Upgrading and downgrading
==========================

How to Upgrade
--------------

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
bitcoind/bitcoin-qt (on Linux).

If you are upgrading from version 0.7.2 or earlier, the first time you run
0.9.3 your blockchain files will be re-indexed, which will take anywhere from
30 minutes to several hours, depending on the speed of your machine.

Downgrading warnings
--------------------

The 'chainstate' for this release is not always compatible with previous
releases, so if you run 0.9.x and then decide to switch back to a
0.8.x release you might get a blockchain validation error when starting the
old release (due to 'pruned outputs' being omitted from the index of
unspent transaction outputs).

Running the old release with the -reindex option will rebuild the chainstate
data structures and correct the problem.

Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan
the blockchain for missing spent coins, which will take a long time (tens
of minutes on a typical machine).

0.9.3 Release notes
=======================

RPC:
- Avoid a segfault on getblock if it can't read a block from disk
- Add paranoid return value checks in base58

Protocol and network code:
- Don't poll showmyip.com, it doesn't exist anymore
- Add a way to limit deserialized string lengths and use it
- Add a new checkpoint at block 295,000
- Increase IsStandard() scriptSig length
- Avoid querying DNS seeds, if we have open connections

Wallet:
- Check redeemScript size does not exceed 520 byte limit
- Ignore (and warn about) too-long redeemScripts while loading wallet

GUI:
- fix 'opens in testnet mode when presented with a BIP-72 link with no fallback'
- AvailableCoins: acquire cs_main mutex
- Fix unicode character display on MacOSX

Miscellaneous:
- key.cpp: fail with a friendlier message on missing ssl EC support
- Remove bignum dependency for scripts
- Upgrade OpenSSL to 1.0.1i (see https://www.openssl.org/news/secadv_20140806.txt - just to be sure, no critical issues for Bitcoin Core)
- Upgrade miniupnpc to 1.9.20140701
- Fix boost detection in build system on some platforms

that's a good news

[techman]

I just downloaded earlier version on my Mac 3 hours ago, Do I need re-download all of them and delete earlier version? :/

[CoinLearn]

I can see Gavin is not among the thanks list. Does not he contribute anymore ?

Not really. 0.9.2.1 is still the latest stable version. This is a release candidate, so is meant for testing.

I can see Gavin is not among the thanks list. Does not he contribute anymore ?

Not to this minor release, which has only a very small number of fixes. He did sign the DMG and MacOSX binaries. He certainly still contributes to the next major version (what is in git master).

Great! Is the increase in ScriptSig length to account for greater M and N values of M-of-N multisig transactions?

[jkrueger]

Great! Progress is a good thing

how to upgrade on ubuntu when stable version released? I could just do "apt-get upgrade bitcoin"?

Correct:

commit 84fe0ffd685627689bbbcd14cf419938f2a100b2
Author: Peter Todd <pete@petertodd.org>
Date:   Mon Mar 10 16:38:44 2014 -0400

    Increase IsStandard() scriptSig length
   
    Removes the limits on number of pubkeys for P2SH CHECKMULTISIG outputs.
    Previously with the 500 byte scriptSig limit there were odd restrictions
    where even a 1-of-12 P2SH could be spent in a standard transaction(1),
    yet multisig scriptPubKey's requiring more signatures quickly ran out of
    scriptSig space.
   
    From a "stuff-data-in-the-blockchain" point of view not much has changed
    as with the prior commit now only allowing the dummy value to be null
    the newly allowed scriptSig space can only be used for signatures. In
    any case, just using more outputs is trivial and doesn't cost much.

You will have to wait for the repo [1] to be updated. AFAIK the person looking after it does so pretty fast.

  On the run ... let's evaluate this if this build crash on WinXP like the 0.9.2.1  (please, no ! The 0.9.1 is rock stable, no crash at all)

[Meuh6879]

Sound good, no problem for now ... but it must pass the 48h of running time to rise in my mind. 

[Meuh6879]

  No ... after 19 hours of run ... it's crash without a debuglog entry (or error box displayed).
Like the 0.9.2 and 0.9.2.1

Thanks gotta download it rightway,I have to re-download the blockchain once again or it does merges with previous version i have installed

[shorena]

Did you have to quote the whole post for that single line?

Anyway, no you dont have to download the whole blockchain again, just close the existing installation and install the new one over it (e.g. in Win just run the setup w/o uninstalling)

[oceans]

This is great news any kind of progress whether it be for testing or not is always a good sign as it shows things are progressing in a way they should be and not keeping to a stand still.

[Lauda]

Excellent, fixes are good. I'm amazed by the number of opened issues though.
How far is some version with "new features"?
I'm going to upgrade today.

[wumpus]

No ... after 19 hours of run ... it's crash without a debuglog entry (or error box displayed).
Like the 0.9.2 and 0.9.2.1  

You don't get any kind of traceback or core dump from the OS either? We really need one to even start debugging this problem.
What is your usage scenario? Mining? A lot of RPC calls?
Does this happen in both bitcoin-qt and bitcoind?

[Meuh6879]

Since the 0.9.1 (rock stable), the new products of bitcoin-core crash without debuglog entry or error message (windows box).
I use BFGMiner to mining with 12GH/s USB miner.

First report of this crash is here : https://bitcointalk.org/index.php?topic=655359.msg7370223#msg7370223 (read the folowed message to retrace the bug).
