 # Changelog
 
+## [2.0.0] - 2026-08-26
+
+### Breaking Changes
+
+- Removed `multisig-permissions`, `trc20-toolkit-skill`, `trx-staking-skill`, `twitter-digest`, and
+  `twitter-mcp`. Generic TRON workflows are now handled by `wallet-cli`; X/Twitter workflows no
+  longer belong to this DeFi-focused Skills collection.
+- Unified every retained Skill version with the repository release version.
+
+### Features
+
+- Added the `wallet-cli` skill for machine-readable TRON wallet, transfer, staking, governance,
+  contract, signing, permission, and chain-query operations.
+- Added a root version source, repository versioning policy, and CI consistency check.
+
+### Security
+
+- Preserved exact-token-approval, staking/unfreezing, voting, and permission-lockout guidance in
+  the consolidated `wallet-cli` safety reference.

+# Versioning
+
+This repository uses one release version for the complete Skills collection.
+
+## Source of truth
+
+The root [`VERSION`](./VERSION) file is the source of truth. Its value uses Semantic Versioning
+without a leading `v`.
+
+The same version must appear in:
+
+- every top-level `*/SKILL.md` frontmatter `version` field;
+- every top-level skill `package.json` that declares a version;
+- the newest entry in `CHANGELOG.md`.
+
+Release tags add the conventional prefix: version `2.0.0` is tagged `v2.0.0`. Do not create
+independent per-skill release tags. A change to any skill is released as a new repository version,
+and all skill frontmatter versions advance together even when a particular skill did not change.
+
+## Dependency versions
+
+External CLI, SDK, runtime, and service versions are independent of the repository release. Keep
+them in each skill's `dependencies`, prerequisites, and installer. Financial execution CLIs should
+normally use an exact tested version; use a range only when the skill intentionally supports and
+tests that complete range.
+
+For example:
+
+```yaml
+version: 2.0.0
+dependencies:
+  - "@tron-walletcli/wallet-cli@4.12.0"
+```
+
+Here `2.0.0` is the BofAI Skills release and `4.12.0` is the independently maintained CLI version.
+
+## Release rules
+
+- Patch: documentation corrections and backward-compatible fixes.
+- Minor: backward-compatible skill additions or workflow improvements.
+- Major: removed skills, renamed skills, incompatible trigger or workflow changes, or changed
+  authorization/security contracts.
+
+Before opening a release, update `VERSION`, all skill and package mirrors, and `CHANGELOG.md`, then
+run:
+
+```bash
+sh scripts/check_versions.sh
+```
