The format is based on Keep a Changelog. This project adheres to Semantic Versioning.
- Bump
holochain_wasmer_*crates to v0.0.77 which relaxes the version requirements onserde. #1204
- Fixes D-01415 holochain panic on startup #1206
- hdk:
delete,delete_entry, anddelete_cap_grantcan all now take aDeleteInputas an argument to be able specifyChainTopOrdering, congruent withcreateandupdate. This change is backward compatible: a plainHeaderHashcan still be used as input todelete.
- New arc resizing algorithm based on
PeerViewBeta - In both arc resizing algorithms, instead of aiming for the ideal target arc size, aim for an ideal range. This slack in the system allows all agents to converge on their target more stably, with less oscillation.
- Bump holochain-wasmer to fix a compilation issue. #1194
- docs: Add introduction to front-page and move example section up 1172
- Fixes issue where holochain could get stuck in infinite loop when trying to send validation receipts. #1181.
- Additional networking metric collection and associated admin api
DumpNetworkMetrics { dna_hash: Option<DnaHash> }for inspection of metrics #1160 - BREAKING CHANGE - Schema change for metrics database. Holochain will persist historical metrics once per hour, if you do not clear the metrics database it will crash at that point. #1183
- Adds better batching to validation workflows for much faster validation. #1167.
- Adds the ability to manually insert elements into a source chain using the
AdminRequest::AddElementscommand. Please check the docs and PR for more details / warnings on proper usage. #1166
- hdk:
Pathnow split intoPathandPathEntry1156 - hdk: Minor changes and additions to
Pathmethods 1156
- BREAKING CHANGE: Range filters on chain queries are now INCLUSIVE and support hash bounds #1142
- BREAKING CHANGE: Chain queries now support restricting results to a list of entry hashes #1142
- BREAKING CHANGE Removed
app_infofrom HDK 1108 - Permissions on host functions now return an error instead of panicking 1141
- Add
--build-infoCLI flag for displaying various information in JSON format. #1163
- Gets won’t return private entries unless you are have committed a header for that entry. #1157
- Fixes database queries that were running on the runtime thread instead of the background thread. Makes the connections wait for a permit before taking a database connection from the pool. #1145
- Adds
basis_hashindex toDhtOptable. This makes get queries faster. #1143
- Agent info is now published as well as gossiped. #1115
- BREAKING: Network wire message has changed format so will not be compatible with older versions. 1143.
- Fixes to gossip that allows batching of large amounts of data. 1143.
- BREAKING CHANGE - Gossip now exchanges local peer info with
initiateandacceptrequest types. #1114.
- BREAKING CHANGES: db_sync_level changes to db_sync_strategy. Options are now
FastandResilient. Default isFastand should be the standard choice for most use cases. #1130
- Some databases can handle corruption by wiping the db file and starting again. #1039.
- BREAKING: Wire message
CallRemoteTakesfrom_agent. #1091
- BREAKING CHANGES: All DHT data for the same DNA space is now shared in the same database. All authored data for the same DNA space is also now shared in another database. This requires no changes however data must be manually migrated from the old databases to the new databases. #1130
- BREAKING: Wire message
Callno longer takesfrom_agent. #1091
- Fix issue where private dht ops were being leaked through the incoming ops sender. 1104.
- Kitsune now attempts to rebind the network interface in the event of endpoint shutdown. Note, it’s still recommended to bind to
0.0.0.0as the OS provides additional resiliency for interfaces coming and going. #1083 - BREAKING CHANGE current chain head including recent writes available in agent info #1079
- BREAKING (If using new lair) If you are using the new (non-legacy)
lair_serverkeystore, you will need to rebuild your keystore, we now pre-hash the passphrase used to access it to mitigate some information leakage. #1094 - Better lair signature fallback child process management. The child process will now be properly restarted if it exits. (Note this can take a few millis on Windows, and may result in some signature errors.) #1094
- Fixes: Bug where database connections would timeout and return
DatabaseError(DbConnectionPoolError(Error(None))). #1097.
- BREAKING CHANGE: Add all function names in a wasm to the zome info #1081
- BREAKING CHANGE: Added a placeholder for zome properties on zome info #1080
-
remote_signalhas always been a fire-and-forget operation. Now it also uses the more efficient fire-and-forget “notify” low-level networking plumbing. #1075 -
BREAKING CHANGE
entry_defsadded tozome_infoand referenced by macros PR1055 -
BREAKING CHANGE: The notion of “cell nicknames” (“nicks”) and “app slots” has been unified into the notion of “app roles”. This introduces several breaking changes. In general, you will need to rebuild any app bundles you are using, and potentially update some usages of the admin interface. In particular:
- The
slotsfield in App manifests is now calledroles - The
InstallAppadmin method now takes arole_idfield instead of anickfield - In the return value for any admin method which lists installed apps, e.g.
ListEnabledApps, any reference to"slots"is now named"roles" - See #1045
- The

Adds test utils for creating simulated networks. #1037.
-
Conductor can take a mocked network for testing simulated networks. #1036
-
Added
DumpFullStateto the admin interface, as a more complete form ofDumpStatewhich returns fullVec<DhtOp>instead of just their count, enabling more introspection of the state of the cell #1065. -
BREAKING CHANGE Added function name to call info in HDK. #1078.
- BREAKING CHANGE. Source chain
querywill now return results in header sequence order ascending.
- BREAKING: Return
ShardedGossipWire::Busyif we are overloaded with incoming gossip. #1076- This breaks the current network protocol and will not be compatible with other older versions of holochain (no manual action required).

danger_passphrase_insecure_from_config: "test-passphrase"or:
keystore:
type: danger_test_keystore_legacy_deprecated- Fix authority side get_links query #1027.
- Check local agents for basis when doing a RPCMulti call. #1009.
- Make validation run concurrently up to 50 DhtOps. This allows us to make progress on other ops when waiting for the network. #1005
- FIX: Prevent the conductor from trying to join cells to the network that are already in the process of joining. #1006
- Fixed a bug when creating an entry with
ChainTopOrdering::Relaxed, in which the header was created and stored in the Source Chain, but the actual entry was not. - Geneis ops will no longer run validation for the authored node and only genesis self check will run. #995
- Update to lair 0.0.7 which updates to rusqlite 0.26.0 #1023

- Fix to gossip’s round initiate. We were not timing out a round if there was no response to an initiate message. #1014.
- Make gossip only initiate with agents that have info that is not expired. #1014.
- Refactor conductor to use parking lot rw lock instead of tokio rw lock. (Faster and prevents deadlocks.). #979.
- The scheduler should work now
query_gossip_agents,query_agent_info_signed, andquery_agent_info_signed_near_basisare now unified into a singlequery_agentscall inKitsuneP2pEvent
- Adds a prototype protocol for checking consistency in a sharded network.
- Added support for
#[hdk_extern(infallible)]
- Adds experimental feature for one storage agent per space to kitsune tuning params.
gossip_single_storage_arc_per_space. - Adds the ability to lower the synchronous level for the sqlite backend to the conductor config.
db_sync_level. See sqlite documentation. This allows running on slower HDD but can result in corrupted databases and is not recommended for production or SSDs. - Fixes bug where WAL mode was set on every opening connection.
- Added helper functions to
WebAppBundleandAppManifestto be able to handle these types better in consuming applications.
- hdk:
schedulefunction now takes a String giving a function name to schedule, rather than a Duration
- Added
Scheduleenum to define schedules
- HDK
sys_timenow returns aholochain_zome_types::Timestampinstead of acore::time::Duration. - Exposes
UninstallAppin the conductor admin API.
- Added the
hc web-appsub-command for bundling up a UI with a previously created hApp bundle. It uses the same same behavior ashc dnaandhc appto specify the .yaml manifest file.
- Added
UninstallAppcommand.
- Added the
hc web-appsubcommand, with the exact same behaviour and functionality ashc dnaandhc app.
- Added
WebAppManifestto support.webhappbundles. This is necessary to package hApps together with web UIs, to export to the Launcher and Holo.
- Crate now builds with
--no-default-features

passphrase: "foobar"- Updated to lair 0.0.3
- switch to sqlite/sqlcipher for keystore backing database
- enable encryption via passphrase (not on windows)
- hdk:
sys_timereturnsTimestampinstead ofDuration
-
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_callcallgetget_detailsget_linksget_link_details
We strictly only needed
remote_callfor 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.
- Countersigning related functions and structs
- We’ve become aware of a bug that locks up the conductor when installing happ bundles or registering DNA via the admin API concurrently. Please perform these actions sequentially until we’ve resolved the bug.
- Concurrent zome calls could cause the
init()zome callback to run multiple times concurrently, causingHeadMovederrors. This is fixed, so thatinit()can only ever run once.- If a zome call has been waiting for another zome call to finish running
init()for longer than 30 seconds, it will timeout.
- If a zome call has been waiting for another zome call to finish running
- Apps now have a more complex status. Apps now can be either enabled/disabled as well as running/stopped, the combination of which is captured by three distinctly named states:
- “Running” (enabled + running) -> The app is running normally
- “Paused” (enabled + stopped) -> The app is currently stopped due to some minor problem in one of its cells such as failed network access, but will start running again as soon as it’s able. Some Cells may still be running normally.
- “Disabled” (disabled + stopped) -> The app is stopped and will remain so until explicitly enabled via
EnableAppadmin method. Apps can be disabled manually viaDisableApp, or automatically due to an unrecoverable error in a Cell.
- Some admin methods are deprecated due to the app status changes:
ActivateAppis deprecated in favor ofEnableAppDeactivateAppis deprecated in favor ofDisableApp
- Apps will be automatically Paused if not all of their cells are able to join the network during startup
InstallAppBundlecommand added to admin conductor API. #665DnaSourcein conductor_apiRegisterDnacall now can take aDnaBundle#665- New admin interface methods:
EnableApp(replacesActivateApp)DisableApp(replacesDeactivateApp)StartApp(used to attempt to manually restart a Paused app)
- Using the 3 level PLRU instance cache from latest holochain wasmer
v0.0.72
- hdk: fixed wrong order of recipient and sender in
x_25519_x_salsa20_poly1305_decrypt
❗ Performance impact
Please navigate to the holochain crate release notes further down for details on the performance impact in this release.
This version contains breaking changes to the conductor API as well as a major upgrade to the underlying Wasm runtime.
❗ Performance impact
The version of wasmer that is used in this holochain release contains bugs in the scoping of wasmer modules vs. instances, such that it blocks the proper release of memory and slows down execution of concurrent Wasm instances. While we were able to at least mitigate these effects and are coordinating with wasmer to find a proper solution as soon as possible.
The severity of these issues increases with cell concurrency, i.e. using multiple cells with the same DNA. Application development with a single conductor and a few cells are expected to work well unless your machine has serious resource restrictions.
InstallAppBundlecommand added to admin conductor API. #665DnaSourcein conductor_apiRegisterDnacall now can take aDnaBundle#665
- BREAKING:
InstallAppDnaPayloadin admin conductor APIInstallAppcommand now only accepts a hash. Both properties and path have been removed as per deprecation warning. Use eitherRegisterDnaorInstallAppBundleinstead. #665 - BREAKING:
DnaSource(Path)in conductor_apiRegisterDnacall now must point toDnaBundleas created byhc dna packnot aDnaFilecreated bydna_util#665
- Updated to a version of
holochain_wasmerthat includes a migration to wasmer v2+. #773, #801, #836 - Introduced a simple instance cache to mitigate and potentially outweigh the effects of the aforementioned wasmer conditions #848
- temporarily removed
install_appfromhc: its not clear if we should restore yet as mostly should be usinginstall_app_bundle#665
- BREAKING: All references to
"uuid"in the context of DNA has been renamed to"uid"to reflect that these IDs are not universally unique, but merely unique with regards to the zome code (the genotype) #727
- Added
HdkTtrait to support mocking the host and native rust unit tests
- Added
sign_ephemeralandsign_ephemeral_raw
Signatureis a 64 byte ‘secure primitive’
- Named bytes fixturators like
SixtyFourBytesare now fixed length arrays
- Added
SixtyFourBytesVecto work like the oldVec<u8>implementation
This will include the hdk-0.0.100 release.
- hdk: fixup the autogenerated hdk documentation.
This release was initiated for publishing the HDK at version 0.0.100-alpha.1. We are in the process of redefining the release process around this repository so rough edges are still expected at this point.
- Added App Validation workflow that runs app validation as authority #330
- Added validation package to entry defs see for usage #344
- Implemented the
emit_signalshost function #371, which broadcasts a signal across all app interfaces (fine-grained pub/sub to be done in future work) - get_details on a HeaderHash now returns the updates if it’s an entry header
- call host fn (This is an actual function not a macro). Allows you to call a zome that is installed on the same conductor. #453
- Added create link HeaderHash to the Link type
remote_signalhost function to send a signal to a list of agents without blocking on the responses. See #546 or the docs for the hdk.hcutility. Work with DNA and hApp bundle files, set up sandbox environments for testing and development purposes, make direct admin calls to running conductors, and more.
- BREAKING: get_details and get_links_details return SignedHeaderHashed instead of the header types #390
- BREAKING: ZomeInfo now returns the ZomeId #390
- BREAKING: HoloHash now serializes as a plain 39-byte sequence, instead of a
{hash, hash_type}structure #459 - BREAKING: (Almost) all HDK functions have been converted from macros to functions #478
- Admin interface method
install_apphas itsapp_idfield renamed toinstalled_app_idso as not to conflict with the future concept of an “app id” - Admin interface method
list_active_app_idsrenamed tolist_active_apps - BREAKING: JSON replaced with YAML for DNA Properties as well as the DNA manifest (dna.yaml instead of dna.json) #592
- BREAKING: format of AppInfo changed
- The
dna_utilhas absorbed by the newhcutility.
- If installing the same app_id twice, previously the second installation would overwrite the first. Now it is an error to do so.
