Updates hardhat from 2.8.4 to 2.12.5

Release notes

Sourced from hardhat's releases.

Hardhat v2.12.5

• The full return data of unrecognized custom errors is now shown in error messages
• Fixed a bug that was causing the flatten task to produce non-deterministic results
• Fixed a bug when gasPrice was set to "auto", which is the default configuration when connecting to a JSON-RPC network. This bug was preventing the results from eth_feeHistory from being used when they should.
• Added an experimental environment variable flag to disable the local installation check (thanks @​arijoon!)

Hardhat v2.12.4

This release fixes a small issue that was affecting our VSCode extension in some edge cases.

It also includes a non-intrusive message promoting this year's Solidity Developer Survey.

Hardhat v2.12.3

• Added a new hardhat_metadata RPC method
• Trim leading and trailing spaces in mnemonics (thanks @​winor30!)
• Pending blocks now include the bloom field (thanks @​InoMurko!)
• A better error is shown if a Solidity file makes an import through its own package name (thanks @​KaanKC!)
• Added a getBuildInfoSync function to the hre.artifacts object (thanks @​emretepedev!)
• Fixed an edge case where Hardhat would hang if debug_traceTransaction was used with an OOG transaction sent to a precompile

Hardhat v2.12.2

• Fixed an issue when forking networks like Arbitrum Nitro that use non-standard transaction types (#2995, #3194).
• Fixed an issue that was causing build-info file names to not be deterministic.

Hardhat v2.12.1

Fixed a problem that was preventing Hardhat from being used in Alpine Linux.

Hardhat v2.12.0

This new minor version sets the merge hardfork as the default hardfork used by the Hardhat Network. Most users shouldn't be affected by this change.

Besides that, this version fixes a couple of issues related to our compilation pipeline.

Hardhat v2.11.2

This new version of Hardhat brings several fixes and improvements:

• Solidity 0.8.17 is now supported and used by default in the sample projects.
• When forking a network, the disk cache is always used (thanks @​bernard-wagner!)
• Stack traces are shown by default in CI servers
• We fixed a problem related to the validation of the eth_getStorageAt being too restrictive (thanks @​aathan!)
• Reverted an unintentional breaking change in the type of the resolved config
• Improved the heuristic for detecting that a contract deployment failed because the code size was too large

Hardhat v2.11.1

This release fixes a couple of bugs in v2.11.0:

• Some chains, like Polygon, were causing issues when they were forked
• The WASM version of the solidity compiler, which is used in some machines, was not being correctly downloaded.

Hardhat v2.11.0 — The Merge support and fast compilation

We are excited to release this new version of Hardhat, as it makes Hardhat Network compatible with The Merge and makes our compilation much faster. Read on to learn more about these and other improvements.
