-# Releasing Roles Binaries and Publishing
+# Versioning
 
-The github binary releases of the roles and the publishing of the SRI crates are both handled in the `release.yaml` workflow. This workflow must be manually
-started by navigating to the "Actions" tab in the SRI repo, then navigating to the Release workflow section, and clicking "Run Workflow".
+SRI releases follow [SemVer 2.0.0](https://semver.org/).
 
-## Crates Publishing
+Given a version number `MAJOR.MINOR.PATCH`, we increment the:
+- `MAJOR` version when incompatible API changes are introduced
+- `MINOR` version when functionality is added in a backward compatible manner
+- `PATCH` version when backward compatible bug fixes are introduced
 
-For publishing crates we use the `cargo-release` tools because it easily handles the order in which crates can be published. Crates are published 
-in the `crates_publish` job. Currently, crates.io rate limits the publishing of more than 5 NEW crates. This means that if we have more than 5 crates
-to publish, that are not currently published to crates.io, this workflow will not publish anything. To bypass this we will need to add the `--exclude [crate_name]`
-flag for as many crates as needed to the `cargo-release` command in the "Publish" step. For example, if there are 7 new crates to publish, we will need to add 
-`--exclude [crate_1] --exclude [crate_2]` to the command. This is not an issue for publishing version updates since the crates are not NEW publishes.
+SRI has a global version, which uses git tags and keeps track of how the codebase evolves across time as a whole.
 
-### Current Successful Publishes
+Every internal SRI crate also follows SemVer 2.0.0, but each crate version is only set on the respective `Cargo.toml`,
+(no git tags), and it evolves independently of the global release version.
 
-Due to either github dependencies or a crate failing the build stage during publish not all crates are being published.
+Whenever a `PATCH` is introduced, it is applied to all the latest `MAJOR` releases.
+For example: imagine there's releases `v1.0.0`, `v1.1.0`, and `v2.0.0`. A bug is found, dating back all the way to `v1.0.0`.
+A patch is applied such that the following new tags are introduced: `v1.1.1` and `v2.0.1`.
 
-- [x] buffer_sv2
-- [x] binary_codec_sv2
-- [x] binary_sv2
-- [x] common_messages_sv2
-- [x] const_sv2
-- [x] derive_codec_sv2
-- [x] framing_sv2
-- [x] serde_sv2
-- [x] sv1_api
-- [] noise_sv2 - github depependency (ed25519-dalek)
-- [] codec_sv2 - noise dependency
-- [] template_distribution_sv2 - build failure
-- [] mining_sv2 - publishes after template_distribution_sv2
-- [] job-declaration_sv2 - publishes after template_distribution_sv2
-- [] roles_logic_sv2 - publishes after template_distribution_sv2
-- [] network_helpers - publishes after template_distribution_sv2
-- [] error_handling - had to exclude to bypass rate limit but will probably publish now
-- [] sv2_ffi - had to exclude to bypass rate limit but will probably publish now
-- [] all roles - noise dependency
+# Git Branching Strategy
 
-## Github Roles Releases
+We follow a simplified [gitflow](https://nvie.com/posts/a-successful-git-branching-model/) branching strategy.
 
-The roles binaries are released in github in all jobs other than the `crates_publish` job. To be able to publish,
-the job must be able to find a new tag (one that hasnt already been released), matching the crate name of the role to be
-released. For example, imagine there is currently a release for pool_sv2-v1.0.0. For the jobs releasing a new pool version to succeed,
-it must be able to find a tag containing the string "pool_sv2" with a version greater than 1.0.0. This should not be an issue since the tags
-are automatically created by the `autoversion.yaml` workflow, and moved into main when the generated PR is merged.
+Although our strategy is very similar to the classic gitflow model, we do not keep release branches.
 
-### Github Release Issue
+![](git-branching.png)
 
-Currently we do not support windows releases because we are unable to run the step to return the last tag for a given crate name. See the section above
-for an explaination of the process.
+## Principal Branches
 
+The SRI repo holds two principal branches with an infinite lifetime:
+- `main`
+- `dev`
 
+We consider `main` to be the branch where the source code of `HEAD` always reflects a production-ready state.
 
-## Github Binary Releases
+We consider `dev` to be the branch where the source code of `HEAD` always reflects a state with the latest delivered development changes for the next release.
 
-# Versioning
+The SRI team will decide the appropriate time when the changes to `dev` are merged back into `main` and then tagged with a release number while bumping `MAJOR` and/or `MINOR`.
+
+## Feature Branches
+
+New features are developed into separate branches that only live in the contributor's forks.
+
+- branch off from: `dev`
+- merge back into: `dev`
+- naming convention: `feat-x`, where `x` describes the feature
+
+## Patch Branches
+
+Bugs are patched into separate branches that only live in the contributor's forks.
+
+- branch off from: `main`
+- merge back into: `main` + `dev`
+- naming convention: `patch-x`, where `x` describes the bug/patch
+
+# Releasing Roles Binaries
+
+The [release page of SRI repo](https://github.com/stratum-mining/stratum/releases) provides executable binaries for all SRI roles, targeting popular hardware architectures.
+
+The GitHub binary releases of the roles are handled in the `release-bin.yaml` workflow.
+
+This workflow is manually started by navigating to the "Actions" tab in the SRI repo, then navigating to the Release workflow section, and clicking "Run Workflow".
+
+Note: in order to be able to manually trigger the "Run Workflow" button, the user needs to have "Write" permissions on the repository, otherwise the button will not show up on the UI.
+
+# Publishing Library Crates
+
+Although SRI has a global release cycle, which is attached to the binaries, each internal crate also has its own versioning history.
+
+Lib crates are published to crates.io in the `release-lib.yaml` workflow. The workflow tries to update all the library crates. 
+
+If a crate is not updated successfully, the step will fail, but since all steps have `continue-on-error` set to true, the workflow will continue.
+
+Since steps can fail, the output of the action must be manually checked.
 
-Versioning is handled by the `autorelease.yaml` workflow. The workflow will  will auto detect changes in crates and auto bump the patch versions 
-in the target crate, as well as any crate that uses the target crate as a dependency, if changes are detected. It will then push a new commit with the 
-versioning changes to the `bot/versioning` branch, and Lastly, it will auto create a PR (bot/versioning -> main). Since cargo-smart-release does not yet 
-support autodetection of MAJOR and MINOR changes with regards to Semver, any MAJOR/MINOR versioning will need to be manually changed in the package Cargo.toml.
+Every PR to `main` (either coming from `dev`, or a patch) needs to increase the version of whatever crate it is touching. Otherwise, we will mess up the dependency chain of whoever is fetching from crates.io
 
-## Versioning Notes
+Manually running `cargo release` in the various workspaces helps to prepare the version number before the releases are published.
 
-This workflow should not run if the push is resulting from this workflow, but this not necessarily guaranteed since the 
-a developer could make a minor change to the bot/versioning PR, and the latest author would no longer be "Github Actions Bot".
-If the workflow does run again, there will just be no changes, and the PR can be closed.
+Every time we bump some crate's version, `release-libs.yaml` needs to be manually triggered in order to update crates.io.
