# Changelog
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## Unreleased
## 0.0.130
## 0.0.129
## 0.0.128
*NOTE: this release has not been published to crates.io*
- hdk: Adds external hash type for data that has a DHT location but does not exist on the DHT [\#1298](https://github.com/holochain/holochain/pull/1298)
- hdk: Adds compound hash type for linkable hashes [\#1308](https://github.com/holochain/holochain/pull/1308)
- hdk: Missing dependencies are fetched async for validation [\#1268](https://github.com/holochain/holochain/pull/1268)
## 0.0.127
## 0.0.126
- Docs: Explain how hashes in Holochain are composed and its components on the module page for `hdk::hash` [\#1299](https://github.com/holochain/holochain/pull/1299).
## 0.0.125
- hdk: link base and target are no longer required to exist on the current DHT and aren’t made available via. validation ops (use must\_get\_entry instead) [\#1266](https://github.com/holochain/holochain/pull/1266)
## 0.0.124
## 0.0.123
## 0.0.122
- hdk: `delete`, `delete_entry`, and `delete_cap_grant` can all now take a `DeleteInput` as an argument to be able specify `ChainTopOrdering`, congruent with `create` and `update`. This change is backward compatible: a plain `HeaderHash` can still be used as input to `delete`.
## 0.0.121
## 0.0.120
- docs: Add introduction to front-page and move example section up [1172](https://github.com/holochain/holochain/pull/1172)
## 0.0.119
- hdk: `encoding` from `holo_hash` re-exported as hdk feature [1177](https://github.com/holochain/holochain/pull/1177)
## 0.0.118
- hdk: `Path` now split into `Path` and `PathEntry` [1156](https://github.com/holochain/holochain/pull/1156)
- hdk: Minor changes and additions to `Path` methods [1156](https://github.com/holochain/holochain/pull/1156)
- hdk: `call` and `call_remote` are the same thing under the hood [1180](https://github.com/holochain/holochain/pull/1180)
## 0.0.117
## 0.0.116
## 0.0.115
## 0.0.114

## 0.0.112
## 0.0.111
## 0.0.110
## 0.0.109
## 0.0.108
## 0.0.107
### Changed
- hdk: `scheduled` fn signature updated to a string
### Added
- hdk: `map_extern_infallible` added to map infallible externs
- hdk: `schedule` function now takes a String giving a function name to schedule, rather than a Duration
## 0.0.106
## 0.0.105
## 0.0.104
## 0.0.103
### Changed
- hdk: `sys_time` returns `Timestamp` instead of `Duration`
### Added
- hdk: Added `accept_countersigning_preflight_request`
- hdk: Added `session_times_from_millis`
- hdk: Now supports creating and updating countersigned entries
- hdk: Now supports deserializing countersigned entries in app entry `try_from`
- hdk: implements multi-call for:
- `remote_call`
- `call`
- `get`
- `get_details`
- `get_links`
- `get_link_details`
We strictly only needed `remote_call` for countersigning, but feedback from the community was that having to sequentially loop over these common HDK functions is a pain point, so we enabled all of them to be async over a vector of inputs.
## 0.0.102
### Changed
- hdk: fixed wrong order of recipient and sender in `x_25519_x_salsa20_poly1305_decrypt`
## 0.0.101
### Changed
- Added `HdkT` trait to support mocking the host and native rust unit tests
### Added
- Added `sign_ephemeral` and `sign_ephemeral_raw`
## [0.0.100](https://github.com/holochain/holochain/compare/hdk-v0.0.100-alpha1..hdk-v0.0.100)
### Changed
- hdk: fixup the autogenerated hdk documentation.
## 0.0.100-alpha.1
### Added
- holochain 0.0.100 (RSM) compatibility
- Extensive doc comments
