanese, Korean, and Chinese counterparts for the
“Migrating from V0 to V1 Transactions” guide. Mirror the English guide’s
sections, examples, and frontmatter fields in each locale, translating the
fields and prose as required by the locale conventions.

In
`@src/pages/en/dev-tools/umi/guides/optimal-transactions-with-compute-units-and-priority-fees.md`:
- Line 376: Validate the buffered value from getRequiredCU against the
documented V1 maximum before assigning computeUnitLimit; if it exceeds the
maximum, report that the transaction cannot fit within the V1 limit.
- Line 24: Add a Quick Start section to the guide, using jump links to its main
steps. Place it near the beginning after the Summary, and ensure each link
targets the corresponding section heading.
- Line 24: Move the introductory sentence below the Summary section so Summary
is the first body section on both pages:
src/pages/en/dev-tools/umi/guides/optimal-transactions-with-compute-units-and-priority-fees.md
(line 24) and
src/pages/en/dev-tools/umi/toolbox/priority-fees-and-compute-managment.md (line
23). Keep each page’s existing introduction and Summary content.
- Line 26: Update the translated `ja`, `ko`, and `zh` copies of
`optimal-transactions-with-compute-units-and-priority-fees.md` to mirror the
English guide’s V1 estimation flow, examples, structure, and frontmatter. Also
update each locale’s `priority-fees-and-compute-managment.md` to mirror the
English V1/V0 configuration guidance and structure. Affected sites:
`src/pages/en/dev-tools/umi/guides/optimal-transactions-with-compute-units-and-priority-fees.md`
lines 26-26 and
`src/pages/en/dev-tools/umi/toolbox/priority-fees-and-compute-managment.md`
lines 21-21 identify the source content; make the corresponding translation
changes in all three locales.

In
`@src/pages/en/dev-tools/umi/guides/serializing-and-deserializing-transactions.md`:
- Line 125: Update the prerequisites callout for the V1 transaction examples to
include `@solana/web3.js` 1.99.0 or later alongside the existing Umi and wallet
requirements.

In `@src/pages/en/dev-tools/umi/transactions.md`:
- Line 252: Update the V1 transaction guidance near the migration link to say
that Umi transaction builders reject Compute Budget instructions, while
low-level umi.transactions.create() does not apply that builder check;
distinguish this Umi behavior from runtime behavior, which ignores Compute
Budget instructions for V1 configuration.
- Line 26: In src/pages/en/dev-tools/umi/transactions.md at lines 26-26, move
the existing Summary block directly after the frontmatter, before the
introductory paragraph and component list. In
src/pages/en/dev-tools/umi/web3js-differences-and-adapters.md at lines 223-226,
add a Summary block directly after the frontmatter with 1–2 declarative
sentences followed by 3–4 bullets.

In `@src/pages/en/dev-tools/umi/web3js-differences-and-adapters.md`:
- Around line 232-234: Move the Web3.js V1 compatibility caveat from the callout
into a `## Notes` section in the page, preserving its existing information about
deserialization, serialization, Umi’s adapter serializer, and V0 examples.

In `@src/pages/en/solana/solana-transaction-fundamentals.md`:
- Around line 200-203: Update the Japanese, Korean, and Chinese counterparts of
the solana-transaction-fundamentals page to mirror the English page’s V1
subsection, including translated limits and compatibility guidance; revise their
transaction-format and maximum-size information to match V1 support while
preserving each page’s locale and existing structure.
- Line 195: Add a direct declarative answer sentence immediately after each
version heading, including “V0 Transactions,” before the existing bullet
fragments; preserve the remaining subsection content.
