# Change Log

All notable changes to the CAPS client library will be documented in this file.

## 2021-04-21 1.0.0
### Changed
- Set library version to 1.0.0

## 2021-02-16
### Added
- Allow to set maximum allowed future end time via plugin API. In additon
  add commandline and config support to the plugin application class e.g.
  ```
  output.maxFutureEndTime = 120
  ```
  By default the option is set to 120 seconds.

## 2020-12-14
### Added
- Support to set miniSEED record length via API

## 2020-09-22
### Changed
- Use last sample time as reference time for maximum future time check. Before
  we used the packet end time as reference time but this makes no sense in case
  of low sampled data.
- So far we used the current time as start time if journal entries exceeded the
  maximum allowed future time. With this release we use the journal time no
  matter what its value but display a warning when the journal time is more than
  one day in the future.

## 2020-06-22
### Added
- Python3 byte array support to any record push

## 2020-02-21
### Changed
- Increase default timeout for acknowledgement messages from 5s to 60s

## 2019-09-24
### Fixed
- Fix high load if packets could not be sent to CAPS. In that case the plugin
  automatically reconnects after some amount of time. If triggered under certain
  circumstances this delay was not in effect and caused unnecessarily high
  amount of connection attempts. Under some circumstances the plugin could have
  crashed due to a stack overflow.
- The quit method has now the semantics to continue pushing packets as long
  as the connection is established and only abort in case of an error without
  attempting a reconnect.

## 2019-09-20
### Fixed
- Fix error string if not all data could be sent to the server

## 2019-08-19
### Changed
- Discard packets whose end time is more than 120 seconds before the system time.

## 2019-08-06
### Added
- new config option ``output.addr``

### Fixed
- ambiguous command line option ``-h``. With this version of the library the
host and port can be set via the command line option ``--addr``.
- wrong config option parsing

## 2019-08-05
### Fixed
- seg fault in date time parser

## 2019-08-02
### Fixed
- Hanging TCP connections. In case of the remote side does not shutdown cleanly
the plugin did not notice that the connection is no longer available. With this
version the plugin reconnects to the server when the TCP send buffer is full and
tries to send all not acknowledged packets again.
- Do not discard packets if the packet buffer is full. Instead we block until
the server acknowledges some packets.

### Changed
- The plugin application class checks whether the configured buffer size is
below the minimum.

## 2019-07-05
### Changed
- Ignore journal entries where the timestamp is more than 10 seconds
  before the system time.

## 2018-12-19
### Fixed
- Read journal from file in plugin application.

## 2018-12-18
### Fixed
- Do not reconnect if the plugin buffer is full. Instead of we try to read
acknowledgements from the CAPS server until the plugin buffer is below the
threshold.

## 2018-12-17
### Added
- Support to retrieve status information e.g. the number of buffered bytes from
  plugin.

## 2018-09-06
### Changed
- Enable more verbose logging for MSEED packets

## 2018-07-25
### Fixed
- unset variable of the raw data record
- trim function will return false in case of an unknown datatype

## 2018-05-30
### Fixed
- Fixed unexpected closed SSL connections

## 2018-06-05
### Fixed
- Fix RawDataRecord::setHeader

## 2018-05-16
### Fixed
- RAW data end time calculation

## 2018-03-19
### Added
- SSL support

## 2017-11-20
### Added
- float and double support for Steim encoders. All values will be converted implicitly
to int 32 values

## 2017-11-08
### Added
- timing quality parameter to push call. By default the timing quality is set to -1.

## 2017-11-07
### Fixed
- do not flush encoders after reconnect

## 2017-10-26
### Added
- SSL support


## 2017-10-24
### Fixed
- packet synchronization error after reconnect
