Top BDK 1.0 PRs and issues

alpha.3

Recently merged:

• build(esplora): Add async-https-rustls flag to esplora client bdk#1179
• ci: pin home dependency to 0.5.5 and check_clippy to rust stable version bdk#1247
• doc(bdk): Clarify the absolute_fee docs bdk#1158
• doc: Improve TxGraph & co docs bdk#1188
• Use a universal lookahead value for KeychainTxOutIndex and have a reasonable default bdk#1229
• Bump MSRV to 1.63.0 bdk#1183

Ready to be merged:

• ref(hwi): Move hwi out of bdk bdk#1161: needs to be rebased after CI fix, then it can be merged -> needs some more feedback by evan before merging

Need Review:

• Refactor/rename electrum_ext and esplora_ext to have sync and full_scan functions bdk#1235: review required -> needs some more review and then it's ready to be merged. Lower priority than 1203 and 1172

In Progress:

• Include the descriptor in keychain::Changeset bdk#1203: needs more discussion (?) and to be rebased, but being pretty important we can leave it to alpha.3 -> in progress but close to be committed. This will ideally be the next merge since it is the biggest one left for alpha.3
• Introduce block-by-block API to bdk::Wallet and add RPC wallet example bdk#1172: evan took it over. Needs review -> in progress. Close to be ready (probably tomorrow)

###Milestone TBD

• Introduce bdk::Wallet builder API bdk#1250: alpha.3 or alpha.4? -> alpha.4
• For wallet change sets persist and verify descriptor hashes bdk#1234: it is an alternative solution to Reintroduce descriptor data to bdk::Wallet persistence bdk#1101. The other solution proposed (#1203) is in alpha.3 -> needs another check to see if it can be closed or kept
• BIP 371 noncompliance: Taproot fields remain after adding PSBT_IN_FINAL_SCRIPTWITNESS in finalize_psbt bdk#1243: bug on taproot fields -> put in alpha.4 since it seems important
• The fact that the Wallet.transactions() API can return more than wallet-related txs is not explicit bdk#1239: discussion on what transactions the function Wallet.transactions() should return -> probably we need more documentation on that, put in alpha.4 in order to have it in sight
• Design block-by-block API bdk#1245: discussion on design of a block-by-block API -> will be closed when 1172 is merged

Other updates for future releases

• Liquid support bdk_wallet#118: on Liquid support. Seems very complicated, postponed -> we leave it open in case someone else wants to comment
• ci: add test with MSRV 1.63.0 rust-electrum-client#128 -> we are going to define an MSRV for the rust-electrum-client crate
