1. Cargo.toml:1

• Draft comment:
  Workspace Cargo.toml bump and dependency versions look consistent. Note the use of Hyper 1.5.1 – double-check that this version is intentional, as most projects use Hyper 0.14.x.

  Workspace dependencies are pinned; versions such as tracing "0.1" and others appear deliberate—just verify they meet your compatibility requirements.

3. crates/cli/Cargo.toml:1

  CLI Cargo.toml correctly uses workspace dependencies; the package version matches the bump to 2.0.2 and README path is valid.

Greptile Overview

Greptile Summary

This PR performs a version bump to release 2.0.2, which includes a hotfix for v0 transactions with address lookup tables that was previously merged in PR #297.

Context

The actual bug fix was implemented in the previous commit (36970d8, PR #297), which removed a workaround that was converting v0 messages to legacy messages when calling get_fee_for_message. The workaround was originally added to handle an agave validator serialization issue (referenced in anza-xyz/agave#7719). Since that upstream issue has been resolved, the workaround was removed, allowing v0 transactions to be processed directly without conversion.

What Changed in This PR

This release PR updates version numbers across all workspace packages from 2.0.1 to 2.0.2:

• Root workspace version in Cargo.toml
• kora-cli package version and its dependency on kora-lib
• kora-lib package version
• Lock file updates for all three packages (kora-cli, kora-lib, tests)
• CHANGELOG.md entry documenting the hotfix

Version Consistency

All version references have been properly synchronized:

• ✅ Workspace version: 2.0.2
• ✅ kora-lib version: 2.0.2
• ✅ kora-cli version: 2.0.2
• ✅ kora-cli dependency on kora-lib: 2.0.2
• ✅ Cargo.lock updated correctly
• ✅ tests package inherits workspace version
• ⚠️ README.md still references v2.0.1 (see comment)

The hotfix addresses a critical issue where large v0 transactions using address lookup tables would fail with "transaction too big" errors when the system attempted to manually serialize them by converting to legacy format.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk - it's a straightforward version bump for a hotfix release
• This is a standard release PR with proper version synchronization across all workspace packages. The actual bug fix was already merged in PR hotfix: (PRO-639) Fix big transaction causing error when using v0 tra… #297, and this PR only updates version numbers and documentation. All version references are consistent (2.0.2 across workspace, kora-lib, kora-cli, and Cargo.lock). The CHANGELOG entry properly documents the hotfix. The only minor issue is that README.md references the old v2.0.1 release, but this doesn't affect the build or functionality.
• No files require special attention - all changes are straightforward version updates
