## Executive summary
Highlights from this release:
* major overhaul of admin interface,
* robust internal delete and flush notification,
* info-provider generates timestamps on published objects,
* pool migration module maintains last-access-time,
* pool implements strict LRU garbage collection,
* improved shutdown in space-manager,
* reserving space from a linkgroup may be authorised by GID,
* better scalability in FTP doors,
* new admin commands for nfs service,
* recording of FTS-specific information,
* xrootd doors support the protocol's asynchronous open.
* support for custom HTTP response headers
## Incompatibilities
* Java 8 is required for running dCache 2.13. Both the Oracle JDK and
OpenJDK are supported.
* The chimera schema is updated upon upgrade.
* The `admin` shell has been reimplemented and the user interface has changed.
* The `broadcast` service has been dropped and needs to be removed from the layout file.
* The `dir` service has been dropped and needs to be removed from the layout file.
* The `loginbroker` service has been dropped and needs to be removed
from the layout file.
* Support for JMS brokers (ActiveMQ and OpenMQ) has been removed.
* Support for Terracotta load balancing has been removed.
* The `httpd` service reads certificates from `/etc/grid-security` and no
longer uses Java Key Store files.
* The `dcache import` commands have been removed.
* `pnfsmanager` and `cleaner` services need to be configured according
to the presence of a `replica` or `spacemanager` service.
* dCache now defaults to expect a `spacemanager` service. If not present, several services
need to be configured not to expect a `spacemanager`.
* The default cell name of the `spacemanager` service was changed from
`SrmSpaceManager` to `SpaceManager`.
* The default database names and owners for all services have changed.
* The pool Berkeley DB meta data format has changed. No change is
required upon upgrading, but downgrading is not possible without
explicitly converting the format.
## Release 2.13.61
### admin
While `migration move` tasks on pools were working correctly, for `migration info` command an error occurred,
that the current user (root) wasn't allowed to execute anything (due to missing ACLs). This is now fixed.

## Release 2.13.60
### httpd
The "Disk Space Usage" webpage (`/usageInfo`) contains a table showing
information about each pool in the dCache cluster. The "Layout"
column showed the capacity usage graphically, with different colours
showing how much of that pool's capacity is being used for different
tasks. This release fixes the Layout heading to describe a previously
undocumented colour.

## Release 2.13.59
### webdav
A recent update, commit 5abc0e1c, improved the behaviour of the Milton WebDAV libraries if an IOException occurs
during an upload. That patch, unfortunately, did not address all issues, and when non-spec-conformant clients
are used against dCache, stacktraces can be triggered.
This patch corrects that behaviour. Also, in case of errors, the error code returned in case of any problems
was changed from 400 to 500, which should signal cliens that they are free to retry the transfer after a timeout.

## Release 2.13.58
### Changes affecting multiple services
The version of the PostgreSQL driver used by dCache internally was brought up to 9.4.1212. This fixes the issue described in [liquibase bug 2939](https://liquibase.jira.com/browse/CORE-2939).
### system-test
The system-test module, used for demonstration or testing purposes, comes with a built-in X.509 infrastructure. With this release, expired certificates are replaced by new ones.

## Release 2.13.56
### chimera
The current release fixed database query for storing multiple checksums for a file.
### ftp
The Socket `read` method may return zero to indicate that no bytes were
read. Although this is not an error, such occurances will result
in a transfer failing.
This is now fixed.

## Release 2.13.54
### ftp
The current release improves compatibility between dCache FTP client and Globus GridFTP server.
### srm
During an ATLAS stress-test of tape recalls, it was discovered that
various sites had relatively short request lifetimes. However, the SRM
spec provides the opportunity for the server to inform the client (FTS,
in this case) of what lifetime a request actually has.
The current release includes the requests remaining lifetime in the response from the server.
The current release improves the documentation to help Admins to have a better understanding how to configure dCache correctly.

## Release 2.13.53
### xrootd
In https://github.com/xrootd/xrootd/issues/459, it became apparent that dCache could improve xrdcp compatibility by sending
checksum information in lower case. This release contains this change, which should improve xrootd operations.

Users reported that they wanted to see space freed up by cleaner processes
to be reported as free as soon as possible. This patch sends notifications
about freed up space more often, resulting in quicker status updates.

## Release 2.13.49
### dcap
Connections of non-DCAP clients to a dCache no longer result in stack-traces in the logs.
### poolmanager
PoolManager was updated to properly handle the `dcache.authz.staging.pep` and `dcache.authz.staging` parameters. This allows to enable stage protection properly.

## Release 2.13.48
### Changes affecting multiple services
Internal notification processing between cleaners and Pin Manager, Replica Manager and Space Manager was improved and runs quicker now.
### billing
If a dCache instance was shut down while the billing service was in the middle of a refresh,
an exception was logged and shutdown was delayed. A change in exception handling fixes this rare
scenario, ensuring a quick shutdown and no unnecessary log entries.
### dcap
This release makes it possible for admins to ban outdated, problematic versions of dcap clients.
Some old client versions contain a bug that causes the
client to make unsatisfiable requests to a pool with no way for dCache
to reject the request: the client will simply retry.
The client version limits are exposed using the new configuration property `dcap.limits.client-version`.
The default is to allow all dcap client versions, unchanged from the previous behaviour.
This release fixes a regression through which Kerberos dcap would not work for host principals containing a '-' character. GSI dcap was not affected.
### doors
Fixed a bug in the lb set tags command in doors that prevented setting
an empty list of tags.
### pool
A bug that caused non-critical stack traces to be logged on the pool after
stage or deletion failure from nearline storage has been fixed.

## Release 2.13.46
### billing
Fixed a problem in the output of the `dcache billing` command using
JSON or YAML when the billing format includes a custom date format.
### dcap
Add support for the dcap client supplying additional version
information.
### gplazma
Fix `explain login` and `test login` commands so they are able to test
logging in with username and password.
Add examples to `explain login` command help. Our thanks to Onno
Zweers for this change.
### httpd
Fix regression in the `transfers.txt` output format.
Update the transfers.html page so it no longer includes `<unknown>`
for default/unknown protocols. With this version of dCache, these are
represented by a `?` character. The webadmin page is updated to give
consistent output.
### scripts
Fix the billing indexer to ignore the `format` string, if present.

### commons
If dCache's internal ShellApplication framework detects a critical behaviour
that might indicate a bug in the application, error messages now include
an explicit request to send a mail to the developers and more relevant
information for assessing and reproducing the situation.
### gplazma2
This release fixes a small bug in GPlazma which inappropriately
tried to handle non-DN subjects in x509 certificates.
These will usually fail in gPlazma anyway, but the reported error
was confusing.
### srm
Handling of DNS names without trailing dots in certificates has been made more robust and universal.

## Release 2.13.44
### cells
In rare cases, an interrupt needed to cleanly shut down the location manager connector would not arrive. This issue was corrected, ensuring more reliable behaviour on cell shutdown.
Fixed a problem in which threads could inappropriately be created as daemon threads,
causing problems in killing those threads when the cell shuts down.

## Release 2.13.43
### commons
The \s admin command uses the toString method to serialise the requested
so that the remote cell may correctly parse it. This did not always
work: '=' characters in arguments were escaped but not unescaped;
arguments that start with a '-' character were not escaped; empty words
were lost. In the current release this is fixed and \s command works as expected.
### dcache
The current release fixes a regression in which the exit code of check-config would
always be zero even when errors were detected.

## Release 2.13.42
### alarms
Alarm email notifications are now sent only on the first occurrence
of given alarm (i.e., for that alarm instance's unique ID).
If an alarm has been closed and not deleted,
but then occurs again, the counter for receiving that alarm
is now reset to 1, in order to treat this as a new (set of)
occurrences, and to guarantee a new notification will be sent.
### webadmin
Due to an implementation detail in a library used for the webadmin pages, filtering
tables was a bit unintuitive until now: A filter that was set in a certain table column would
reappear on tables in other browser windows if they had similar columns.
This behaviour was corrected, and tables on different pages exposed simultaneously in different
browser tabs are now filtered independently. However, the fix also has the side effect that
now with page reloads and form submissions the filters are cleared. Any commands, however, will
always be issued correctly.
Filtering rows in webadmin tables could occasionally lead to unintuitive behaviour with regard to selections:
Filtering a table and hiding rows may be included in a "select all" or "deselect all" operation.
This was fixed, and selection/Deselection of hidden rows is now prevented.
Issues with filter boxes disappearing or filters resetting have been solved by disabling
AJAX auto refresh for the affected pages.

## Release 2.13.41
### chimera
Chimera occasionally suffered from (operationally irrelevant) IllegalStateExceptions. Those are now avoided.
### doors
Doors could get stuck temporarily if a file was deleted during pool selection. This has been fixed, and in such cases, transfers are now aborted properly.

## Release 2.13.40
### billing
When using the `dcache billing` command with a non-default date format in the billing file, an unneccessary stack trace was printed. This has been corrected.
### srm
The SRM should periodically (by default every 10 minutes) delete obsolete historic data (older than 10 days by default) from the database. For cases where there are problems with that process, error logging and robustness against temporary database problems have been improved.

## Release 2.13.39
### ftp
The Apache Commons FtpClient can issue the LIST command with the
non-standard `-a` option. Which was causing dCache to switch
output format from the long (`ls -l`-like) to the short (`ls`-like)
response. This is fixed now and dCache is more compatible with Apache Commons FtpClient.

## Release 2.13.38
### cells
If the `create` command in CellShell fails because of unreadable setup files, it throws an IOException. This was incorrectly reported as a bug. Reporting has been corrected now.
In rare cases, active transfers would show up with an incorrect state in the active transfers page of the admin backend. This was fixed, so that ransfers which are staging from non-DCAP doors are correctly indicated (in yellow) on the active transfers page, instead of showing up as "No Mover found" (in red).
### common
If there is an IOException when trying to read a setup file, the corresponding file name is now listed in the error message.
### poolmanager
An issue with PoolManager prevented it from delivering correct cost estimates. This was fixed, resulting in improved estimations of pool load.

## Release 2.13.35
### alarms
A change to the alarms system improves handling of alarms with unset types.
### nfs
A race condition in the NFS door that could result in the creation of
multiple inconsistent copies of a file being uploaded has been fixed.
### pool
When a transfer's status is queried before the transfer is initiated,
which can occasionally happen for queued requests, Exceptions were logged.
This behaviour has now been corrected, providing more robust operation.
Several race conditions in the pool's migration module are fixed now.
A regression was fixed that caused pools to "leak" movers if those were cancelled
while still being queued.
### spacemanager
Fixes a compatibility problem with NFS in which space manager would fail with
a duplicate key error.
### srm
A hint to describe the necessity to include escaping has been added.
The current release fixes issues in which the use of SRM third party copy operations could cause
the SRM cell to become unresponsive, possibly even run out of memory.
